Abstract

The genus Asiacyon Mai, Jia, Ryndevich & Fikáček, 2024 from southern Xizang, China is studied. Four species are added to it, three of which are described as new: Asiacyon sherpaicus sp. nov., A. trilobatus sp. nov. and A. zhangmuensis sp. nov. Cercyon spatifer Hebauer, 2002 is transferred to Asiacyon. All species are diagnosed and illustrated in detail.
