Colletes subnitens Noskiewicz 1936

( Figs 2 d, 4a–d, 14c–d)

Colletes subnitens Noskiewicz 1936: 345 –346 (lectotype—♂, designated by Kuhlmann 2000: 176, “Gunt River, protoka Chartyma, 2800 m [ Kazakhstan: South Altai mountains], 25.VI.1909, leg. A. Jakobson, Semenov-Tyan’-Shansky’s coll.” [ZISP]).

Material examined. Kalmykia Republic: 2 ♀, 1 ♂, 30 km NNW Sarny, Tsagan-Nur Lake [45.13E 47.22N], 19.V.1986, DRK ( ZISP / RCMK).

Distribution in Russia ( Fig. 2 d). * Kalmykia Republic.

General distribution. Kazakhstan, Iran, * Russia. First record of this species for Europe.

Remark. The record of C. subnitens from Krasnodar Prov. ( Warncke 1978: 348) is wrong and belongs to C. hakkari Kuhlmann 2002 .

The female of Colletes subnitens has been unknown and is here described for the first time.

Diagnosis. The female of C. subnitens can be distinguished from the other species of this group by a combination of the following characters: punctation on the disc of T1 relatively fine and dispersed ( Fig. 4 d) (finer in C. laevifrons Morawitz ; denser in C. hakkari Kuhlmann ; much coarser and denser in C. desertorum Kuhlmann , C. mlokossewiczi Radoszkowski ), punctation on the disc of T2 as on T1 ( Fig. 4 d) (much finer in C. desertorum , C. hakkari , C. hiekeseniori Kuhlmann , C. mlokossewiczi ; slightly finer in C. laevifrons ), apical clypeal grooves relatively small ( Fig. 4 b) (distinctly larger in C. hiekeseniori , C. laevifrons , C. mlokossewiczi , C. senilis (Eversmann)) .

Description. Female. Bl = 5.7–7.5 mm. Head. Head much wider than long ( Fig. 4 b). Integument black except part of mandible dark reddish-brown. Face except clypeus densely covered with long, greyish-white, erect hairs ( Fig. 4 b). Clypeus strongly convex, without longitudinal median depression, supraclypeal area rectangular and convex in profile, medially polished and shiny. Clypeus relatively finely and regularly densely punctate (i = 0.5d); surface between punctures smooth and shiny, small pair of apical clypeal grooves ( Fig. 4 b). Malar area medially about 1/4 as long as width of mandible base, finely sculptured. Antenna black, ventrally dark brown. Mesosoma. Integument black. Mesoscutal sparsely punctate (i = 2–3d), between punctures smooth and shiny. Scutellum anteriorly sparsely punctate, between punctures smooth and shiny, apically densely punctate ( Fig. 4 c). Mesoscutum, mesepisternum and propodeum densely covered with long greyish-white to greyish-brown, erect hairs ( Fig. 4 a, c). Wings. Very slightly brownish; wing venation dark brown. Legs. Integument black to dark reddish-brown. Vestiture whitish to yellowish-white, scopa greyish-white. Metasoma. Integument black except depressed apical tergal margins and and a narrow strip of the disc dark reddish translucent ( Fig. 4 d). T1 sparsely covered with a few long, erect greyish-white hairs; apical tergal hair bands laterally very broad, on T1 medially broadly interrupted, on T2 medially narrower than laterally, on following terga broad ( Fig. 4 d); terga apically very slightly depressed ( Fig. 4 d). T1 and T2 relatively sparsely and finely punctate (i = 1–2d), between punctures smooth and shiny ( Fig. 4 d); punctation on following terga much finer, denser and indistinct.
