REMARKS. This South Urals Autosilis species seems to be rare, as even the intensive collecting in its exclusive biotopes was yielding just one specimen a year, one in 1984, another in 1985 and the third in 1986. There are actually two Autosilis species distributed in relatively close proximity to A. olschwangi : the European A. nitidula (Fabricius, 1792) , registered in Ryazan and Yaroslavl Oblasts west of Iremel, as well as in Tomsk Oblast east of it, and A. dzungarica (Kazantsev, 1994) known only from the Saur and Tarbagatai mountain ranges in Kazakhstan. The shortest distance between the distribution areas of A. olschwangi and A. nitidula is thus roughly 1,000 km in the west and 1,600 km in the east, while that between A. olschwangi and A. dzungarica is about 2,000 km. The remaining six Autosilis species of the Russian Federation and adjacent territories are come across much farther away in the east: in East Siberia [ A. bianchii (Barovskij, 1926) ; A. jacutica (Barovskij, 1926) ; A. tuvensis ( Kazantsev, 2008) ; A. urjanhaica ( Kazantsev, 1997) ] and the Far East [ A. amurensis ( Kazantsev, 2008) and A. triimpressa (Pic, 1926) ] [Kazantsev, 1994, 1997, 2008, 2011].

The division of the genus into species groups, however, is yet to be carried out: it is therefore difficult to say what the closest relatives of A. olschwangi are.
