Colletes vestitus sp. n.
( Figs 3 View FIGURE 3 a–f, male; 4a–f, female; 6)
Diagnosis. In the female of this species the abdominal terga are completely and densely covered with appressed white hairs ( Figs 4 View FIGURE 4 e, 4f), a character that within the C. flavicornis -group is only shared by C. alicularis Noskiewicz and C. emaceatus Noskiewicz. From both species C. vestitus differs by its conspicuously raised clypeus ( Fig 4 View FIGURE 4 d) and the combination of black legs (at least partly yellowish-brown in C. emaceatus ) and a sparsely punctate clypeus ( Fig 4 View FIGURE 4 c) (densely punctate in C. alicularis ). In the male terga are also completely covered with appressed white pilosity ( Fig 3 View FIGURE 3 f) like in C. alicularis (male of C. pallipes Noskiewicz unknown). Both species are very similar but in C. vestitus S7 more distinctly emarginate ( Fig 3 View FIGURE 3 b) (almost linear in C. alicularis ) and the gonostylus is shorter but broader at its base ( Fig 3 View FIGURE 3 d).
Description. Male, BL=6.0– 6.5mm ( Fig 3 View FIGURE 3 a); head broader than long, HW:HL=42:36; gena clearly narrower than eye in lateral view, GW:EW=5:10; width of metasoma slightly narrower than that between tegulae, MtW:TW=34:40. Antenna short, extending to scutellum, first flagellomere nearly as long as broad, 0.7 time as long as second flagellomere, second flagellomere longer than broad, nearly 1.3 times as long as broad, flagellomeres 3– 11 roughly 1.4 times as long as broad and nearly equal to each other in length ( Fig 3 View FIGURE 3 e); malar area medially about 2.0 times long as width of mandible base; facial fovea shallow and narrow, only 0.5 times as wide as antennal FIGURE 6.

flagellum; propodeum laterally covered with sparse long erect hairs, integumental sculpture completely visible; disc of scutum shallowly and sparsely punctate, i=2.0–3.5d, and disc of scutellum smooth and shiny, without punctation; posterior margin of T1 yellowish brown ( Fig 3 View FIGURE 3 f); disc of T1 dispersed and finely punctate, i=1.0–2.0d; metasomal terga densely covered with long appressed white plumose pilosity ( Figs 3 View FIGURE 3 a, 3f); sloping anterior and lateral anterior parts of T1 covered with long white erect plumose hairs ( Fig 3 View FIGURE 3 f); apical lobe of S7 medially emarginate and enlarged apically ( Fig 3 View FIGURE 3 b); genitalia as showing in Fig 3 View FIGURE 3 c (in dorsal view) and Fig 3 View FIGURE 3 d (in lateral view). Antennal flagella ventrally yellowish brown ( Fig 3 View FIGURE 3 e); tarsi of all legs yellowish brown, other parts black. Face covered with dense long white plumose hairs; gena, vertex, scutum, scutellum and mesepisternum covered with long white plumose hairs.
Female, BL=6.0mm ( Fig 4 View FIGURE 4 a); head broader than long, HW:HL=47:38 ( Fig 4 View FIGURE 4 c); gena clearly narrower than eye in lateral view, GW:EW=5:12 ( Fig 4 View FIGURE 4 d); width of metasoma narrower that between tegulae, MtW:TW=38:48. Clypeus nearly as long as broad, obviously raised ( Fig 4 View FIGURE 4 d), finely and sparsely punctate ( Fig 4 View FIGURE 4 c); disc of scutum smooth and shiny, marginal area of scutum finely and sparsely punctate, and scutellum smooth and shiny, without punctation ( Fig 4 View FIGURE 4 b); malar area medially nearly as long as width of mandible base ( Fig 4 View FIGURE 4 d); facial fovea narrower than width of antennal flagellum, only 0.5 times as wide as antennal flagellum; propodeum laterally covered with sparse long erect hairs, integumental sculpture completely visible; posterior margin of T1 yellowish brown ( Fig 4 View FIGURE 4 f); disc of T1 densely and finely punctate, i=0.5–1.0d ( Fig 4 View FIGURE 4 f); sloping anterior and basal parts of T1 covered with long white appressed plumose hairs, lateral anterior part of T1 covered with erect long white plumose hairs ( Fig 4 View FIGURE 4 e, 4f); metasomal terga completely and densely covered with appressed white plumose hairs ( Fig 4 View FIGURE 4 e). Antennal flagella ventrally yellowish brown ( Fig 4 View FIGURE 4 b, 4c); mediotarsi and distitarsi of forelegs, mediotarsi and distitarsi of middle legs, and hind tarsi dark brown, other parts black. Face, vertex, scutum and mesepisternum covered with long white plumose hairs ( Fig 4 View FIGURE 4 c, 4d); scutum and scutellum covered with long paler white plumose hairs ( Fig 4 View FIGURE 4 b).
Type material. Holotype: 1♀, China, Xinjiang, Fukang, Cainan (87º54′E, 44º06′N), 27.V.2013, coll. Liu- Sheng Cheng; Paratypes: 1♀, 9♂, same label information as holotype.
Distribution. China: Xinjiang (Fukang, Cainan) (Fig 6).
Floral association. No record.
Etymology. The specific epithet is Latin vestitus , meaning the metasomal terga densely covered with plumose hairs.
DNA Barcoding. We sequenced 10 specimens of this species, with 8 males and two females. All sequences were grouped in the same highly supported branch to confirm the species identity of both sexes ( Fig 5 View FIGURE 5 ).
