Diagnosis

Large; black with metasoma orange from tergite 3; trochanters and apex of femora white-dotted; pterostigma anteriorly white; face densely punctate-granulate; clypeus more sparsely punctate, transverse; malar line long; remainder of head finely and densely punctate; antenna with 32–35 flagellomeres, penultimate flagellomere quadrate; mesosoma coarsely punctate with middle of pronotum and ventral half of speculum smooth, and propodeum punctate-rugose; female femoral tooth absent; ovipositor long, strongly sinuous apically. Male unknown.

Differential diagnosis

Large and black with metasoma partially orange; differentiated from all other Afrotropical species by the combination of the colour pattern, the large size and the absence of a female femoral tooth; it might be closely related to P. kuku sp. nov., which is, however, characterized by a strong frontal protuberance and a distinctly shorter ovipositor.

COLOUR. Head black with lighter pale yellow to yellowish parts: clypeus, mandible, palpi, malar space and frontal orbits; mesosoma black with tegula pale yellow; tergites 1–2 black, following tergites orange; fore and mid legs yellowish-orange; hind leg basally black, strongly infuscate from femur; all trochanters and femora apically white-dotted; antenna and ovipositor sheath dark brown; wings slightly infuscate, venation brown, pterostigma anteriorly white.

HEAD. Face densely punctate-granulate; inner margins of eyes subparallel; clypeus transverse, sparsely punctate but punctation denser along dorsal margin, distinctly convex in profile; malar line long; frons, vertex and temple finely and densely punctate; frond with a moderate mid-longitudinal ridge from median ocellus to upper face; occipital carina joining hypostomal carina at mandible base; antenna with 35 flagellomeres, penultimate flagellomere quadrate.

MESOSOMA. Moderately stout; pronotum densely and finely punctate with a smooth median area; mesopleuron and metapleuron densely punctate with an oblique striate furrow below speculum, speculum ventrally smooth; mesoscutum densely and coarsely punctate-granulate, punctures confluent into transverse rugosities along notaulus; notaulus deep; scutellum densely punctate, its posterior vertical face longitudinally striate; propodeum coarsely punctate-rugose, laterally punctate; carination thick. Legs. Femoral tooth totally absent.

METASOMA. Tergites 2–3 and apical half of tergite 1 longitudinally aciculate, following tergites coriaceous; thyridium elliptic and wide with main axis oblique; ovipositor long, slightly down-curved, apically strongly sinuous.
