Colletes pesenkoi Kuhlmann & Proshchalykin sp. nov.

( Figs 7 a–d)

Diagnosis. Colletes pesenkoi belongs to the C. marginatus -group that in the males is characterized by the shape of S7. This species is unique in this species-group because the punctation of the metasomal terga is sparse (i = 1–2 d) ( Fig. 7 b) while in all the other species of the group terga are densely punctate (i <d).

Description. Female. Unknown.

Male. Bl = 7.0 mm. Head. Head wider than long. Integument black except tips of mandible partly dark reddishbrown. Face densely covered with long, yellowish-brown, erect hairs. Malar area medially about 1/3 as long as width of mandible base, finely striate. Antenna black, ventrally dark brown. Mesosoma. Integument black. Mesoscutal disc between punctures smooth and shiny; disc densely punctate (i = 1.0–1.5d). Scutellum anteriorly with few punctures but with more dense punctation apically, surface smooth and shiny. Mesoscutum, scutellum, metanotum, mesepisternum and propodeum covered with long, yellowish-brown erect hairs ( Fig. 7 a). Wings. Slightly yellowish-brown; wing venation brown. Legs. Integument black to dark reddish-brown. Vestiture yellowish-white. Metasoma. Integument black except depressed apical tergal margins reddish to yellowish translucent ( Fig. 7 b). T1 and disc of T2 sparsely covered with long, erect yellowish-white hairs ( Fig. 7 b); apical tergal hair bands broad ( Fig. 7 a, b).
