description: Colletes linzhiensis Niu, Zhu & Kuhlmann, sp. nov.
(Figs 2 a–e, 3a–f, 6)
Diagnosis: Within the C. foveolaris -group the female of C. linzhiensis sp. nov. is defined by a combination of the following characters: densely and finely punctate abdominal terga with narrow apical tergal hair bands (Figs. 2 d, 2e), short malar area, small apical grooves on the clypeus and abundant long black hairs along the inner eye margins, vertex (Fig. 2 b) and on the dorsal side of the thorax (Fig. 2 c). The male has a very large and broad S7 (Fig. 3 c) that is similar in shape to that of C. reinigi Noskiewicz and C. luzhouensis Kuhlmann. Colletes linzhiensis sp. nov. differs from C. reinigi by the finer and denser punctation of terga and the rounded outer apical corners of S7 (incised in C. reinigi). Colletes luzhouensis has a slightly longer and a bit more slender S7 and a longer gonostylus that at its base is narrower than in C. linzhiensis sp. nov. (Fig. 3 d).
Description: Female, BL=9.0–9.5mm (holotype: 9.5mm) (Fig. 2 a); head broader than long, HW:HL=60:50 (Fig. 2 b); gena nearly as broad as eye in lateral view, GW:EW=10:11 (Fig. 2 a); width of metasoma slightly narrower than that between tegulae, MtW:TW=70:72. Clypeus nearly as long as broad, with coarse and dense oblique spine-shaped punctation, apical grooves on clypeus small (Fig. 2 b); disc of scutum and scutellum shiny, with round and irregularly dispersed punctation (Fig. 2 c); malar area short, medially only half long as width of mandible base; facial fovea nearly as wide as width of antennal flagellum; propodeum laterally covered with sparse erect long paler hairs, integumental sculpture completely visible; punctation on disc of T1 fine, round and dense, i=0.5–1.0d; T1 with lateral white hair pathes and with basal white hair band, T2–T5 with narrow white apical hair bands (Figs. 2 d, 2e); sloping anterior and lateral anterior parts of T1 sparsely covered with erect long white plumose hairs. Antennal flagella ventrally black (Fig 2 b); all legs black. Along the inner eye margins, vertex (Fig. 2 b) and on the dorsal side of the thorax with abundant long black hairs (Fig. 2 c); Gena, pronotal lobe and mesepisternum covered with long paler yellowish-white plumose hairs.
Male, BL=8.0–8.5mm (Fig. 3 a); head broader than long, HW:HL=55:43; gena narrower than eye in lateral view, GW:EW=8:11 (Fig. 3 b); width of metasoma narrower than that between tegulae, MtW:TW=52:58. Antenna short, extending to scutellum, first flagellomere nearly as long as broad, 0.9 times as long as second flagellomere, second flagellomere longer than broad, nearly 1.2 times as long as broad, flagellomeres 3–11 roughly 1.3 times as long as broad and nearly equal to each other in length (Fig. 3 a); malar area medially about 2/3 long as width of mandible base; facial fovea shallow and narrow, only half as wide as antennal flagellum; propodeum laterally covered with sparse long erect hairs, integumental sculpture completely visible; disc of scutum and scutellum shiny, sloping anterior and lateral anterior parts of T1 covered with erect long white plumose hairs, disc of T1–T2 covered sparse long white plumose hairs (Figs. 3 e, 3f); disc of T1–T2 finely and densely pinctate, i=0.2–0.5d (Fig. 3 f); S7 large and broad, outer apical corner of S7 rounded (Fig. 3 c); gonostylus shorter than that of C. luzhouensis sp. nov., and broad at its base (Fig. 3 d). Antennal flagella ventrally black; all legs black. Face, vertex, scutum and scutellum covered with dense long paler white plumose hairs, intermixed with long black hairs (Fig.3 b); gena and mesepisternum covered with long white plumose hairs (Fig. 3 b).
