Colletes laticaudus: Cockerell 1945 (1946) : 850–851. Type locality: South Africa, Matjesfontein .
Diagnosis:Among the species with a reduced scopa is the following unique combination of characters: hind legs black to dark brown, hind tibia with dense short hairs dorsally ( Fig. 3 View Figs 1–4 ), apical tergal depressions broadly translucent. Male best identified by the unique shape of S7 ( Fig. 24 View Figs 18–27 ).
Description:
Female.
Length 11–12 mm.
Vestiture: Face yellowish,white with longer, dark brown hairs on vertex; mesonotum with short, yellowish brown hairs intermixed with numerous longer blackish hairs; hairs on side of mesosoma longer, and those on legs shorter and yellowish white, scutellum and metanotum with short, orange-brown hair, metanotum with a tuft of coloured plumose hairs medially; T1 sparsely covered with moderately long, erect, yellowish brown hairs; disc of T2 with very short, erect, yellowish hairs; discs of T3– T5 with successively longer, erect, blackish hairs; T1–T4 with relatively broad, white posterior fringes, that on T1 narrow medially, and on T5 entirely very narrow; T2 with narrow basal tomentum; S2–S4 with very sparse, short, white, fringes laterally; discs of sterna loosely clothed with very short hairs.
Integument: Mainly black, antenna brown ventrally, legs partly reddish brown and terga translucent yellowish or reddish brown posteriorly; discs of T1–T4 with narrow, red posterior margins; malar area narrow, length about 1/2 to 3/4 width of mandibular base; clypeus slight depressed medially, with dense (0.2 pd) small punctures that are very slightly elongate; integument between punctures glabrous; facial fovea broad, maximum width about 2× antennal diameter; disc of mesonotum glabrous, surrounded by dense (0.5 pd) punctation, integument between punctures glabrous; upper sloping part of propodeal triangle with short, longitudinal carinae, vertical part superficially shagreened and shiny; disc of T1 with distinct, fine, dense (0.5 pd) punctation, punctures becoming slightly finer and indistinctly shallow towards posterior tergal depression; disc of T2 with fine, dense (<0.5 pd) punctation; integument between punctures smooth and shiny.
Male.
Length 10–12 mm.
Vestiture: Face white; mesonotum with long, white to greyish white hairs; mesosomal sides and legs white to greyish white, scutellum and metanotum with long yellowish to yellowish white hairs, scutellum with a few brown hairs intermixed; T1 very densely covered with long, erect, yellowish brown hairs; disc of T2–T3 with successively shorter, concolorous hairs; T4–T5 with long, erect, black hairs; relatively broad white posterior fringes on T1–T4, that on T1 indistinct; S2–S5 with dense but short fringes, laterally longer than medially, discs of S2–S3 with velvutine pilosity posteriorly, widest medially. Integument: Completely black, except antenna brown ventrally, legs reddish brown, tarsi reddish brown to yellowish brown and terga narrowly translucent posteriorly; discs of T1–T3 with very narrow, red posterior margin; T1–T2 partly with very slight bluish shine; malar area long, length subequal to width of mandibular base; clypeus with very dense, small punctures (<0.2 pd); facial fovea broad, maximum width about 1.5× antennal diameter; disc of mesonotum with fairly coarse, scattered punctures (1–1.5 pd), integument glabrous, surrounded by slightly denser (0.5 pd) punctation; upper sloping part of propodeal triangle scabiculous, vertical part superficially chagreened and shiny, anterior margin with 2 or 3 short, weakly developed more or less transverse carinae; hind basitarsus slightly broadened apically with prominent, long, reddish bristles on dorsoapical edge; discs of T1 and T2 with fine and dense (0.5 pd) granulation, granulation fades towards posterior tergal depression, which is nearly smooth and shiny; integument between granulation smooth and shiny. Shape of S7 as in Fig. 24 View Figs 18–27 and shape of gonostylus as illustrated ( Fig. 25 View Figs 18–27 ).
