Colletes xizangensis ; Ascher & Pickering 2021.

Diagnosis. The female of C. xizangensis (the male is still unknown) is unique among the Tibetan Colletes in having the face and mesosoma covered entirely with pale-yellow pubescence and the T1 with a complete apical band. Females of C. xizangensis closely resembles those of C. xuezhongi , but in the former the clypeal punctation is crowded (clypeus more sparsely (i=1.0–2.0 d) punctate in C. xuezhongi ) and the T2 basal band is absent (T2 basal band present in C. xuezhongi ). Females of C. xizangensis are also similar to those of C. inspersus , but the former are comparatively larger (HW 3.2–3.3 mm) then the former (HW 2.8–2.9 mm) and have the paraocular area without black hairs (paraocular area with pale-yellow and black hairs intermixed in C. inspersus ).
