Diagnosis

Males and females of R. namaquaensis sp. nov. can be separated from other Redivivoides species by their black to brown metasomal terga in combination with dark brown to black prepygidial fimbria and orange-brown pygidial fimbria ( Figs 10D , 11C ).

Malar area medially narrow, almost linear. Antenna black, ventrally dark 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. 10C ). Mesoscutum, scutellum, metanotum, mesepisternum and propodeum covered with long yellowish-brown erect hairs, on the mesoscutum black hairs intermixed ( Fig. 10C ).

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 yellowish-brown.

METASOMA. Integument dark brown to black, apical margins of terga narrowly translucent reddish to yellowish-brown ( Fig. 10D ). T1 – T4 covered with erect yellowish-white hairs, becoming progressively shorter from T1 to T4; apical tergal hair band sparse on T1, on T2 – T4 broadly white ( Fig. 10A, D ). Prepygidial fimbria dark brown to black, pygidial fimbria orange-brown. Terga impunctate, finely shagreened and matt ( Fig. 10D ).
