418:
New species and records of Lathrobium from the Palaearctic region, primarily from Nepal (Coleoptera: Staphylinidae: Paederinae). – Eighteen species of Lathrobium Gravenhorst, 1802 from Nepal (16 species) and China (2 species) are described and illustrated: L. semicirculatum sp. n. (E-Nepal; L. nepalense group); L. constrictum sp. n. (E-Nepal; L. discissum group); L. descendens sp. n. (W-Nepal; L. deuvei group); L. ascendens sp. n. (W-Nepal; L. deuvei group); L. rude sp. n. (C-Nepal: Dhaulagiri; L. emodense group); L. latibasale sp. n. (W-Nepal; L. pectinatum group); L. eques sp. n. (W-Nepal; L. pectinatum group); L. equitans sp. n. (C-Nepal: Dhaulagiri; L. pectinatum group); L. abruptum sp. n. (W-Nepal; L. pectinatum group); L. kemum sp. n. (C-Nepal: Dhaulagiri; L. pectinatum group); L. flexaculeatum sp. n. (C-Nepal: Dhaulagiri; L. pectinatum group); L. rectaculeatum sp. n. (C-Nepal: Dhaulagiri; L. pectinatum group); L. curvaculeatum sp. n. (C-Nepal: Dhaulagiri; L. pectinatum group); L. hebes sp. n. (C-Nepal: Dhaulagiri; L. pectinatum group); L. imberbe sp. n. (W-Nepal; L. pectinatum group); L. plicatum sp. n. (C-Nepal: Dhaulagiri; L. pectinatum group); L. glabrimpressum sp. n. (China: Yunnan: Gaoligong Shan; group assignment uncertain); L. smetanai sp. n. (China: Gansu: Dalija Shan; L. lentum group). Based on new material, a redescription and new illustrations of L. aculeatum Coiffait, 1982 are provided. Recently collected material of L. calcaratum Assing, 2012 suggests that the holotype of this species may have been mislabelled and that, consequently, the type locality is erroneous. The species previously assigned to the L. aculeatum group are moved to the L. pectinatum group, and the L. aculeatum group is discarded. Several species of the L. pectinatum group were found to be subject to a sexual dimorphism of body size. Additional records of six named species are reported from the West Caucasus (2 species) and from Nepal (4 species). Including the newly described species, the genus is currently represented in the Himalaya by 68 species in ten species groups, in China by 189 species, and in the Palaearctic region by 536 named species and ten subspecies.

A revision of the species  of Pinobius MacLeay, 1871 of the Oriental, Palaearctic, and Australian Regions (Coleoptera: Staphylinidae: Paederinae). – The species of the dolicaonine genus Pinobius MacLeay, 1871 (Coleoptera: Staphylinidae: Paederinae: Dolicaonina) of the Oriental, Palaearctic, and Australian Regions are revised. In all, 28 species are recognized, among them 14 species new to science: P. baculatus sp.n. (Indonesia: Java, Sumba), P. bifidus sp.n. (North India), P. bihamatus sp.n. (Myanmar), P. brevincisus sp.n. (South Vietnam), P. carinatus sp.n. (India: Maharashtra), P. discrepans sp.n. (Australia), P. extensus sp.n. (Papua New Guinea), P. firmilobatus sp.n. (Thailand, Singapore, Peninsular Malaysia, Sabah), P. formidabilis sp.n. (Malaysia), P. imberbis sp.n. (India: Assam), P. inaequalis sp.n. (Indonesia: Sulawesi), P. linguatus sp.n. (Bangladesh), P. rotundatus sp.n. (India: Assam), P. subaequalis sp.n. (Indonesia: Sulawesi). All the species are (re-)described and illustrated. Pinobius vicinus (Kraatz, 1859), previously a synonym of P. indicus (Kraatz, 1859), is revalidated. The following synonymies are proposed: P. indicus (Kraatz, 1859) = longipennis (Cameron, 1931), syn.n.; P. paricolor (Fauvel, 1878) = similis Last, 1984, syn.n.; P. sparsiventris (Fauvel, 1886) = javanus (Cameron, 1936), syn.n. Pinobius pedatus (Lea, 1923) is tentatively regarded as a synonym of P. alatus (Lea, 1923). Lectotypes are designated for Dolicaon adjacens Cameron, 1937, D. alatus Lea, 1923, D. indicus Kraatz, 1859, D. javanus Cameron, 1936, D. robustus Kraatz, 1859, D. sparsiventris Fauvel, 1886, and D. vicinus Kraatz, 1859. The revision revealed that the previously described species had largely been misinterpreted, suggesting that nearly all literature records other than original descriptions are based on misidentifications. Primarily based on the morphology of the aedeagus, the species are assigned to four species groups. The zoogeography of the genus in the study region is discussed. The Indian Subcontinent, eastwards to Myanmar, is the region with the greatest diversity. The distributions of all the species are mapped. The examined material was largely collected at light sources, partly also sifted from leaf litter, at low to intermediate elevations. Only one of the studied specimens is teneral. A key to species and a checklist of the Pinobius species of the Oriental, Palaearctic, and Australian Regions are provided. The genus now comprises a total of 35 species, ten in the Afrotropical, twenty in the Oriental, and seven in the Australian Region. Only five species, none of them exclusive, have been recorded from the south of the Palaearctic Region (southern Arabian Peninsula, South Himalaya, South China), one of them of Afrotropical and the other four of Oriental affiliations. In an appendix, a dolicaonine species from the Afrotropical Region is described: Jarrigeus verberans sp.n. (Nigeria).

