Colletes hirsutus, Niu, Ze-Qing, Zhu, Chao-Dong & Kuhlmann, Michael, 2013

Niu, Ze-Qing, Zhu, Chao-Dong & Kuhlmann, Michael, 2013, Bees of the Colletes clypearis - group (Hymenoptera: Apoidea: Colletidae) from China with descriptions of seven new species, Zootaxa 3745 (2), pp. 101-151 : 112

Colletes hirsutus sp. n.

( Figs 25 a–e, 32s)

Diagnosis. The female of this species is distinctive by a combination of the following characters: relatively dense and coarse punctation of T1–2, uninterrupted apical tergal hair band on T1, broad apical tergal hair bands on T2–5 and broad basal hair band on T2 ( Fig. 25 d, 25e). C. hirsutus sp. n. closely resembles a new species known from Kyrgyzstan and Tajikistan that is currently under description. From that species C. hirsutus sp. n. differs by the almost complete lack of black hairs on the scutum (abundant black hairs on the scutal disc in the other species), the slightly more dispersed punctation of the clypeus and the finer tergal punctation. The male is unknown.

Description. Female, BL= 8.5mm ( Fig. 25 a); head broader than long, HW: HL=58: 44 ( Fig. 25 b); gena obviously narrower than eye in lateral view, GW: EW=8: 13 ( Fig. 25 a); width of metasoma slightly narrower that between tegulae, MtW: TW=63: 65. Clypeus broader than long, with fine and dispersed round punctation ( Fig. 25 b); disc of scutum with regularly dispersed round punctation, i=0.5–1.5d ( Fig. 25 c); malar area medially shorter than width of mandible base, only 2/3 long as width of mandible base; facial fovea narrower than width of antennal flagellum; vertex behind eye rounded; propodeum laterally covered with sparse long erect hairs, integumental sculpture completely visible; punctation on disc of T1 fine, round and dense, irregularly dispersed, i=0.2–1.0d ( Fig. 25 e); T1–T4 with complete apical hair bands ( Fig. 25 d), T2 with broad basal hair band, nearly 1/2 width as the exposed T2 ( Fig. 25 e); sloping anterior and lateral anterior parts of T1 sparsely covered with erect long plumose hairs ( Figs. 25 d, 25e). Antennal flagellum ventrally blackish brown ( Figs. 25 a. 25b); tarsi of all legs brown, other parts blackish brown. Face, vertex covered with paler white erect long plumose hairs ( Fig. 25 b), scutum completely covered with yellowish white erect long plumose hairs, not intermixed with some black hairs ( Figs. 25 a. 25c), mesepisternum covered with longer white plumose hairs ( Fig. 25 a).

Male unknown.
