Remarks. T. setosus has been known from the male Holotype only (terra typica: Irkutsk). The species is closely related to T. basalis Erichson, 1839 and may be confused with the latter because of some variability. An additional material is necessary to delimit the two species more carefully. I report T. setosus here for Tuva Republic, Krasnoyarsk Territory, Buryatia Republic, the Russian Far East (Amur Area, Khabarovsk Territory, Sakhalin Area) for the first time. „ Tachinus sp.2 ” mentioned by Molodova (1973) from Sakhalin is in fact T. setosus .
