Colletes cyanonitidus View in CoL sp. n.
Figs 5 View Fig , 30, 31 View Figs 28–39 , 40 View Fig
Etymology: Named for the characteristic bluish shine on the terga.
Diagnosis: Among the species with a reduced scopa C. cyanonitidus is unique in that it has an intense bluish shine on T1 and T2 (this is less intense in the very similar C. obscurus ) and the short plumose hairs on the scutellum and metanotum ( Fig. 5 View Fig ) (this is less developed in C. obscurus ). The male is best identified by the unique shape of the S7 ( Fig. 30 View Figs 28–39 ) and the narrow, very elongate, 2 nd hind tarsomere. This trait C. cyanonitidus shares only with a male of an undescribed species.
Description:
Female.
Length 10–11 mm.
Vestiture: Face short greyish white with long dark brown hairs on vertex; mesonotum with short yellowish brown hairs intermixed with numerous longer blackish hairs; mesosomal sides with longer and legs with white to yellowish white hairs that are shorter than face, scutellum and metanotum with short and medially plumose brownish orange hairs ( Fig. 5 View Fig ), scutellum intermixed with longer, blackish hairs; T1 very sparsely covered with moderately long, erect, white hairs, shorter posteriorly; disc of T2 sparsely covered with very short, depressed, whitish hairs; discs of T3–T5 with successively longer, erect, blackish hairs; moderately broad white posterior tergal hair bands on T1– T4, slightly narrowed medially on T1, very narrow on T5; T2 with weak and very narrow basal tomentum medially; S2–S4 with very short and indistinct white hair fringes laterally; discs of sterna very sparsely covered with very short hairs.
Integument: Mainly black, antenna brown ventrally, legs and tarsi partly with a reddish shine and terga posteriorly very narrowly translucent reddish brown; T1–T3 with bluish shine, more intense on T1; malar area narrow, length about 1/2 width of mandibular base; clypeus slightly depressed medially, with dense (0.2–0.5 pd), small punctures that are slightly elongate; integument between punctures glabrous; facial fovea narrow, maximum width about antennal diameter; disc of mesonotum with relatively dense (0.5–1 pd), fine punctation, surrounded by dense (<0.5 pd) punctation, integument between punctures glabrous; upper sloping part of propodeal triangle with short longitudinal carinae, vertical part distinctly shagreened and dull; disc of T1 with very fine, indistinct, sparse (1–2 pd) punctation, punctures becoming slightly finer and less distinct towards posterior tergal depression; punctation on disc of T2 similar but dense (0.5–1 pd); integument between punctures glabrous.
Male.
Length 9–10 mm.
Vestiture: Face white; mesonotum with long, yellowish white hairs; mesosomal sides and legs white to yellowish white, scutellum and metanotum with long yellowish to yellowish brown hairs, scutellum intermixed with few brown hairs; T1 densely covered with long, erect, greyish white hairs; disc of T2 with shorter hairs of same colour as T1; discs of T3–T6 with long, erect, blackish hairs; narrow and indistinct white posterior tergal hair bands on T1–T4, very narrow on T5; S1–S5 with short, dense fringes, laterally longer than medially; S6 laterally with a patch of short, very dense velvet-like hairs.
Integument: Completely black, except antenna dark brown ventrally, tarsi often brown and terga narrowly translucent posteriorly; T1–T5 with relatively intense bluish shine; malar area long, length about 3/4 width of mandibular base; clypeus with very dense (<0.2 pd) small punctures; facial fovea narrow, maximum width about 3/4 antennal diameter; disc of mesonotum with relatively small, scattered punctures (1 pd), integument glabrous, surrounded by dense (<0.2 pd) punctation; upper sloping part of propodeal triangle with short, longitudinal carinae, vertical part distinctly shagreened with some weakly developed more or less transverse carinae; hind femora ventrally swollen with a rounded edge medially that is covered with a brush of hairs; basitarsus of hind leg modified, slightly convex apically, with a prominent rounded tip dorsally that is apically beset with long, reddish bristles; basitarsus ventrally densely covered with long, reddish bristles; discs of T1 and T2 with relatively densely granular (0.5–1 pd) punctation, granulation becoming slightly finer and indistinct towards posterior tergal depression; integument between punctures glabrous.

Distribution: The species seems to have a strong preference for coastal sites of the southern Cape region ( Fig. 40 View Fig ).
Flower visiting: Carpobrotus edulis , C. sauerae (= C. quadrifidus ) ( Aizoaceae ).
