Colletes nigricans species-group

C. eous Morice : Figs 7 c, d

Colletes hylaeiformis species-group

C. hylaeiformis Eversmann : Figs 7 e, f

Colletes tardus species-group

C. tardus Noskiewicz : Fig. 10 e. S7 of this species is similar to C. inexpectatus and C. tuberculatus but in the former the hind basitarsus is apically slightly broadened ( Fig. 10 f, unmodified in C. tardus , see key). Compared to C. tuberculatus ( Fig. 10 b) the punctation of T 1-2 in C. tardus is finer, shallower and more dense. Colletes fodiens species-group

C. daviesanus Smith : Figs 9a , b

C. fodiens (Fourcroy) : Figs 9 c, d

C. similis Schenck : Figs 9 e, f

C. tuberculatus Morawitz : Figs 10a , b

Colletes anchusae species-group

C. anchusae Noskiewicz : Figs 11 e, f

Colletes marginatus species-group

C. chengtehensis Yasumatsu : Figs 13a , b. This species is very similar to C. marginatus but S7 is apically narrower, punctation on T1 is slightly finer and apical tergal hair bands are a bit broader than in C. marginatus . C. marginatus Smith : Figs 13 c, d. See C. chengtehensis .
