Diagnosis
The female can be separated from that of all other species with a normal scopa by the combination of the following characters: apical hair band of T2 about ½ width of disc (Fig. 50D–E), malar area long
(¾ width of mandibular base), facial fovea elongate (about 1.5 x width of antennal flagellum), T2 with basal tomentum (Fig. 50D–E).
Etymology
Named after the Richtersveld National Park where this species was discovered.

HEAD. Integument black, antenna reddish brown ventrally. Face grayish to yellowish white, intermixed with brown hairs especially on vertex and along inner eye margins (Fig. 50B). Clypeus with fine and dense punctation (0.2 pd), punctures slightly elongate, interspaces glabrous. Malar area narrow, length about ¾ width of mandibular base. Facial fovea elongate, maximum width about 1.5 × antennal diameter.
MESOSOMA. Integument black, tarsi partly brownish (Fig. 50A). Scutum with relatively long, grayish to yellowish white hairs, intermixed with brown hairs (Fig. 50C). Mesosomal sides yellowish white, intermixed with brown hairs on mesepisternum, hairs on legs yellowish with brown hairs on tibiae and tarsi interspersed. Disc of scutum dense, fine (1–2 pd) punctured, integument glabrous, surrounded by dense (<0.5 pd) punctation, integument glabrous. Scutellum and metanotum with long, yellowish white hairs, intermixed with brown hairs. Upper sloping part of propodeal triangle scabriculous, vertical part with some transverse carinae anteriorly. Scopa dark brown dorsally, yellowish white ventrally (Fig. 50F). Mid femora with distinct edge, stout ridge ventrally and brush of hairs basally.

Disc of T2 densely covered with shorter, concolorous hairs. T2 with well developed, relatively broad basal tomentum. Discs of T3–T5 with successively longer, short erect blackish hairs.T1–T4 with relatively broad yellowish white posterior tergal hair bands (Fig. 50E). Disc of T1 with fine and dense punctation (0.5–1 pd), punctures much finer and denser on posterior tergal depression. Disc of T2 with fine and dense punctation (0.5 pd); glabrous between punctures.