(Pingbian env.) of the newly established N. semifissus group; N. fibulatus sp. n. (Kunming env.), N. bulbosus sp. n. (Kunming env.), N. clavilobatus sp. n. (Dongchuan env.), and N. conicus sp. n. (Xundian env.) of the N. cangicus group. Together with N. zhangi Watanabe & Xiao, 1993, the latter three species form a distinct lineage within the N. cangicus group. Two species remain unnamed, as they are represented exclusively by females. The general distribution of the genus in Yunnan and the individual distributions of the newly described species are mapped. Nazeris now includes a total of described 233 species (plus seven subspecies), 118 of which have been recorded from mainland China. The fauna of Yunnan currently comprises 45 described species.

The distributions of the Eccoptoglossa species are mapped and a key to species is provided.

424:
On the genus Crataraea (Coleoptera: Staphylinidae: Aleocharinae: Oxypodini). – Three species previously attributed to the Crataraea Thomson, 1858, subtribe Microglottina, are revised and illustrated. Only one of them, C. solskyi (Eppelsheim, 1888), is retained in the genus. Two species are moved to Aleochara Gravenhorst 1802: Aleochara (Xenochara) rubripennis (Fauvel, 1872), nov.comb., and A. (X.) eremita (Peyerimhoff, 1931), nov.comb. The previous synonym Aleochara rubripes Blatchley, 1910 is revalidated to replace the secondary junior homonym Aleochara rubripennis (Casey, 1906). A lectotype is designated for Crataraea rubripennis Fauvel, 1872. Crataraea now includes three species native in the Palaearctic region, with one species adventive in North America. A key to species is provided.

Three new species and additional records from Nepal and China (Coleoptera: Staphylinidae: Paederinae). – Three species of Nazeris Fauvel, 1873 are described and illustrated: N. brevior sp. n. (Nepal: Solu Khumbu) of the N. alticola group; N. hamulatus sp. n. (China: Shaanxi: Qinling Shan) of the N. longilobatus group; N. eminens sp. n. (China: Sichuan: Emei Shan), tentatively assigned to the N. zhangi lineage of the N. cangicus group. Additional records of eleven described and one unnamed species are reported from Nepal (four species) and China (eight species). The Palaearctic genus is now represented by 236 described species (plus seven subspecies), 120 of which are distributed in mainland China and 49 in the Himalaya.

453:
On the Staphylinidae of the Greek island Samos (Coleoptera: Staphylinidae). – A recent field trip to the Greek island Samos yielded 1322 specimens belonging to at least 117 species of Staphylinidae. Three species are described and illustrated: Geostiba (Tropogastrosipalia) plicipennis sp. n. (Oros Ambelos) and Oxypoda (Bessopora) kerkisica sp. n. (Oros Kerkis) of the Aleocharinae, and Sunius ambelosicus sp. n. (Oros Ambelos) of the Paederinae. Geostiba plicipennis is the first representative of the speciose subgenus Tropogastrosipalia Scheerpeltz, 1951 to be recorded from an island. Including the Pselaphinae and Scydmaeninae recorded by Volker Brachat and Heinrich Meybohm in 2003, as well as previous literature records, at least 136 species of Staphylinidae are currently known from Samos, 103 of them named and positively identified, 15 undescribed (five of the Pselaphinae and ten of the Scydmaeninae), eight tentatively identified, and at least ten unidentified. Six species are reported from Greece for the first time. The remarkably diverse staphylinid fauna of Samos includes as many as 18 species that have been recorded exclusively from this island and are most likely island-endemic, some of them even locally endemic. However, only seven of these species have been named; the remainder is pending description. Xantholinus chiosicus Assing, 2015, a species previously hypothesized to be endemic to Chios, is recorded also from Samos. The diversity of the staphylinid fauna of Samos is evidently greater than that of other North Aegean islands; it appears to be even greater than that of the much larger island Rhodes, an observation that may be explained with the geography, geology, and ecological characteristics of Samos. A comprehensive list of the named and unnamed species currently known from Samos is provided.

