( Figs 3 a–d)

Diagnosis. Within the C. squamosus group C. uzbekus belongs to a group of large and robust (> 8 mm) species with dense and moderately coarse punctation on T1 ( Fig. 3 d) that include C. squamulosus Noskiewicz , C. bernadettae Kuhlmann and C. sellatus Morawitz. The latter has a uniquely modified mesoscutellum that is medioapically deeply depressed with lateral apically directed processes. In the similar sized C. squamosus Morawitz , C. wollmanni Noskiewicz , C. ottomanus Noskiewicz the punctation of T1 is much coarser with puncture diameters about double the size while it is very fine in all other species of this group. Colletes squamulosus differs from C. uzbekus most obviously by the very short scale-like hairs that form the apical tergal hair bands (long hairs in C. uzbekus , Fig. 3 d). In C. bernadettae these hairs are slightly shorter and broader than in C. uzbekus , the punctation of the terga and the disc of the clypeus is slightly coarser, and punctures are a bit more dispersed and more clearly defined.

Description. Female. Bl = 9.0–10.0 mm. Head wider than long. Integument black, mandible partly dark reddish-brown. Face, except clypeus, densely covered with long, yellowish-white, erect hairs, on vertex light brown ( Fig. 3 b). Clypeus convex, with shallow longitudinal median depression, supraclypeal area triangular and convex in profile. Clypeus basally finely and very densely punctate (i <0.5d), particularly in the median depression, subapically successively coarser punctate; surface between punctures smooth and shiny, small pair of apical clypeal depressions ( Fig. 3 b). Malar area medially very narrow, almost linear, finely striate. Antenna black, flagellum ventrally dark yellowish-brown ( Fig. 3 a). Mesosoma. Integument black. Mesoscutal disc densely and coarsely punctate (i = 0.5–1d), between punctures smooth and shiny ( Fig. 3 c). Mesoscutellum anteriomedially impunctate, smooth and shiny; apically densely and coarsely punctate ( Fig. 3 c). Mesoscutum, mesepisternum and propodeum densely covered with short light yellowish-white, erect, plumose hairs, a few light brown hairs intermixed ( Figs 3 a, c). Wings. Slightly yellowish; wing venation brown. Legs. Integument reddish-brown. Vestiture whitish to greyish-white, scopa white ( Fig. 3 a). Metasoma. Integument black to dark reddish-brown, depressed apical tergal margins reddish to yellowish translucent ( Fig. 3 d). T1 largely and densely covered with short appressed, yellowish-white hairs, leaving in unworn specimens (not imaged) only a narrow apical stripe glabrous; apical tergal hair band of T1 narrow, on following terga broad; T2 with broad basal hair band, glabrous disc about 1/2 to 2/3 as broad as the very broad apical tergal hair band; T3–T5 with broad apical tergal hair bands; terga apically distinctly depressed ( Fig. 3 d). Terga densely and relatively coarsely punctate (i = 0.5d), between punctures smooth and shiny ( Fig. 3 d). Apical sternal hair bands broad.

Male. Unknown.
