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

Head whitish yellow with frons, inter-ocellar area and occiput black; mesosoma testaceous–orange; metasoma black with apical margin of tergites 2–7 white; antenna basally black, fading to pale testaceous, then apically darker; face densely and shallowly punctate; inner margins of eyes subparallel; clypeus transverse, sparsely punctate; malar line long; occipital carina joining hypostomal carina shortly above mandible base; antenna long with 35–36 flagellomeres, penultimate flagellomere quadrate; mesosoma elongate, very densely punctate-granulate except pronotum centrally and speculum ventrally smoother, and mesoscutum mid-posteriorly transversely rugose; area superomedia elongate; female femoral tooth about as long as basally wide; ovipositor moderately long, weakly sinuous apically. B 6.2–9.2; A 4.7– 6.9; F 4.9–7.1; CT 1.8; ML 0.7; POL 0.7; OOL 0.4; Fl n–1 1.0; ASM 2.5; OT 1.4–1.5; FFT 1–2. Male with ocelli and femoral tooth enlarged, posterior ocellus almost touching eyes dorsally; otherwise similar to female. OOL 0.1; POL 0.4.

Differential diagnosis

Rather large Madagascan species, differentiated from all other Afrotropical species by the atypical colour pattern: head mostly white, mesosoma testaceous orange and metasoma mostly black with apical margins of tergites white. The only other Afrotropical species with a somewhat similar colour pattern is P. zulu sp. nov., whose face is medially reddish-testaceous and the malar line is distinctly shorter.