On the Staphylinidae of the Greek island Karpathos (Insecta: Coleoptera). – A study of 931 specimens of Staphylinidae collected in the Greek island Karpathos in December 2015 and January 2016 yielded 59 species, among them eight undescribed island-endemic species and three first records from Greece. A checklist including also previously recorded species is provided. The currently known fauna of Karpathos is composed of 69 species of Staphylinidae and shows stronger affinities to the fauna of Turkey and the Aegean islands off the Turkish coast than to Crete and mainland Greece (including the Pelopónnisos). Ten species (14.5 %) are island endemics, three of which (two of the Pselaphinae and one of the Scydmaeninae) are undescribed.

Nazeris clavator represents the first record of the genus from Guangdong province. Additional records of 23 described and one undescribed species are reported from the Caucasus, the Himalaya, Vietnam, and China. The genus now includes a total of 241 described species and seven subspecies. It is represented in China by 125 described species.

482:
On some Acanthoglossa and Hypomedon species II. Two new species, a new synonymy, and additional records (Coleoptera: Staphylinidae: Paederinae). – Two species of Hypomedon Mulsant & Rey, 1878 are described and illustrated: H. nasutus nov.sp. (Thailand) and H. bicornutus nov.sp. (Laos). Based on a study of types, the following synonymy is proposed: Acanthoglossa hirta Kraatz; 1859 = Medon sutteri Scheerpeltz, 1957 nov.syn. Records of Hypomedon debilicornis (Wollaston, 1857) and H. galilaeus (Bordoni, 1980) are reported, among them the first records of the H. galilaeus from Pakistan and Taiwan. The enormous range of this species, which now extends from the Middle East to Taiwan, is mapped. Unlike the populations from other regions, the material of H. galilaeus from Taiwan is brachypterous.

483:
On the Staphylinidae of the Greek island Lesbos II, with supplementary notes on the fauna of Samos and Chios (Coleoptera: Staphylinidae). – A field trip to the Greek island Lesbos conducted in spring 2016 yielded a total of 1640 specimens belonging to 169 species of Staphylinidae. Nine new species are described and illustrated: Myllaena lesbia Assing sp.n., Aloconota (Aloconota) aegaea Assing sp.n. (also recorded from Samos), and A. (A.) lesbia Assing sp.n. of the Aleocharinae, Sunius potti Assing sp.n. of the Paederinae, Bryaxis lesbius Brachat sp.n., Bythinus simplicipalpis Brachat sp.n., Protamaurops assingi Brachat sp n., and Tychus lesbius Brachat sp.n. of the Pselaphinae, and Stenichnus (Stenichnus) lesbius Meybohm sp.n. of the Scydmaeninae. The new species of Paederinae, Pselaphinae, and Scydmaeninae are most likely endemic to Lesbos. A comprehensive list of the named and unnamed species currently known from Lesbos is provided. Numerous described species are reported from the island for the first time, eight of them represent first records from Greece. The known staphylinid fauna of Lesbos currently includes 199 species, 184 named and 15 unnamed, unidentified, or tentatively identified. Nine (5 %) of the named species and at least two of the unnamed Pselaphinae and Scydmaeninae are hypothesized to be endemic to the island. Thus, despite greater overall diversity and a generally similar composition, the fauna of Lesbos includes fewer island endemics than that of the geographically close and significantly smaller island Samos. As was to be expected, the fauna of Lesbos displays close affiliations with that of the adjacent Turkish mainland. Several species reach their westernmost distribution limit in this island (some of them also in Chios and Samos). As many as six myrmecophilous species have been recorded from Lesbos, five of them associated with Messor spp. and one with Cataglyphis nodus (Brullé, 1833). In an appendix, Ocalea brachyptera Fagel, 1971 is reported from Chios, the first record of this species from Greece. Aloconota (Aloconota) samia Assing sp.n. (Samos) of the Aleocharinae and Stenichnus (Stenichnus) chius Meybohm sp.n. (Chios) of the Scydmaeninae are described and illustrated.

(South Armenia: environs of Jermuk). The type locality of G. carinicollis (Eppelsheim, 1878) is revised and G. medea Pace, 1996, previously a junior synonym of G. carinicollis, is revalidated. Additional records of G. bituberculata (Eppelsheim, 1878) and G. kobrisensis Pace, 1996 are reported, and previous records of G. kobrisensis are rectified. A key to the 17 Sibiota currently known from the Caucasus region exclusive of Turkey, all of them microphthalmous and micropterous, is provided. Their distributions are mapped.

485:

Available data on the zoogeography and natural history of the Anaulacaspis species recorded from the Palaearctic region are compiled. The distributions of the genus as a whole and of the individual species are mapped. A catalogue and a key to species are provided.

