Material examined. Three adult males extracted from the mature pupae, IRAN: Mazandaran Province, the right source of the Gelendrud River is slightly higher than the confluence with the left, altitude 1987 m above sea level, 36°18.276’N, 51°50.087’E. 26.VI.2019, leg. D. Palatov.

Remarks. The male of B. brevitarsis was described by Tokunaga (1936) from Japan and redescribed by Makarchenko (2008), with notice that this species is known only from Japan, all other records based on larvae from China and the Russian Far East should be revised.

B. brevitarsis is collected outside the Eastern Palearctic for the first time and therefore we found expedient to adduce here the short description of a male from the mountains of Iran.

In our opinion, the distribution of this species looks rather strange and in the future it is necessary to compare the data of DNA-barcoding of Japanese and Iranian populations to clarify their species unity or difference.
