Colletes aureocinctus: Cockerell 1945 (1946) : 840. Type locality: South Africa, Matjesfontein .
Diagnosis: The very broad and conspicuous orange posterior tergal hair bands on the female are similar to C. fasciatus and C. latefasciatus , but it differs in having broadly translucent apical tergal depressions on T1–T3 and narrow red margins on posterior part of discs. The male is best identified by the unique shape of S7 ( Fig. 20 View Figs 18–27 ).
Description:
Female.
Length 13–14 mm.
Vestiture: Face white to greyish white with blackish hairs intermixed on inner eye margins and vertex; mesonotum with short, yellowish white hairs intermixed with numerous longer, blackish hairs; mesosomal sides and legs yellowish to greyish white, scutellum and metanotum with long, yellowish brown hairs intermixed with longer blackish hairs; scopa dark brown dorsally and yellowish white ventrally; T1 loosely covered with short, erect, yellowish white hairs; disc of T2 with few very short, whitish hairs; discs of T3– T5 with successively longer, erect, blackish hairs; T1–T4 with very broad, orange, posterior tergal hair bands comprising very fine, dense pilosity, narrower on T5; T2 with well developed yellowish basal tomentum; S2–S5 laterally with short, loose, white hair fringes.
Integument: Completely black, except antenna brown ventrally, tarsi often brownish and terga broadly translucent posteriorly and narrow red margins on posterior parts of discs of T1–T3, less developed on T4; T1 with slight bluish shine; malar area elongate, length about 3/4 width of mandibular base; clypeus with dense (0.2 pd) medium-sized punctures that are strongly elongate forming long, more or less U-shaped carinae on lower part of the clypeus; integument between punctures very slightly shagreened and shiny; facial fovea narrow, maximum width about 2/3 antennal diameter; disc of mesonotum without punctation or with very few, coarse punctures, integument glabrous, surrounded by dense (<0.5 pd) punctation; upper sloping part of propodeal triangle with short longitudinal carinae, vertical part superficially shagreened and slightly dull; disc of T1 with shallow, fine, relatively dense (1–2 pd) punctation, punctures becoming much finer (but a bit more distinct) and denser on posterior tergal depression; disc of T2 with very fine, dense (<0.5 pd) punctation; integument between punctures glabrous.
Male.
Length 10–13 mm.
Vestiture: Face greyish white to white; mesonotum with long, greyish white to white hairs; mesosomal sides and legs white, scutellum and metanotum with long yellowish white hairs; T1 densely covered with long, erect, greyish white hairs; disc of T2 and T3 with successively hairs shorter but same colour as T1; discs of T4 with white and black and T5–T6 with long, erect, blackish hairs; narrow white posterior tergal hair bands on T1–T5; S1–S5 with dense, long fringes, laterally longer than medially.
Integument: Completely black except tarsi often reddish brown, terga posteriorly narrowly translucent; T1–T3 with very slight bluish shine; malar area long, about as long as width of mandibular base; clypeus with very dense, small punctures (<0.2 pd); facial fovea narrow, maximum width about 1/2 antennal diameter; disc of mesonotum with medium-sized, scattered punctures (1–2 pd), glabrous, surrounded by dense (<0.2 pd) punctation; upper sloping part of propodeal triangle with short, longitudinal carinae anteriorly, vertical part glabrous; hind basitarsus modified, sightly curved and weakly broadened apically, with prominent long reddish bristles on dorsal apical edge; discs of T1 and T2 with distinct fairly coarse, dense (<0.5 pd) punctation, punctures becoming slightly finer and indistinctly shallow towards posterior tergal depression; integument between punctures glabrous.
