Viperidae

Gloydius Hoge et Romano-Hoge, 1981

Gloydius is represented in Mongolia by two species: G. ussuriensis , which was recently recorded for the east of the country ( KROPACHEV et al. 2016) and G. halys (Pallas, 1776) , formed by the nominal subspecies G. halys halys , widely distributed over the country, and G. halys stejnegeri (Rendahl, 1933) restricted to the south-eastern region ( ORLOV & BARABANOV 1999, WAGNER et al. 2016).

Most of the collected specimens of Kaszab’s expeditions correspond to G. halys halys , except the specimen ID178, which is located close to the distribution area of G. halys stejnegeri (see distribution map in ORLOV & BARABANOV, 1999), consequently, we herein tentatively assign this specimen to G. halys cf. stejnegeri (see Fig. 9 and Appendix).
