COMPARATIVE DIAGNOSIS. A new species is similar to K. sentum van Achterberg et Gómez, 2011 from Spain by having the process on the fifth metasomal sternite of female, but differs from it the shape of metasomal process (it is apically wide and obtuse, but narrow and acuminate in K. sentum ), scape longer than pedicel

Hind tibia distinctly widened towards apex, 1.1–1.2 times longer than femur, 0.7 times as long as hind tarsus. Spurs of hind tibia acute apically, inner spur 0.7 times as long as hind basitarsus. Hind tarsus thickened basally and evenly narrowed towards apex. All tarsal claws slender and simple.

Metasoma 1.1–1.3 times longer than mesosoma. First tergite strongly and roundly widened towards apex, weakly convex laterally, with spiracular tubercles. Apical width of first tergite 2.3–2.8 times its minimum basal width, length 0.65–0.75 times its apical width. Suture between second and third tergites distinct. Second tergite

ETYMOLOGY. From “austrus” (Latin for “south”), and "rossicus" (Rossia),

because species was collected in the south of the European part of Russia.

REMARKS. The two other known female of this new species are without distanced obtuse process on fifth sternite, because it is perhaps mobile and can situated to press to the middle lower margin of sternite!
