Diagnosis

Males and females of R. capensis sp. nov. can be separated from other Redivivoides species by their extensively and brightly red metasomal terga ( Figs 2D , 3C ) in combination with an impunctate and densely shagreened scutum ( Figs 2C , 3B ).

Etymology

Named after the Cape of Good Hope (“the Cape ”).

Female

BODY LENGTH. 9.0- 10.5 mm.

HEAD. Head slightly wider than long. Integument black except tips of mandible partly dark reddishbrown. Face sparsely covered with long, whitish-grey to brown, erect hairs intermixed with black hairs especially along the inner eye margins and on vertex ( Fig. 2B ). Clypeus mostly flat, apically almost impunctate; medially covered with medium-sized punctures that become gradually smaller and denser towards the lateral and upper margins; surface between punctures shiny ( Fig. 2B ). Malar area medially narrow, almost linear. Antenna black, ventrally orange to reddish-brown.

MESOSOMA. Integument black. Mesoscutum impunctate, finely shagreened and matt ( Fig. 2C ). Mesoscutum, scutellum, metanotum, mesepisternum and propodeum covered with long yellowishbrown erect hairs, on the disc of mesoscutum some black hairs intermixed.

WINGS. Yellowish-brown; wing venation dark brown.

LEGS. Integument black to dark reddish-brown. Vestiture of femora whitish-yellow, on tibiae and tarsi dark brown to black, scopae dark brown, ventrally hairs white to greyish-yellow.

METASOMA. Integument black, except T1 to a variable extent apically red, T2 red with a black spot anterior-medially, T3 apically with a red margin ( Fig. 2D ). T1 completely and T2 on disc sparsely covered with a few 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. 2A, D ). Prepygidial fimbria dorsally black, laterally partly white, pygidial fimbria black. Terga impunctate, finely shagreened with a silky shine ( Fig. 2D ).

LEGS. Integument black, tibiae and tarsi partly dark red-brown. Vestiture whitish.

METASOMA. Integument black, except T1 to a variable extend apically red, T2 red with a black spot anterior-medially, T3 either like T2 or in some specimens only apically with a red margin, T 4 in some males with red basal and apical margins ( Fig. 3C ). T1 completely and T2 – T3 on disc sparsely covered with a few long erect yellowish-white hairs; T4 – T6 covered with short black hairs; apical tergal hair band missing on T1, on T2 – T5 narrow and sparsely white ( Fig. 3C ). Terga impunctate, finely shagreened with a silky shine ( Fig. 3C ).
