Colletes luzhouensis Kuhlmann, 2007 467 (holotype ♂: China, Sichuan [USNM]).

Colletes luzhouensis ; Niu et al. 2014b: 465 ; Ascher & Pickering 2021.

Diagnosis. The following set of features may be used to differentiate females of C. luzhouensis from those of the other Tibetan Colletes , except C. linzhiensis (females of the two species are indistinguishable morphologically): mesoscutum with mostly black hairs, hind basitarsus with dark setae and T2–T3 apical bands narrower than MOD in lateral view. Males of C. luzhouensis are diagnosable by the combination of malar area as long as basal width of mandible, paraocular area with a well-defined longitudinal band of black hairs, T1 densely punctate (i<0.5 d) medially and gonostylus apex narrowly rounded. In males of C. linzhiensis , the gonostylus apex is distinctly pointed.

New records —none.

Distribution. China, ranging from Beijing west to Xizang and south to Yunnan.

DNA barcode. Unavailable.

Floral hosts. Leguminosae: Caragana sp. ; Rosaceae : Potentilla chinensis Ser. , Rubus sp.

Remarks. As pointed out above, the female of C. luzhouensis is, as far as we can determine, morphologically indistinguishable from that of C. linzhiensis . Therefore, both are keyed out indistinctly in the same couplet in the key given below.
