Description

Gymnometriocnemus (Rhaphidocladius) kamimegavirgus Sasa et Hirabayashi, 1993

Figs 4, 5.

MATERIAL. Russia: Moscow Region, village Pervomayskoe, left bank of Zhiletovka river, pine forest with admixture of deciduous species 55.46164°N, 037.18284°E, 27.04– 7.05.2022, S.M. Tsurikov, A.G. Zuev (2 males, 7 females).

DIAGNOSIS. Males of this species seem to be much darker in comparison with specimens of G. (R.) brumalis: thorax and abdominal tergites dark brown, almost black. Wing membrane has setae on the most apex only. The species differs from G. (R.) tairaprimus by simple, not double, lower appendage of gonocoxite. The species differs from G. (R.) brumalis by strongly sclerotized and well visible lamella of virga and rounded, not angulate lower appendage of gonocoxite (Figs 4, 5) [Makarchenko, Makarchenko, 2019].

DISTRIBUTION. The species was described from the territory of Japan (Nagano, Honshu Island) [Sasa, Hirabayashi, 1993]. Registered in Norway [Stur, Ekrem, 2015]. In Russia it was found in the Far East (Magadan Region) only [Makarchenko, Makarchenko, 2019]. Our registration is the first for the European part of Russia.