488:
On the taxonomy and zoogeography of the species of the Quedius paradisianus group (Coleoptera: Staphylinidae: Staphylininae). – The distributions of four species of the Quedius paradisianus group – Q. paradisianus (Heer, 1839), Q. italicus Gridelli, 1925, Q. collaris Erichson, 1840, and Q. rodopianus Coiffait, 1971 – are revised, mapped, and discussed. While Q. italicus, Q. collaris, and Q. rodopianus have discrete allopatric distributions, that of the widespread and common Q. paradisianus significantly overlaps with the ranges of the other three species. Several new country records are reported. Quedius italicus, previously a subspecies of Q. collaris, is regarded as a distinct species. Lectotypes are designated for Philonthus paradisianus Heer, 1839 and Quedius collaris Erichson, 1840. A key to species and illustrations of relevant diagnostic characters are provided. Data on the natural history are compiled. The vertical distribution and/or the phenology of three species are illustrated.

(Malaysia: Sabah); Drusilla lativentris sp. n. (China: Yunnan); Rabdotodrusilla vara sp. n. (India: Meghalaya); Witteia tensa sp. n. (China: Yunnan). The following new combination and synonymy are established: Pheidologitonetes adesi (Pace, 1998), comb. n. (ex Zyrastilbus); Drusilla obliqua (Bernhauer, 1916) = D. palata Assing, 2015, syn. n. Zyrastilbus angkorensis Pace, 2004 is not congeneric with the type species of Zyrastilbus Cameron, 1939; its correct generic assignment (Drusilla?) is currently unknown.  An updated catalogue of the 174 described representatives of Orphnebius Motschulsky, 1858 in the East Palaearctic and Oriental regions is provided; the species are grouped according to a recently proposed intrageneric system. Amaurodera Fauvel, 1905 currently includes 53 described species distributed in the southern East Palaearctic and the Oriental regions. Additional records of 46 named and three unnamed species are reported, among them several new country records. The distributions of two Himalayan Orphnebius species are mapped..

Zyras novinversus nom. n. is proposed for the preoccupied name Z. inversus Pace, 2012, syn. nov. Lectotypes are designated for Zyras exasperatus Schubert, 1908, Z. drescheri Cameron, 1939, Z. gratellus Cameron, 1939, Myrmedonia perforata Champion, 1921, and Hygroptera castanea Motschulsky, 1861. Remarkable cases of colour polymorphism and of sexual dimorphism are discussed. A key to the Zyras sensu strictu species of the Himalaya, India, and Sri Lanka, a key to the species recorded from Thailand, and an updated catalogue of the Zyras sensu strictu species of the Palaearctic and Oriental regions are provided. Additional records of numerous named and several unnamed species are reported. The revised distributions of 37 species are mapped. The subgenus is currently represented in the Palaearctic and Oriental regions by a total of 124 described species. The countries with the greatest diversity are China (46 named species), Malaysia (20), India (20), Indonesia (18), Thailand (13), and Nepal (12). The subgenus is reported from Sulawesi for the first time (five named and two unnamed species). Based on a revision of type material, eleven species are not included in, or excluded from, Zyras sensu strictu, and Zyras unicolor Cameron, 1939 is tentatively moved to Drusilla Leach, 1819..

491:
On the Staphylinidae of the Greek island Kos, with an appendix on Carabidae and additional records from other islands (Insecta: Coleoptera). – A study of 567 specimens of Staphylinidae collected in the Greek island Kos in April 2012 and December 2016 yielded 54 species, among them five first records from Greece. One of them is Quedius curtidens Smetana, 1967, a species previously known only from Adana province (Turkey) and also reported from Lebanon, Syria, and Israel for the first time; its distribution is mapped. A checklist of the species recorded from Kos is provided. The known staphylinid fauna is represented by 58 species and shows strong affinities to the fauna of the close Turkish mainland. It is primarily composed of widespread West Palaearctic (40 %), East Mediterranean (36 %), South Anatolian (11 %), or widespread Mediterranean (8 %) species. In an appendix, records of 15 species are reported from Cyprus, Rhodos, Samos, and Lesbos. Moreover, 29 species of Carabidae (177 specimens) are reported from Kos; eight of these species are recorded from the Aegean Islands for the first time.

