Colletes longimala Kuhlmann & Proshchalykin, sp. nov.

(Figs 3 a–f)

Diagnosis. Within the C. foveolaris -group the extremely elongate malar area of C. longimala (about twice as long as width of mandible base) is unique and slightly shorter in the closely related C. annapurnensis Kuhlmann, C. laevigena Noskiewicz and C. pseudolaevigena Kuhlmann. In C. annapurnensis and C. laevigena the shape of S7 closely resembles that of C. longimala but their gonostyli are about 1.5–2 times as long and distinctly curved upwards. In C. pseudolaevigena the gonostylus is slightly shorter than in C. longimala but its S7 is apically distinctly emarginate while it is truncate in C. longimala (Fig. 3 f).

Description. Female. Unknown.

Male. Bl: 9.0 mm. Head. Head much longer than wide (Fig. 3 c). Integument black except part of mandible dark reddish-brown. Face densely covered with long, greyish-white, erect hairs, vertex with very few dark brown hairs intermixed. Malar area medially about twice as long as width of mandible base, sparsely punctate, smooth and shiny between punctures (Fig. 3 d). Antenna black, ventrally dark brown. Mesosoma. Integument black. Disc of scutum smooth and shiny between punctures; disc very sparsely punctate (i = 3–5d) with small punctures.
