Description Female BODY LENGTH. 4.5–5.2 mm . HEAD. Head slightly wider than long. Integument black, except part of mandibles dark reddish-brown. Face sparsely covered with long, greyish, erect hair ( Fig. 11C ). Clypeus slightly convex with sparse fine and shallow punctation (i = 2–3 d); surface between punctures apically superficial and shiny, basally distinctly reticulate and matt ( Fig. 11 C–D). Malar area medially narrow, almost linear. Antenna dorsally light brown, ventrally yellowish-brown ( Fig. 11C ). MESOSOMA. Integument black. Mesoscutal disc between punctures densely reticulate, matt; disc sparsely (i = 3–5 d) and shallowly punctate ( Fig. 11 E–F). Metanotum slightly shorter than basal area of propodeum, apically with narrow carinate depression ( Fig. 11F ). Propodeum broadly but finely carinate ( Fig. 11F ). Mesoscutum, scutellum, metanotum, mesepisternum and propodeum sparsely covered with short, greyish, erect hair ( Fig. 11A ). WINGS.

Integument black, except mandible partly dark reddish-brown. Face densely covered with long, greyish-white, erect hair. Malar area medially narrow, almost linear. Antennal flagellum bright yellowish-orange, medioapically broadened ( Fig. 12B ). MESOSOMA. Integument black. Mesoscutal disc impunctate, strongly and densely sculptured, completely matt. Mesoscutum, scutellum, metanotum, mesepisternum and propodeum covered with long, greyish, erect hair ( Fig. 12A ). WINGS. Slightly yellowish-brown; wing venation yellowish-brown, stigma bright yellow ( Fig. 12A ). LEGS. Integument black, tarsi, tibiae and femora apically yellow, tibia on both sides with darker spots of variable size ( Fig. 12A, E ). Hind tibia basally slightly curved, apically broadened and with a dense tuft of short, white hair on the inside ( Fig. 12E ). Vestiture greyish-white. METASOMA. Integument black, apical margins of terga narrowly translucent yellowish-brown ( Fig. 12C ). T1 medially, T2 densely and following terga successively less covered with short, appressed scale-like hair; apical tergal hair bands missing on all terga ( Fig. 12C ). Terga impunctate, densely sculptured and matt; terga with narrow apical tergal depression ( Fig. 12C ). S3–S5 without conspicuous apical hair fringes. TERMINALIA. S7 ( Fig. 12D ) and terminal plate of S8 ( Fig. 12F ) as illustrated. Distribution The species is only known from the type locality in the Knersvlakte, a semi-desert plane in southern Namaqualand.