492:
On Quedius coloratus Fauvel, 1875 and allied species, with an appendix on Quedius species collected in Greece iwth subterranean pitfall traps, and a new synonymy (Coleoptera: Staphylinidae: Staphylininae). – A revision of material previously identified as Quedius coloratus Fauvel, 1875 revealed that it is composed of at least five species: Q. (Raphirus) coloratus (Middle East); Q. (R.) hellenicus nov.sp. (Greece); Q. (R.) hebes nov.sp. (South Anatolia); Q. (R.) spiculatus nov.sp. (North Anatolia); Q. (R.) carpathius nov.sp. (Karpathos). These species, as well as one male possibly representing a sixth species (Greece: Thessalía) are described and illustrated. Available evidence suggests that their habitats are subterranean and their distributions are allo- or parapatric. All the named species are presumably capable of flight. A key to species is provided. In an appendix, additional records of three Quedius species collected in Greece with subterranean pitfall traps are reported. One of these species is reported from Greece for the first time. The distributions of the species allied to Q. coloratus, of Q. (Microsaurus) bernhaueri Rambousek, 1915, and of Q. (Raphirus) endogeus Assing, 2007 are mapped. Quedius endogeus, a species previously known only from two localities, is widespread in Greece and evidently a true inhabitant of the "Superficial Subterranean Habitat" (MSS stratum). Quedius crnagoricus Coiffait, 1980, nov.syn., is placed in synonymy with Q. paradisianus (Heer, 1839).

493:
A revision of the Alevonota species of the Palaearctic region. II. A new species from Cyprus and additional records (Coleoptera: Staphylinidae: Aleocharinae). – Alevonota flexa nov.sp. (Cyprus) is described and illustrated. Additional records of four species are reported, among them several new country records. Alevonota japonica (Cameron, 1933), a species with a remarkable sexual dimorphism of head shape and eye size, is illustrated, based on new material from Hokkaido.

494:
Taxonomic and faunistic notes on some West Palaearctic and Middle Asian Xantholinini, with a revalidation and new synonymies (Coleoptera: Staphylinidae: Staphylininae). – Xantholinus motschulskyi Bordoni, 1999, previously a synonym of X. reitteri Coiffait, 1966, is revalidated. The internal structures of the aedeagus of X. motschulskyi, X. reitteri, and X. corallinus Reitter, 1901 are illustrated. A lectotype is designated for X. corallinus. Six synonymies are proposed: Gyrohypnus punctulatus (Paykull, 1789) = Gyroyhypnus quadratus Stephens, 1833, nov.syn.; Stenistoderus cephalotes cephalotes (Kraatz, 1858) = S. cephalotes armeniacus (Coiffait, 1966), nov.syn.; Xantholinus linearis (Olivier, 1795) = X. styriacus Grimmer, 1841, nov.syn.; X. gridellii Coiffait, 1956 = X. tronqueti Bordoni, 2016, nov.syn.; X. khnzoriani Coiffait, 1966 = X. caucasicus Bordoni, 1975, nov.syn., = X. iablokoffi Coiffait, 1975, nov.syn. A neotype is designated for Gyroyhypnus quadratus Stephens, 1833. New records of 37 species of Xantholinini are reported. The revised distributions of X. reitteri and X. motschulskyi are mapped.

495:
Two new species and additional records of micropterous Paederus from China and Taiwan (Coleoptera: Staphylinidae: Staphylininae). – Two species of Paederus Fabricius, 1775 from China and Taiwan are described and illustrated: Paederus (Gnathopaederus) furcillatus nov.sp. (China: Guizhou) and P. (Megalopaederus) nigricrus nov.sp. (Taiwan: Taitung Hsien). Additional records of eight species of Harpopaederus Scheerpeltz, 1957 (two species), Gnathopaederus Chapin, 1927 (one species), Megalopaederus Scheerpeltz, 1957 (three species), and of the P. biacutus group (two species) are reported. The genus is currently represented in China and Taiwan by 51 and 25 species respectively.

496:
A revision of Leptobium Casey. VIII. A new species from Iran, a new synonymy, and additional records (Coleoptera: Staphylinidae: Paederinae). – Leptobium iranicum nov.sp. (Iran: Yazd province) is described and illustrated. One synonymy is proposed: Leptobium carinatum Assing, 2005 = nabozhenkoi Anlaş, 2012, nov.syn. Additional records of 25 species and subspecies are reported. The genus now includes a total of 67 species and two subspecies.

497:
Four new species and additional records of Lathrobium from Nepal and China (Coleoptera: Staphylinidae: Paederinae). – Four species of Lathrobium Gravenhorst, 1802 are described and illustrated: Lathrobium kongmaicum nov.sp. (East Nepal: Kongma Danda), L. latilobatum nov.sp. (East Nepal: Kongma Danda), and L. paulitortum nov.sp. (East Nepal: Solu Khumbu) of the L. nepalense group, and L. piraticum nov.sp. (China: Sichuan: Wolong) of the L. fissispinosum group. Additional records of three species from China and three species from Nepal are reported, among them the first recent records of L. nepalorientis Coiffait, 1984 and L. khumbuense Coiffait, 1982. The genus is now represented in the Palaearctic region by 595 species and nine subspecies. The Himalayan fauna currently includes 76 described species, all of them micropterous and locally endemic. As many as 220 named species have been recorded from China.

