Diagnosis (range of variation from Rousse et al. 2013)

Background colour yellowish-orange with some median dark spots on metasomal tergites; face densely punctate; inner margins of eyes subparallel; clypeus transverse, very sparsely punctate, inter-puncture spaces smooth; malar line long; remainder of head coriaceous; occipital carina joining hypostomal carina shortly above mandible base; antenna very long with more than 37–38 flagellomeres, penultimate flagellomere elongate; mesosoma moderately elongate, moderately to densely punctate, but pronotum and speculum almost entirely smooth and scutellum distinctly more sparsely punctate than mesoscutum; area superomedia weakly delimited laterally beyond anterior transverse carina; female femoral tooth small, followed by some minute denticles; ovipositor long, slightly sinuous apically. B 7.8–10.1; A 5.3– 6.9; F 5.9–7.5; CT 1.8; ML 0.7; POL 0.7; OOL 1.1; Fl n–1 1.2; ASM 2.0; OT 1.8–1.9; FFT 1. Male with inner margins of eyes diverging ventrally, and ocelli, hind femur and femoral tooth enlarged. B 8.9–9.8; A 5.8–7.1; F 6.3–6.7: POL 0.6; OOL 0.4.

Differential diagnosis

Large yellowish-orange species from Madagascar; differentiated from all other Pristomerus   species in the region by the combination of the large size, the antenna with numerous flagellomeres, the long malar line, the largely smooth speculum, the punctation on the scutellum, which is often distinctly sparser than on the mesoscutum, the area superomedia hardly delimited postero-laterally, the small female femoral tooth and the long ovipositor.
