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
), prepygidial and pygidial fimbria dark brown to black (
Fig. 7D
). These characters also apply to males (
Fig. 8C
) but the genitalia and S6 – S8 (
Fig. 8
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
). 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
). 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
). Mesoscutum, scutellum, metanotum, mesepisternum and propodeum covered with long yellowish-brown erect hairs, black hairs intermixed on mesoscutum (
Fig. 7C
).
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
). 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
). 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
).