498:
A revision of Palaearctic Lobrathium. VI. Two new species from Armenia and Taiwan, and additional records (Coleoptera: Staphylinidae: Paederinae). – Two species of Lobrathium Mulsant & Rey, 1878 are described and illustrated: L. ancoriferum nov.sp. (Armenia) and L. biuncinatum nov.sp. (Taiwan). Additional records of 13 species are presented.

499:
A revision of Palaearctic Nazeris IX. Three new species from Nepal and additional records (Coleoptera: Staphylinidae: Paederinae). – Three species of Nazeris Fauvel, 1875 of the N. flavocaudatus group from East Nepal are described and illustrated: Nazeris biapicalis nov.sp., N. hebes nov.sp., and N. trapezilobus nov.sp. Additional records of three previously described species are reported from East Nepal and Lebanon. The pronounced intraspecific variation of external and sexual characters of N. ammonita (Saulcy, 1865) is discussed and illustrated. The genus now includes a total of 250 described species and seven subspecies. It is represented in the Himalaya (exclusive of China) by 52 described species.

500:
A revision of Neosclerus Cameron VI. Thre new species from India, Thailand, and Vietnam (Coleoptera: Staphylinidae: Paederinae). – Three species of Neosclerus Cameron, 1924 are described and illustrated: N. anguliceps nov.sp. (South India), a species of uncertain affiliations, N. concavus nov.sp. (Thailand) of the N. brevispinosus group, and N. vietnamensis (Vietnam) of the N. brevispinosus group. The latter species represents the second record of the genus from Vietnam. Including the new species, the genus now includes 47 species distributed in the southern East Palaearctic and Oriental regions.

501:
The first species of Chinecallicerus from Sichuan, China (Coleoptera: Aleocharinae: Geostibini). – Chinecallicerus pinnatus nov.sp. (China: Sichuan: Wolong), the first representative of the genus to be recorded from outside Yunnan, is described, illustrated, and distinguished from its congeners. An updated key to the species of Chinecallicerus Assing, 2004 is provided. The genus currently includes seven species, six of which are representely solely by their respective holotypes.

502:
A revision of types and additional material of Staphylinidae from the Iablokoff-Khnzorian collection (Insecta: Coleoptera). – Types and additional material from the Iablokoff-Khnzorian collection are revised. The following synonymies are proposed: Olophrum puncticolle Eppelsheim, 1880 = O. erevanicum Iablokoff-Khnzorian, 1964, nov.syn.; Astenus procerus (Gravenhorst, 1806) = Astenus silvicola Iablokoff-Khnzorian, 1961, nov.syn.; Myrmoecia reitteri (Eppelsheim, 1881) = Zyras argus Iablokoff-Khnzorian, 1960, nov.syn.; Aleochara (Xenochara) rambouseki Likovský, 1964 = A. addenda Likovský, 1981, nov.syn., = A. hamulata Assing, 2009, nov.syn. The holotypes of Rugilus armeniacus (Coiffait, 1970), Aleochara polychroma Iablokoff-Khnzorian, 1966, and A. nobilis Likovský, 1965 are illustrated. The latter is moved to the subgenus Xenochara Mulsant & Rey, 1874 (ex Heterochara Mulsant & Rey, 1874). Seven species of Staphylinidae are reported from Armenia and one from Slovenia for the first time. The record of one species from Armenia is based on a misentification.

503:
On some Athetini from Armenia and adjacent regions (Coleoptera: Aleocharinae). – Nine species of Athetini from Armenia are described and illustrated, eight of them for the first time: Atheta (Atheta) brevapicalis nov.sp. (South Armenia); A. (A.) hamulata nov.sp. (South Armenia); A. (Dimetrota) bispinosa nov.sp. (Armenia, Georgia); A. (D.) senticollis nov.sp. (North Armenia); A. (Oreostiba) altiviva Benick, 1974 (widespread in Armenia); A. (O.) semialba nov.sp. (widespread in Armenia); A. (O.) abscisa nov.sp. (widespread in Armenia); A. (O.) brevitheca nov.sp. (widespread in Armenia); Liogluta armeniaca nov.sp. (Central and South Armenia). Three synonymies are proposed: Atheta hansseni Strand, 1943 = A. brachati Assing, 2013, nov.syn.; Liogluta granigera (Kiesenwetter, 1850) = L. trigemina (Eppelsheim, 1880), nov.syn.; L. funesta Eppelsheim, 1890 = L. nigrobusta Assing, 2016, nov.syn. A lectotype is designated for Homalota trigemina Eppelsheim, 1880.

504:
On Stilicoderus VI. Two new species from South Vietnam and additional records (Coleoptera: Paederinae). – Two species of Stilicoderus Sharp, 1889 from South Vietnam are described and illustrated: Stilicoderus bisinuatus nov.sp. of the S. granulifrons group and S. harpago nov.sp. of the S. discalis group. Additional records of five species are reported, among them a new record from Bhutan. The genus now includes a total of 113 species.

