Аннотация:The male of Oreodytes okulovi LAFER 1988 is described for the first time. Until this study, this species was known only from the description of the female holotype and a few records without any descriptive notes, and thus the identity of the species remained unclear. The material studied includes males and females collected not far from the type locality in the Russian Far East; however, most interestingly, we have also studied two specimens from the Tuva Republic, Russia, more than 3,000 km west of the type locality. At first glance the species can be mistaken for O. sanmarkii (C.R. SAHLBERG 1826), but the shape of the aedeagus and some features of the ventral surface clearly separate O. okulovi from O. sanmarkii and other similar species. The habitus and the male genitalia are illustrated. An English translation of LAFER's original description – which is in Russian – is given in an Appendix.
