Diagnosis

Among all species of this group the female and male Colletes kogelbergensis are unique in having hairs on face and scutum (in female also scutellum) with partial brown tips. Additionally, the discs of T 1–2 in the female have reddish margins posteriorly ( Fig. 39D–E ). The male can be most easily identified by the unique shape of S7 ( Fig. 40G ) and gonostylus ( Fig. 40H ).

Etymology

Named after the Kogelberg Mountains where this species was discovered.

Description

Female

BODY LENGTH. 11 mm.

HEAD. Integument black, antenna brown ventrally. Face yellowish white ( Fig. 39B ), hairs partly with dark brown tips. Clypeus with fine, dense indistinct punctation (0.2 pd), punctures elongate, interspaces glabrous. Malar area narrow, length about ⅓ width of mandibular base. Facial fovea narrow, maximum width about 1–1.2 × antennal diameter.

MESOSOMA. Integument black except tarsi often brownish ( Fig. 39A ). Scutum with relatively long, yellowish white to yellowish brown hairs ( Fig. 39C ), with numerous hairs with dark brown tips. Mesosomal sides and legs grayish to yellowish white hairs, intermixed with some hairs with brown tips on mesepisternum. Disc of scutum with dense (0.5–1 pd) punctures, surrounded by dense punctation (0.5–1 pd). Integument shagreened and the punctures have a crater-like structure. Scutellum and metanotum with relatively long, yellowish brown hairs, on scutellum most hairs with dark brown tips. Upper sloping part of propodeal triangle scabricoulus, vertical part shagreened and shiny. Scopa dark brown dorsally, yellowish ventrally ( Fig. 39F ). Mid femora with a stout ridge ventrally and a brush of hairs.

METASOMA. Integument black. Terga translucent posteriorly, disc of terga 1 and 2 with reddish margins posterior ( Fig. 39D ). T1–T3 with slight bluish shine. T1 covered with long yellowish white erect hairs, medio-anteriorly with short concolorous hairs interspersed. Disc of T2 with some short erect yellowish white hairs. T2 with narrow basal tomentum. Discs of T3–T5 with successively longer, short erect blackish hairs. T1–T3 with relatively broad, yellowish white posterior tergal hair bands ( Fig. 39E ). Disc of T1 with fine and dense punctures (0.5–1 pd), punctures slightly smaller, finer and denser towards posterior tergal depression ( Fig. 39D ). Disc of T2 with very fine, indistinct and dense punctation (<0.5 pd); glabrous between punctures. S2–S5 with short yellowish hair fringes. Discs of sterna covered with short yellowish hairs, directed apically, longer on S2 medially.

Male

BODY LENGTH. 10–11 mm.

HEAD. Integument black, antenna ventrally dark brown. Face grayish to yellowish brown hairs ( Fig. 40B ), partly with darker brown tips. Clypeus with very dense, small punctures (<0.2 pd). Malar area narrow, length about ½ width of mandibular base. Facial fovea narrow, maximum width about antennal diameter.

MESOSOMA. Integument black, legs reddish brown, apical and basal end of tibiae and tarsi completely yellowish brown ( Fig. 40A ). Scutum with long, yellowish brown hairs, partly with brown tips. Mesosomal sides and legs yellowish to grayish white hairs, intermixed with some hairs with brown tips on mesepisternum. Disc of scutum with medium-sized dense punctures (0.5–1 pd), surrounded by dense punctation (<0.5 pd), integument shagreened and dull and the punctures have a crater-like structure ( Fig. 40C ). Scutellum and metanotum with long, yellowish white hairs, on scutellum with some darker hairs intermixed. Upper sloping part of propodeal triangle with short, longitudinal carinae anteriorly, scabriculous posteriorly. Vertical part superficially shagreened and shiny with 2 or 3, short, more or less transverse carinae. Hind basitarsus broadened apically ( Fig. 40F ). Dorso-apical edge is slightly beveled.

METASOMA. Integument black, terga narrowly translucent posteriorly. T1–T3 with slight bluish shine. T1 densely covered with long, erect yellowish white hairs ( Fig. 40D ). Disc of T2 with shorter, erect hairs. Discs of T3–T5 with relatively short, erect dark brown to black hairs. T1–T5 with narrow white tergal hair bands ( Fig. 40E ). Discs of T1 and T2 with fairly coarse distinct, dense punctation (<0.2 pd), punctures becoming slightly finer and shallower towards posterior tergal depression, interspaces glabrous ( Fig. 40D ). S1–S5 with short, yellowish white hair fringes, very short medially, longer laterally. Discs of sterna with short posterior directed hairs, laterally long yellow white hairs. S7 ( Fig. 40G ) and gonostylus ( Fig. 40H ) as illustrated.
