Abstract. A brief review of the genus Cryphaeus Klug, 1833 of the Russian Far East is given. Two species occur in this region: C. amurensis (Heyden, 1884) in the Primorsky and Sakhalin regions and C. albopilosus Chûjô et Lee, 1993 in the Primorsky Region (new record for Russia). A new synonymy is proposed: Cryphaeus amurensis (Heyden, 1884) = Anthracias duellicus Lewis, 1894, syn. n. Cryphaeus amurensis was described by Heyden in 1884, but not by Kulzer, 1950 as indicated in the Catalogue of Palaearctic Coleoptera, 2008.

Резюме. Дан краткий обзор рода Cryphaeus Klug,

1833 российского Дальнего Востока. В этом регионе встречаются 2 вида: C. amurensis (Heyden, 1884) в Приморском крае и на Сахалине и C. albopilosus Chûjô et Lee, 1993 в Приморском крае (новый вид для фауны России). Предложена новая синонимия: Cryphaeus amurensis (Heyden, 1884) = Anthracias duellicus Lewis, 1894, syn. n. Cryphaeus amurensis был описан Хейденом (Heyden) в 1884 году, а не Кюлцером (Kulzer) в 1950, как указано в каталоге палеарктических жесткокрылых 2008 года.

A checklist of the tenebrionid fauna of Russia is continuously updated and presently includes 277 species from 117 genera [Nabozhenko, 2018]. The most intensive studies were recently carried out in the Russian Far East. Two new species from the genera Nalassus Mulsant, 2015 and Toxicum Latreille, 1802 were described and a new Platydema Laporte et Brullé, 1831 was recorded from the Primorsky Region of Russia for the first time [Nabozhenko, Ivanov, 2015, 2018; Ivanov et al., 2017]. Below we give information about a new record of the genus Cryphaneus Klug, 1833 from this Russian region.

The genus Cryphaeus comprises three species in the faunaof Russia. Cryphaeuscornutus (Fischervon Waldheim, 1823) is distributed in Southern Europe, Crimea, Rostov, Volgograd, Krasnodar and Stavropol regions of Russia and in the Caucasus [Abdurakhmanov, Nabozhenko, 2011]. The second species, Cryphaeus amurensis Heyden, 1884 is listed as an endemic species from the Russian Far East [Medvedev, 1992; Löbl et al., 2008]. The third species of this genus, Cryphaeus albopilosus Chûjô et Lee, 1993, which was described from the Korean Peninsula, is newly found in the Primorsky Region of Russia.

This study is based on specimens from the Staatliches Museum für Naturkunde (SNMS, Stuttgart, Germany), the private collection of M.V. Nabozhenko (CN, Rostov- on-Don, Russia) and collected material of E.V. Komarov (Volgograd, Russia).

(Figs 1–5)

Material. 1♀ (CN), Russia, Primorsky Region, Khasan District, Baburovo, 19.07.1990 (leg. A. Napolov); 1♂, 1♀ (CN), Russia, Primorsky Region, Terney Distr., near Artemovo, floodplain of Serebryanka River, 15.05.2015 (leg. M.E.

Distribution. Russia: Primorsky Region, Southern Sakhalin [Medvedev, 1992; Kompantseva, 1999]. China (Hainan), Taiwan, Korean Peninsula, Japan [Löbl et al., 2008].

Notes. Cryphaeus amurensis was described by Heyden [1884: 295] from Vladivostok (Russia) and is erroneously listed with the authorship of Kulzer [1950] in

the Catalogue of Palaearctic Coleoptera [Löbl et al., 2008].

Notes on the taxonomy and distribution of the genus Cryphaeus Klug, 1833 (Coleoptera: Tenebrionidae: Toxicini) 179


Chinese colleagues recorded C. amurensis for China, but without supporting material or cited literature of collected specimens [Wu, Ren, 2008]. Cryphaeus duellicus was described by Lewis from Japan (“Yuyama, Kadzusa, Niigata, and Junsai”) in the genus Anthracias [Lewis, 1894] and was later listed for the Korean Peninsula [Mochizuki, Tsumekawa, 1937; Jung et al., 2009], Russian Far East, China (Hainan) [Löbl et al., 2008; Wu, Ren, 2008; Jung et al., 2009] and Taiwan [Jung et al., 2009].

Both taxa are conspecific as shown by having several common characteristics such as the 3-segmented antennal club, the head with triangularly produced anterior corners of the male frontoclypeus, the similar form of supraorbital horns, elytral striae with geminate irregular rows of punctures (especially in the middle of elytra), strongly convex interstriae, and the similar form of aedeagi. Therefore a new synonymy is proposed: Cryphaeus amurensis (Heyden, 1884) = Anthracias duellicus Lewis, 1894, syn. n.

Bionomics. Larvae and adults inhabit the polypore

mushrooms Trametes sp., Irpex lacteus [Kompantseva, 1999], Daedaleopsis congragosa and D. tricolor [Jung et al., 2009].

Cryphaeus albopilosus Chûjô et Lee, 1993 (Fig. 6)

Material. 1♂ (SMNS), China, Shaanxi Prov., Taibai Shan above Houshenzi, 1300–1700 m, 9.06–3.07.1998 (leg. P. Jäger, J. Martens); 1♀ (will be deposited in Zoological Institute of the Russian Academy of Science, St Petersburg), Russia, Primorsky Region, Khasan District, Gamov Peninsula, Vityaz’, 42°35ʹ58.77ʺN / 131°11ʹ13.86ʺE, at light, 6.08.2018 (leg.

    1. Komarov).

      Distribution. Russia: Primorsky Region. South Korea (Mansu-san Mts.), China (Shaanxi), Taiwan.

      Note. This species was described from the western part of South Korea [Chûjô, Lee, 1993]. It was later recorded for the same area, Taiwan [Jung et al., 2009] and China (Shaanxi) [Wu, Ren, 2008]. Cryphaeus albopilosus is readily separable from other species of the genus by having the body covered by white recumbent hairs. The species is recorded from Russia for the first time.

      Bionomics. The specimen was collected in broad-leaved forest with Quercus sp., Acer sp., Juglans mandshurica, Phellodendron amurense. In Korea, the beetles were collected on Daedaleopsis sp. [Jung et al., 2009].
