Crossocerus yasumatsui mongolensis Tsuneki, 1972: 151 , ♀ (holotype: ♀, Mongolia, Hovd Aimag, “Mongol-Altaj-Gebirge, 44 km N von Somon Uenč im Tal, Uenč gol, 1780 m, 8.VII.1966, Z. Kaszab ”, [Természettudományi Múzeum, Budapest, Hungary]).

MATERIAL. RUSSIA: 1♂, Tyva Rep., 25 km SE Ersin, Tes-Khem , 50.0798°N 95.352983°E 14.VII.2014 (A. Lelej, MP, VL) [MMC]; 5♂♂, 1♀, Altai Rep., 15 km SE Kuray, 50.1861°N 88.1178°E, 17, 19, 22.VI.2022 ( MP, AF) [MMC/ FSCV] .

DISTRIBUTION. Russia (Altai, * Tyva Rep., Irkutsk Prov., Buryat Rep., Zabaikalskii Terr., Yakut Rep., Magadan Prov., Chukot Autonomous Area , Khabarovsk Terr., Amur Prov., Primorskii Terr.) , Kazakhstan, Kyrgyzstan, Mongolia.

DISCUSSION. K. Tsuneki [1972] described Crossocerus yasumatsui mongolensis very briefly, indicating as a difference only the smoother sculpture of the metapostnotum and propodeum of female. Based on a comparison of females, P. Nemkov [2004: 254] synonymized Crossocerus yasumatsui mongolensis Tsuneki, 1972 with C. yasumatsui ( Tsuneki, 1947) described from Hokkaido, Japan ( Tsuneki, 1947). However, a careful comparison of materials from the mainland and the Kunashir Island revealed a number of differences that allow us to judge the species status Crossocerus mongolensis Tsuneki, 1972 , stat.n. The differences between Crossocerus mongolensis and C. yasumatsui are outlined in Table 1 and Figs 5–18 .
