Mongolojassus vinokurovi Emelyanov, 1976 Figs. 24–31 Material examined. Russia, Eastern Siberia, Irkutsk Oblast, Balagansk Region, env. Khairyuzovka Village on the bank of Angara River, A. Zakhvatkin, 15–26. VI. 1932, 6 ♂, 3 ♀. Description. Similar in appearance to other members of the genus Mongolojassus. Aedeagal processes in posterior view at bases smoothly bent basad and diverging at angle slightly less than 90 o, without additional branches or denticles, straight or with tips only slightly bent outwards (Figs. 24–25). Length of processes averages 1/5–1/6 of shaft length. Aedeagal shaft S-curved in lateral view, with processes either parallel to or slightly bent towards shaft (Figs. 26–27). Gonopore somewhat distant from aedeagal apex, postgonoporal part of shaft distinctly narrowed (Fig. 28). Investigated specimens from Irkutsk Oblast are indistinguishable from type specimens from Yakutia in aedeagus shape (Figs. 24–28 and 29–31) in spite of the fact that the distance between these localities exceeds 1800 km. Distribution. Until now M. vinokurovi was considered endemic to Yakutia (Sivtsev & Vinokurov, 2002). The finding of this species in the steppe enclave in the Lower Angara River Valley significantly expands its known distribution. Further records of this species in local steppe areas in river valleys of Eastern Siberia can be expected.
