Diagnosis

Females of R. karooensis   sp. nov. can be separated from other Redivivoides   species by a combination of the following characters: metasomal terga black to brown, T2 densely punctate with large punctures and surface between punctures smooth and shiny, white apical tergal hair bands present ( Fig. 7D View Fig ), prepygidial and pygidial fimbria dark brown to black ( Fig. 7D View Fig ). These characters also apply to males ( Fig. 8C View Fig ) but the genitalia and S6 – S8 ( Fig. 8 View Fig D-H) should be checked to avoid potential confusion with the unknown male of R. eardleyi   .

Etymology

Named after the Karoo, the arid region in western and central South Africa where this species was found.

Description

Female

BODY LENGTH. 9.5-10.5 mm

HEAD. Head slightly wider than long. Integument black except mandibles and labrum largely dark reddish-brown. Face sparsely covered with long, yellowish-grey, erect hairs intermixed with black hairs especially along the inner eye margins and on vertex ( Fig. 7B View Fig ). Clypeus slightly convex, apically narrowly impunctate; medially densely covered with medium-sized punctures that become gradually smaller and denser towards the lateral and upper margins; surface between punctures shiny or superficially shagreened ( Fig. 7B View Fig ). Malar area medially narrow, almost linear. Antenna black, ventrally orange to reddish-brown.

MESOSOMA. Integument black. Mesoscutal disc between punctures smooth and shiny; disc densely (i = 0.5–1.0 d) and finely punctate ( Fig. 7C View Fig ). Mesoscutum, scutellum, metanotum, mesepisternum and propodeum covered with long yellowish-brown erect hairs, black hairs intermixed on mesoscutum ( Fig. 7C View Fig ).

WINGS. Yellowish-brown; wing venation brown.

LEGS. Integument black to dark reddish-brown. Vestiture of femora whitish-yellow, on tibiae and tarsi dark brown to black, scopae very sparse, dark brown to whitish-grey.

METASOMA. Integument black, apical margins of terga narrowly translucent reddish-brown ( Fig. 7D View Fig ). T1 apically and T2 on disc sparsely covered with long erect yellowish-white hairs; T3 – T4 covered with short yellow to black hairs; apical tergal hair band missing on T1, on T2 – T4 broadly white ( Fig. 7A, D View Fig ). Prepygidial and pygidial fimbriae black. T1 almost impunctate, polished and shiny, T2 – T4 shiny, with very fine, superficial and sparse punctation that becomes progressively denser on apical terga ( Fig. 7D View Fig ).

Face densely covered with long, yellowish-brown, erect hairs intermixed with black hairs along the inner eye margins and on vertex. Malar area medially narrow, almost linear. Antenna black, ventrally yellowish to reddish-brown.

MESOSOMA. Integument black. Mesoscutal disc between punctures smooth and shiny or superficially shagreened; disc densely (i = 0.5-1.0 d) and finely punctate ( Fig. 8B View Fig ). Mesoscutum, scutellum, metanotum, mesepisternum and propodeum covered with long yellowish-brown erect hairs, on scutellum black hairs intermixed.
