Glotov, S. V. — Gyrophaena anastasiarum Glotov, sp. n. is described from Primorskiy Kray (Russian Far East). New synonymy is proposed: Gyrophaena triquetra Weise, 1877 = Gyrophaena fl ammula Pace, 2007 syn. n. Lectotypes are designated for Gyrophaena hanseni A. Strand, 1946, G. korbi A. Strand, 1939, G. munsteri A. Strand, 1935, G. pseudonana A. Strand, 1939, G. semipunctata Bernhauer, 1926, and G. transversalis A. Strand, 1939. Gyrophaena kaunshanchiensis Pace, 2007 is recorded from Russia (Primorskiy Kray) for the fi rst time. K e y w o r d s : Coleoptera, Staphylinidae, Aleocharinae, Gyrophaena, taxonomy, Russia, Taiwan. Introduction Th e rove beetle genus Gyrophaena Mannerheim, 1830 includes 721 described species in the world fauna (Newton, 2022). Of these, 193 species are known from the Palaearctic Region (Schülke & Smetana, 2015). Larvae and adult Gyrophaena are obligate fungivores feeding on mature spores, basidium, or fungal hyphae, scraping spores off the surface of the fungal hymenium (Ashe, 1984). Several species can form mass aggrega- tions in one fungal body, and particular species are repeatedly found together in one complex of co-existing species. Some species of Gyrophaena demonstrate associations with particular species of fungi (Ashe, 1984; Seevers, 1951). Th ough oft en very similar in external characters, the species are readily separated based on the form of male tergite VIII and morphology of the aedeagus, which is usually relatively large and distinc- tive. A reliable identifi cation of females, however, is oft en diffi cult. Th e present paper is based on examina- tion of material of both sexes from numerous institutional and private collections, including one previously unknown species; in addition, new synonymies are established and numerous new records of zoogeographi- cal interest are provided.

Based on the similar morphology of the male primary and sec- ondary sexual characters, Gyrophaena anastasiarum Glotov, sp. n. is similar to G. triquetra Weise, 1877 and allied species, G. bucranium Pace, 2007 and G. monstruosa Pace, 2007. It can be reliably distinguished from these species by the shape of the male sternite VIII and ae- deagus. For illustrations of the aedeagi of G. bucranium and G. monstruosa see Pace (2007).

Th e original description of G. plutenkoi is based on a single holotype from “Russia, Primorsky Kray” collected by A. Plutenko (Glotov, 2014). In the origi- nal description, the species was not assigned to any subgenus, which has caused some confusion and in the catalog of the Palearctic (Schülke & Smetana, 2015), rendering it a “species incertae sedis”. According to external morphological features, including: the shape and proportions of the length and width of the head, which is strongly transverse, the size and nature of the convexity of the eyes, and the nature of the narrowing of the head behind the eyes, as well as the shape of aedeagus, the species can be placed in the subgenus Gyrophaena.

Female: posterior margin of tergite VIII rounded, without incision or appendages (fi g. 1, 10). Aedeagus (fi g. 2, 9). D i s t r i b u t i o n . Japan, North Korea, Taiwan. C o m m e n t s . Th e original description of G. triquetra is based on an unspecifi ed num- ber of syntypes collected “an Baumschwämmen bei Hagi (Japan)” collected by J. Weise (Weise, 1877). Male and female syntypes were found in the collection of MNHB. Th e des- ignation of the male specimen as lectotype is done for the better fi xation of the identity of the name Gyrophaena triquetra Weise, 1877. Th e original description of G. sunanica is based on a holotype male from “Korea, Sŏkam, distr. Sunan, prov. Phjongan-namdo (North Korea)” and 16 paratypes (5 { and 11 }) same data and place as in holotype, collected by “R. Bielawski et M. Mroczkowski” (Paśnik, 2001). Male and female paratypes were found in the collections of ISEA and MIZ. Paśnik (2001) compared it to G. futamata (Cameron, 1933), but there was no reference whatsoever to G.  triquetra; the fi gures of the aedeagus of the holotype and paratype of G. sunanica in Paśnik (2001) are rather misleading. An examination of the holotype and paratypes revealed that it is identical of G. triquetra in external characters, as well as in the shape of the male sternite VIII and in the morphology of the aedeagus. Examination of the holotype and paratype of G. sunanica revealed that they belong to G. triquetra. I consider G. sunanica to be a junior synonym of G. triquetra. Th e original description of G. fl ammula is based on the male holotype from “Kaoh- siung Hs. for abv. Tona For. Sta. 1100 m (Taiwan)” collected by A. Smetana (Pace, 2007). Th e holotype was found in the collection of MSNV. Pace (2007) compared G. fl ammula to G. taiwaspinosa Pace, 2007, but not to G. triquetra; the fi gures of the aedeagus of the holo- type and paratype of G. fl ammula in Pace (2007) are rather misleading. An examination of the holotype G. fl ammula revealed that it is identical to G. triquetra in external characters, as well as in the shape of the male sternite VIII and in the morphology of the aedeagus. Th e synonimy of G. sunanica as a junior synonym of G. triquetra was already established before (Kim & Ahn, 2010). I also consider G. sunanica to be a junior synonym of G. triquetra. I thank J.
