( EV).   Remarks.I have described the continental species  T. exiguus, closely related to the insular  T. kabakovi Veselova, 1990, known from the holotype(male) and the single paratype(female). Schülke (l.c.) has seen the holotypeof  T. exiguus(male), the paratypeof  T. kabakoviand some specimens from the Chita Area and Zeya ( AmurArea). It was impossible to examine the single known male of  T. kabakovi(ZIN)to compare with the type male of  T. exiguus, because the former could not been found due to a great disorder in the collection of the Zoological Institute, St.- Petersburg. Schülke considered the paratypeof  T. kabakovito be conspecific to the  Tachinusfemales from Chita Area and put  T. exiguusin the synonymy of  T. kabakovi. This decision seems to have not sufficient justification, because females of closely related species in this group are often very difficult to distinguish. Unfortunately, no males of  T. kabakovifrom the type locality are available now.  I assume  T. exiguusto be widely distributed in E Siberiaand the Far East. It has been known from both Russia( AmurArea, Chita Area, BuryatiaRepublic) and NE Mongolia. Itis recorded here from TuvaRepublic for the first time. 1958-09-24 1979-08-30 1958-09-24 AREA, EV O. N.
