by face and mesosomal dorsum without black hairs and T2–T3 apical bands narrower than MOD in lateral view. Colletes packeri is most similar to C. floralis , however, the females of the former are distinct in having the malar area 0.4× as long as basal width of mandible (malar area 0.6× as long as basal width of mandible in the latter) and the hind basitarsus with dark setae (hind basitarsus with pale setae in the latter). Males of the two species can be differentiated by the malar area 0.75× as long as basal width of mandible in C. packeri (malar area 1.25× as long as basal width of mandible in C. floralis ) and the gonostylus concave dorsally in C. packeri (gonostylus nearly straight dorsally in C. floralis ).

Distribution. Ranging from western China (Xizang) south to Trang ( Thailand) and southeast to Vientiane ( Laos).

DNA barcode. Available (3 ♂). See also Fig. 1 and Table 1.

Floral hosts. Unknown.

Remarks. Contrary to what Kuhlmann & Proshchalykin (2015) asserted, none of the males from Yunnan ( China) previously identified as C. sodalis by Niu et al. (2013b) revealed to be C. packeri . Nonetheless, C. packeri is herein confirmedly recorded in China for the first time.
