B 7.0–8.4; A 3.8–4.6; F 3.6–4.3; CT 2.1; ML 0.7; POL 0.9; OOL 1.2; Fl n–1 1.1 ; ASM 2.0; OT 1.8–2.1; FFT 1. Male with mesoscutum weakly sculptured, mostly coriaceous, inner margins of eyes distinctly diverging ventrally, ocelli enlarged, femur and femoral tooth strongly stouter. POL 0.6; OOL 0.4. Differential diagnosis Rather small, overall yellow to yellowish orange with metasoma basally black; differentiated from all other Afrotropical species by the combination of the rather strongly transverse clypeus, the long malar line, the small female femoral tooth and the markedly long ovipositor. Morphologically close to other Pristomerus species in Madagascar : P. kelikely and related species, which have a shorter malar line and no femoral tooth in the female; P. patator , which is distinctly larger with longer antennae and an incompletely carinate area superomedia; and the widespread P. pallidus , which has a shorter ovipositor and nearly always a differently coloured mesosoma with the notaulus and the scutellum paler than the remainder of the mesonotum. Pristomerus roberti is otherwise probably closely related to P. herero sp. nov. (see differential diagnosis of P. herero sp. nov. ). Fig. 31. Pristomerus roberti Rousse, Villemant & Seyrig, 2013 .