506:
A revision of Nazeris X. The first record of the genus from South Vietnam and additional records from Thailand (Coleoptera: Staphylinidae: Paederinae). – Nazeris raptus nov.sp. from South Vietnam is described and illustrated. This record is of special zoogeographic significance, as it is situated nearly 6.5 degrees of latitude farther south than the previous southernmost record of the genus as a whole, thus casting doubt on the previous classification of the distribution of Nazeris Fauvel, 1873 as essentially South Palaearctic. Additional records of two species from Thailand are reported. An updated map illustrating the distribution of the genus as a whole is provided. Including the new species, Nazeris now includes 255 described species and seven subspecies.

507:
Two new species of Gnathymenus from Ecuador (Coleoptera: Staphylinidae: Paederinae). – Two species of the dolicaonine genus Gnathymenus Solier, 1849 from Ecuador are described and illustrated, Gnathymenus arboreus nov.sp. and G. spinifer nov.sp., both of them macropterous and collected by canopy fogging in the same locality in Pastaza province. The genus now includes 77 species, 16 of which are known from Ecuador. Additional records of Gnathymenus apterus Solier, 1849 are reported from Chile.

508:
On the micropterous Quedius (Raphirus) species with a punctate scutellum of Turkey (Coleoptera: Staphylinidae: Staphylininae). – Four micropterous species of Quedius Stephens, 1829, subgenus Raphirus Stephens, 1829, with a punctate scutellum are reported from North Turkey, one of them unidentified. Quedius brevalatus nov.sp. (Armenia; Turkey: Rize) is described and illustrated. Quedius omissus Coiffait, 1977, a species previously known only from the West Caucasus, is reported from Turkey (Rize) for the first time. Three synonymies are proposed: Quedius boops (Gravenhorst, 1802) = Philonthus boops tauricus Nordmann, 1837, nov.syn., = Quedius crius Tottenham, 1948, nov.syn. (previously a synonym of Q. reitteri Gridelli, 1925), = Quedius boops islandicus Fagel, 1960, nov.syn.

509:
A mass dispersal event of Quedius hellenicus (Coleoptera: Staphylinidae: Staphylininae). – In spring 2017, a mass dispersal event of Quedius hellenicus Assing, 2017, the first observation of such a behaviour in the genus, was witnessed in the Greek island Corfu. Additional evidence is presented suggesting that Q. hellenicus inhabits a subterranean habitat and that this most likely also applies to other representatives of the Q. coloratus group.

510:
On the Leptusa fauna of the Caucasus region (Coleoptera: Staphylinidae: Aleocharinae). – Five species of Leptusa Kraatz, 1858 from Georgia and North Iran are described and illustrated: L. (Neopisalia) substricta nov.sp. (Georgia: Shida Kartli); L. (N.) svanetica nov.sp. (Georgia: Svaneti); L. (N.) migrituber nov.sp. (Georgia: Svaneti); L. (N.) triangulata nov.sp. (Georgia: Adjara); L. (N.) longalata nov.sp. (Iran: Mazandaran). The genus is represented in the Caucasus region including Northeast Turkey (from Ordu to the border with Georgia), Georgia, Armenia, Azerbaijan, and the Russian part of the Greater Caucasus by 39 species in five subgenera; 28 species, two of them of doubtful identity, belong to the subgenus Neopisalia Scheerpeltz, 1966. Three zoogeogeographically implausible or revised previous records are rectified. Leptusa kaszabi Pace, 1981 is moved from the subgenus Heteroleptusa Pace, 1989 to Neopisalia. A zoogeographic study of the Leptusa fauna of the Caucasus region revealed that locally endemic species are confined to the moister western half of the region eastwards approximately to 43°30' eastern longitude. Moreover, little is known about the fauna of Abkhazia, which probably hosts an unknown number of unnamed species. A catalogue of the Leptusa species of the Caucasus region and maps illustrating the currently known distributions of 33 species are provided. Additional records of 19 described species are reported, among them several new country records.

511:
On the Geostiba fauna of Armenia (Coleoptera: Staphylinidae: Aleocharinae). – Three microphthalmous species of the subgenus Sibiota Casey, 1906, genus Geostiba Thomson, 1858, from Armenia are described and illustrated: Geostiba (Sibiota) tigrani nov.sp. (North Armenia: mountains to the north of Sevan lake); G. (S.) kalavanica nov.sp. (North Armenia: Kalavan mountain near the northwestern tip of Sevan lake); G. (S.) immutata nov.sp. (South Armenia: Barkushati range). Geostiba (Geostiba) sororcula Assing, 2001, a species previously known only from Northeast Turkey, is reported from Armenia for the first time. Like its close relative, the widespread G. circellaris (Gravenhorst, 1806), this species is wing-dimorphic. At present, the known Geostiba fauna is composed of nine described species in three subgenera; one or two additional species are unnamed (males unavailable). Seven described and the unnamed species, all of them microphthalmous, micropterous, and more or less locally endemic, belong to the subgenus Sibiota; they are subject to remarkable intraspecific variation of the male secondary sexual characters. A key to species and distribution maps are provided.

