Diagnosis. The combination of malar area 0.5× as long as basal width of mandible, mesoscutum with mostly paleorange hairs and tegula dark-brown to black can be used to differentiate females of C. collaris from those of the other Tibetan species of Colletes , except C. bischoffi , but the former are distinct in having the malar area 0.5× as long as basal width of mandible (malar area 0.75× as long as basal width of mandible in C. bischoffi ) and the supraclypeal C. bischoffi , but the former are different by having the combination of hind basitarsus 5.25× as long as broad (hind basitarsus 4.5× as long as broad in males of C. bischoffi ) and S7 with apicolateral lobes narrower than gonobase (S7 lobes broader than gonobase in males of C. bhutanicus ).

Remarks. In their synopsis of the C. succinctus group of China, Niu et al. (2013a) noted that populations of C. collaris of Spain and northeastern China are virtually indistinguishable from each other morphologically, although the authors found significant morphological differences (including the shape of the male S7) in specimens from Sichuan and Yunnan. This led them to suggest that the populations from southern China could be from a separate cryptic species, but in the absence of supporting DNA barcodes, a single species was recognized nonetheless. Unfortunately, there were no additional DNA-grade specimens of C. collaris from either Sichuan or Yunnan available for us to sequence, even though newly-barcoded specimens from Beijing and southeastern Xizang (~2,300 the one found in the western Palaearctics (where the type localities are located), it is safe to conclude that the species illustrated and keyed out in this paper corresponds to the actual C. collaris , regardless of whether multiple cryptic species will be recognized in the future.
