Kurbatov, Sergey A., Kovalev, Alexey V. (2022): A new species of the genus Dendrolasiophilus Nomura, 2010 from the south of the Russian Far East (Coleoptera, Staphylinidae, Pselaphinae). Zootaxa 5100 (2): 296-300, DOI: https://doi.org/10.11646/zootaxa.5100.2.9

The genus Anelastes Kirby, 1819 of the Palaearctic fauna is revised. An amended diagnosis of the genus is elaborated. Two new species from North Africa, Anelastes abbreviatus sp. nov. and A. alius sp. nov. are described. Anelastes barbarus P.H. Lucas, 1846 and A. crenulatus (Bonvouloir, 1875) are redescribed and the lectotypes of both species are designated. A key to the Palaearctic species is provided. Anelastes barbarus is newly recorded from Uzbekistan.

A new genus of the family Drilidae, Drilorhinus gen. nov. with one new species D. klimenkoi sp. nov. from the South-West Iran (Lorestan) is described, illustrated and compared with all known genera of this group. The new genus differs from all members of the family in the strong projection of the anterior part of the frons between antennal insertions. Some problems of taxonomic rank and classification of Drilidae are considered.

A new genus of the family Brachypsectridae with two new species, Asiopsectra luculenta gen. et sp. n. (type species) from the Middle East (Iran) and A. mirifica sp. n. from Middle Asia (Tajikistan) are described. The genus Asiopsectra gen. n., in contrast to the genus Brachypsectra, is characterized by the 12-segmented bilamellate antennae, the very large and subcontiguous antennal fossae, the strongly raised supra-antennal keels, the very narrow mandibles, the presence of small “window” punctures on the elytra, the lack of keels along the posterior pronotal angles, and only a small patch of excretory hairs at the posterior edge of abdominal ventrite 5. A revised diagnosis for the family Brachypsectridae is given.

Allenipeplus gen. nov. represented by A. philippinensis sp. nov., type species (Philippines, Luzon), A. alius sp. nov. (Philippines, Mindoro), A. harmonicus sp. nov. (Philippines, Mindanao) and A. vitellinus sp. nov. (Indonesian New Guinea), is described. This new genus combines characters with a mosaic spread among other cillaeine genera. We present a wide comparison of genera among the subfamily Cillaeinae, making it possible to elaborate a detailed diagnosis of the new genus and trace some order in character patterns and propose a hypothesis on the relationship of this genus to other groups known from the Indo-Malayan and Australian Regions. A detailed diagnosis of the new genus and key to the new species are given. The Adocimus-complex of the related genera including Allenipeplus gen. nov., Adocimus Murray, 1864, Ithyphenes Murray, 1864, Platynema Ritsema, 1885 and probably Brittonema Kirejtshuk, 2011 is defined. Some notes on the taxonomy of the genera Liparopeplus Murray, 1864 and Xanthopeplus Fairmaire, 1880, stat. nov. are given. Additionally, designation of a lectotype for Liparopeplus colastoides Murray, 1864 is made.

Caledomus extraordinarius gen. et sp. nov. of the subfamily Cillaeinae is described from New Caledonia (Tinchialit). This new genus is a member of the Adocimus-complex of genera. The new name Brittonoma nom. nov. is proposed for the junior homonym Brittonema Kirejtshuk, 2011, non Thorne, 1967.

The genus Calycina Blair, 1922 (Mordellinae, Mordellini) is one of the most fascinating and enigmatic genera of Mordellidae. The genus exhibits a pantropical distribution: one species with two subspecies in South America (Horak 1999; Leblanc 2013), one species in Africa (Horak 1999), three species in Southeast Asia (Horak 1999) and two species in the Papuan Region (Horak 1999; Ruzzier 2013). All species are known from only a few specimens, almost exclusively females, and appear to be generally very rare. Only Calycina major Nomura, 1967 and Calycina nigroapicalis Nomura, 1967 reach the Palearctic Region (Horak 2008; Ruzzier 2013) and no other species have been recorded from higher latitudes. The opportunity to study specimens from the Primorye region (Russian Far East) allowed the authors to identify a new species that is described below.

The distribution of the genus Stenelmis (Elmidae) of the Caucasus is reviewed based on materials collected by the authors and examined specimens stored in accessible collections. One of the two species present in this region, represented by the subspecies Stenelmis consobrina consobrina Dufour, 1835, is recorded for the first time in Krasnodar Krai and possibly in Armenia; Stenelmis puberula Reitter, 1887 is recorded for the first time in Russia (Krasnodar Krai and the Republic of Adygea) and Abkhazia.
