Diagnosis

Moderately small to small; yellowish-orange with mandible, clypeus and frontal orbits pale yellow, and variable dorsal black markings; trochanters and femora apically white-dotted; fore wing with anterior edge of pterostigma whitish; face densely punctate-granulate, clypeus almost entirely smooth, remainder of head coriaceous; clypeus strongly transverse; malar line short; antenna with 27 flagellomeres, penultimate one quadrate; mesosoma moderately to densely punctate, including sometimes pronotum and almost entire speculum, with punctures confluent into rugosities on notaulus; propodeal carination thick; female femoral tooth absent; ovipositor short, apically nearly straight. Male unknown.

Differential diagnosis

Small to moderately small and yellow to yellowish orange overall with some black markings dorsally; differentiated from all other Afrotropical species by the combination of the short malar line, the absence of a femoral tooth and the short ovipositor. Pristomerus zande sp. nov. is somewhat morphologically similar to P. albescens and P. vahaza , but is easily differentiated because both have a narrower clypeus.

COLOUR. Yellowish-orange overall with mandible, clypeus and frontal orbits pale yellow, and variable black markings: frons, occiput laterally, vertex, flagellum, apex of tergite 1 and a variable basal part of following tergites; ovipositor sheath, hind tarsus, and apex and base of hind tibia infuscate; trochanters and femora apically white–dotted; wings hyaline, venation brown, pterostigma anteriorly white.

HEAD. Face densely and shallowly punctate-granulate; inner margins of eyes slightly converging ventrally; clypeus almost smooth, strongly transverse, distinctly convex in profile view; malar line short; frons, vertex and temple coriaceous; frons with a weak mid-longitudinal carina; occipital carina joining hypostomal carina shortly above mandible base; antenna with 27 flagellomeres, penultimate flagellomere quadrate.

MESOSOMA. Moderately elongate; entire pronotum moderately and shallowly punctate (postero-dorsally smooth in the smallest paratype); mesopleuron and metapleuron very densely punctate-granulate, with a strong oblique striate furrow below speculum, speculum almost entirely shallowly punctate; mesonotum densely punctate, punctures confluent into fine transverse rugosities along notaulus; notaulus moderate; propodeal carination complete and thick, area petiolaris transversely strigose. Legs. Femoral tooth absent.

METASOMA. Tergite 2 and apical half of tergite 1 longitudinally aciculate, following tergites sparsely and shallowly punctate-granulate; thyridium subcircular; ovipositor moderately short, stout, apically slightly swollen and nearly straight.