512:
A revision of Geostiba of the West Palaearctic region. XXV. New species from Georgia and Greece, and additional records (Coleoptera: Staphylinidae: Aleocharinae). – Four species of Geostiba Thomson, 1858 from Georgia and Greece are described and illustrated: Geostiba (Tropogastrosipalia) xirosica nov.sp. (Greece: Evvoia); G. (T.) svanetica nov.sp. (Georgia: Svaneti); G. (T.) gibberiventris nov.sp. (Georgia: Mtskheta-Mtianeti); G. (Sibiota) granisuturalis nov.sp. (Georgia: Svaneti). Additional records of seven species are reported. The distributions of the eight species of the subgenus Tropogastrosipalia Scheerpeltz, 1951 recorded from the Caucasus region, those of the nine species of Sibiota Casey, 1906 known from the West and Central Greater Caucasus, and the distribution of G. (Chondridiosipalia) cingulata (Eppelsheim, 1878) in the Caucasus region are mapped. Supplements to recently published keys to the Geostiba fauna of the West Palaearctic region are provided.

513:
On the Ischnosoma fauna of Georgia (Coleoptera: Staphylinidae: Tachyporinae). – Three species of the Ischnosoma spelaeum group are described and illustrated, all of them most likely with very restricted distributions: Ischnosoma acutum spec. nov. (Georgia: Svaneti, Racha); I. barbigerum spec. nov. (Georgia: Svaneti); I. molle spec. nov. (Georgia: Adjara). Type material of I. major (Luze, 1901) and I. caucasicum Kocian, 1997 is revised. Additional records of previously described species of Ischnosoma Stephens, 1829 are reported from Georgia, partly also from other regions. Seven species of the genus have reliably been recorded from Georgia, two species of the I. pictum group and widespread, five of the I. spelaeum group and with restricted distributions. The presence of an additional species of the I. spelaeum group, I. caucasicum, requires confirmation. The distributions of the species of the I. spelaeum group are revised and mapped. Several previous literature records are zoogeographically implausible and consequently probably erroneous.

514:
On the Zyras sensu strictu in the East Palaearctic and Oriental regions III, with a focus on the Southeast of Continental Asia and the Sunda Islands (Coleoptera: Staphylinidae: Aleocharinae: Lomechusini). – Species of the nominal subgenus of the lomechusine genus Zyras Stephens, 1835 of the southeastern Oriental region are revised. Eighteen species are (re-)described and/or illustrated, six of them for the first time: Zyras (Zyras) latibasalis spec. nov. (Java, tentatively recorded also from Laos), Z.

On the Staphylinidae of the Greek island Corfu (Insecta: Coleoptera). – A study of nearly 10,000 specimens of Staphylinidae collected in the Ionian island Corfu, Greece, in late spring 2017 yielded more than 233 species. Additional, previously unpublished records of 66 named species are reported from the island. Two species are described and illustrated: Borboropora corcyrana Assing spec. nov. of the Aleocharinae and Ocypus corcyranus Assing spec. nov. of the Staphylininae. As many as 118 named species are reported from Corfu for the first time, 21 of these species represent first records from Greece. One name is revalidated and six names are synonymized: Euplectus jonicus Meggiolaro, 1966 (revalidated) = E. jonicus corcyreus Meggiolaro, 1966, syn. nov.; Mycetoporus punctipennis Scriba, 1868 = M. insulanus Luze, 1901, syn. nov.; Anotylus tetracarinatus (Block, 1799) = A. corcyranus (Coiffait, 1968), syn. nov.; Bledius corniger Rosenhauer, 1856 = B. bubalus Gistel, 1857, syn. nov.; Paederus littoralis Gravenhorst, 1802 = P. pelikani Reitter, 1884, syn. nov.; Leptacinus batychrus (Gyllenhal, 1827) = Phacophallus corcyranus Bordoni, 2017, syn. nov. Including reliable previous literature records and the new records reported in the present paper, 446 named species (plus additional unnamed species) are currently known from Corfu. Thus, the known fauna of this island is significantly more diverse than those of other East Mediterranean islands, including the much larger Cyprus. A checklist of the Staphylinidae fauna of Corfu is provided. Although at present 18 species and subspecies have been recorded exclusively from Corfu, most of them are unlikely to represent island endemics; three of these species are of doubtful taxonomic status.
