Fig. 28View Fig


Moderate size; head whitish yellow with middle of face, frons, inter-ocellar and occiput black; mesosoma and metasoma reddish-testaceous with black markings on mesonotum and propodeum, tergites 1–3 black, and following tergites medially dark brown; face moderately punctate-granulate; inner margins of eyes subparallel; clypeus transverse, sparsely and shallowly punctate; malar line long; antenna with 31 flagellomeres, penultimate flagellomere quadrate; mesosoma densely punctate except pronotum shallowly sculptured, speculum ventrally smooth, and notaulus somewhat rugose; area superomedia elongate; female femoral tooth absent; ovipositor very long, apically strongly sinuous. B 7.2; A 4.4; F 4.9; CT 1.7; ML 0.7; POL 0.6; OOL 1.2; Fl n–1 1.0; ASM 2.0; OT 2.2; FFT 0. Male unknown.

Differential diagnosis

Moderately sized species from Madagascar, mostly reddish-testaceous with basal tergites black, and head mostly white, posteriorly and mid-longitudinally black. Differentiated from most of other Afrotropical species by the absence of a femoral tooth in the female, the white orbits, and the very long ovipositor.

Morphologically related to P. vahaza  , whose clypeus is narrower and mesosoma more slender, and to P. caris  , whose ovipositor is significantly shorter.
