Colletes harrerioides sp. n.

(Figs 21 a–e, 22a–e, 32q)

Diagnosis. This species is closely related to C. harreri and the female belongs to a small group of large species with finely and densely punctate terga but not as extreme as in C. babai, C. sodalis, C. heilongtanensis sp. n. and C. yanruae sp. n. A punctation similar to C. harrerioides sp. n. occurs in C. jankowskyi (Fig. 18 d) and C. harreri (Fig. 16 f). C. harrerioides sp. n. differs from C. jankowskyi in the slightly more sparse punctation on T1–2 (Fig. 22 e) and the much longer hairs on the scutum (about twice as long as in latter species). In C. harreri the punctures on T1 are slightly larger and more irregular (Fig. 16 f) than in C. harrerioides sp. n. and the clypeus is coarser and more sparsely punctate giving it a more shiny appearance (Fig. 16 e) than in C. harrerioides sp. n. The male S7 has a characteristic shape (Fig. 22 d) that is similar to that of C. harreri (Fig. 6 a) but is a bit broader medially. In C. harrerioides sp. n. the gonostylus (Fig. 22 b) is only about 2/3 as long as in C. harreri (Fig. 6 d). Differences in the tergal punctation are as described for the female.

Description. Male, BL=8.0–11.0 mm (Fig. 21 a); head obviously broader than long, HW: HL=60:46; gena slightly narrower than eye in lateral view, GW: EW =9: 11; width of metasoma slightly narrower than that between tegulae, MtW: TW=60: 63. Clypeus slightly convex, broader than long, with coarse and dense punctation and giving it a more shiny appearance; antenna short, extending to the apex of scutellum, first flagellomere nearly as long as broad, 0.7 time as long as second flagellomere, second flagellomere longer than broad, nearly 1.5 times as long as broad, flagellomeres 3–11 roughly 1.5 times as long as broad and nearly equal to each other in length; malar area medially nearly as long as width of mandible base; facial fovea narrow, only as wide as antennal flagellum; vertex behind eye rounded; propodeum laterally covered with sparse long erect hairs, integumental sculpture completely visible; disc of T1 with slightly sparse and coarse punctation, i=1.0–1.5d; posterior margin of T1 opaque dark brown; metasomal terga with white apical hair bands, the band on T1 interrupted medially, and that on T2–T4 uninterrupted and nearly 1/4–1/5 width as that of the related exposed terga, T2 without basal hair bands (Fig. 21 c, 21e); sloping anterior and lateral anterior parts of T1 covered with erect long numerous plumose hairs, and disc of T1–T2 also with erect long sparse plumose hairs (Fig. 21 e); apical lobe of S7 enlarged sheet-shaped, a bit broader medially, apical edge always reversely folded, subbasal part not swollen (Fig. 21 d); genitalia as showing in Fig. 21 b. Antennal flagellum ventrally blackish brown (Fig. 21 a) or black; all legs dark blackish brown or black. Face, vertex and scutum covered with dense long dark paler white plumose hairs, intermixed with some black hairs; gena and mesepisternum covered with long white plumose hairs.

Female, BL=9.0– 11 mm (Fig. 22 a); head broader than long, HW: HL=60: 50 (Fig. 22 b); gena slightly narrower than eye in lateral view, GW: EW=10: 12; width of metasoma slightly narrower that between tegulae, MtW: TW=67: 70. Clypeus broader than long, densely and coarsely punctate (Fig. 22 b); scutum with irregularly dispersed round punctation, i=0.5–2.5d (Fig. 22 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; posterior margin of T1 opaque dark brown; punctation on disc of T1 fine, round and irregularly dispersed, i=1.0– 1.5d (Fig. 22 e); apical hair band on T1 medially interrupted, T2–T5 with complete apical hair bands, the bands narrow, T2 without basal hair band, apical hair band on T2 nearly 1/4 width as the exposed T2; sloping anterior and lateral anterior parts of T1 sparsely covered with erect long plumose hairs (Fig. 22 d). Antennal flagellum ventrally blackish brown; all legs blackish brown. Face, vertex and scutum covered with dark yellowish brown erect long plumose hairs, intermixed with some blackish erect long plumose hairs (Fig. 22 a, 22b, 22c), especially the much longer hairs on scutum (Fig. 22 c); mesepisternum covered with longer white plumose hairs (Fig. 22 a).

Distribution. China (Sichuan, Xizang, Yunnan) (Fig. 32 q).

Floral records. Rubus sp. ( Rosaceae).

Etymology. The specific name is derived from harreri and Latin suffix – oides (similar), meaning the species is closely related to C. harreri Kuhlmann.
