Description
Pristomerus roberti Rousse, Villemant & Seyrig, 2013
Fig. 31
Diagnosis (range of variation from Rousse et al. 2013)
Moderately small; yellow to yellowish-orange overall with tergites 1–3 variously blackened; frons, face and clypeus moderately densely punctate-granulate, remainder of head coriaceous; inner margins of eyes subparallel; clypeus strongly transverse; malar line long; occipital carina joining hypostomal carina shortly above mandible base; antenna with 28–32 flagellomeres, penultimate flagellomere subquadrate; mesosoma moderately elongate and densely punctate but pronotum dorsally and ventral half of speculum smooth; female femoral tooth small, followed by minute denticles; ovipositor long, its apex distinctly sinuous. 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 diagnosisRather 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.).
Material examinedHolotype MADAGASCAR: ♀, “ MADAGASCAR, Bekily [Ampandrandava], reg. sud de l’île, III. 33, EY 0000003511” (MNHN).
