Abstract
A new species, Crossocerus (Crossocerus) rasnitsyni sp.n. is described from Southeast Kazakhstan (the Sholak Ridge).This species is the most closely related to C. (C.) wesmaeli (Vander Linden), but differs in having less developed yellow pattern of the body, shape of the clypeus, form and sculpture of the parietal area, shorter metasomal tergum I, and sculpture of the propodeal enclosure.The new species also differs from other similar species of Crossocerus s.str.by the absence of basal constriction on metasomal tergum II, structure of pronotum, unmodified male antenna and legs, particular structure and sculpture of the propodeal enclosure, absence of pubescence on the ventral surface of mesothorax, and details of body, antennal and leg coloration.ÐÅÇÞÌÅ.Îïèñûâàåòñÿ íîâûé âèä Crossocerus (Crossocerus) rasnitsyni sp.n.èç Þãî-Âîñòî÷íîãî Êàçàõñòàíà (õðåáåò Øîëàê).Ýòîò âèä íàèáîëåå áëèçîê ê C.
