ABSTRACT. Data on morphological variability of Reptalus nigrovenosus (Kusn.) are presented, R. narynensis Emeljanov et Tishetshkin sp.n. closely related to the previous species is described. Both species produce calling signals with very similar temporal pattern and dwell on the same altitude in similar biotopes. On the other hand, they were never found in the same locality. Possibly, this is the similarity of signal structure that is the reason for their vicariation.
