Fig. 17 View Fig


Moderately large; mostly black with fore and mid legs and metasoma from tergite 3 yellowish-orange; trochanters and femora apically white-dotted; pterostigma anteriorly white; face coarsely and densely punctate, sculpture sparser and smoother on remainder of head; malar line moderately long; frons with a strong median protuberance; antenna with 35 flagellomeres; mesosoma densely and coarsely sculptured, punctate to rugose-punctate, including pronotum and almost entire speculum; female femoral tooth nearly absent; ovipositor short, weakly sinuous apically. Male with ocelli slightly enlarged, femoral tooth strong, tergites 3 and following medially black; otherwise similar to female.

Differential diagnosis

Large black species, differentiated from all other Afrotropical Pristomerus by the absence of a femoral tooth in females, the short ovipositor and the strong protuberance on the frons. It is related to P. yangere sp. nov., which lacks the frontal protuberance and has a distinctly longer ovipositor.

Female (holotype)

B 9.3; A 6.1; F 6.2; CT 1.7; ML 0.6; POL 0.8; OOL 0.9; Fl n-1 1.2; ASM 1.7; OT 1.2; FFT 0–1.

COLOUR. Mostly black with metasoma orange from tergite 3 and pale yellow parts on head: a thin margin along frontal orbit, malar space, mandible and palpi; legs testaceous-brown but hind femur black and

all trochanters and femora apically white-dotted; wings slightly infuscate, venation brown, pterostigma anteriorly white.

HEAD. Face mid-longitudinally bulging, coarsely punctate, punctures somewhat confluent into transverse rugosities; clypeus transverse, more sparsely punctate, distinctly convex in profile view, its ventral margin strongly convex; malar line moderately long; frons finely and densely punctate with a strong median protuberance: laterally compressed, about triangular, its tip rounded, about as high as basally wide; vertex and temple coriaceous; occipital carina joining hypostomal carina distinctly above mandible base; antenna with 35 flagellomeres, penultimate one slightly elongate.

MESOSOMA. Mesosoma elongate; entire pronotum, mesopleuron and metapleuron densely and deeply punctate, with a deep oblique striate furrow below speculum, speculum almost entirely punctate; mesonotum similarly punctate with punctures on apex of mesoscutum confluent into coarse transverse rugosities; notaulus strongly impressed; posterior vertical face of scutellum longitudinally striate; propodeum coarsely rugose punctate, carination thick, area superomedia not carinate laterally beyond anterior transverse carina. Legs. Femoral tooth nearly absent, reduced to a weak subapical protuberance followed by minute denticles.

METASOMA. Tergite 2 and apical half of tergite 1 longitudinally aciculate, following tergites coriaceous; thyridium subelliptic and wide with main axis longitudinal; ovipositor relatively short, slightly downcurved, apically slightly swollen and weakly sinuous.

Male (paratype)

B 9.1;A 6.0; F 5.5; POL 0.5; OOL 0.6. Ocelli slightly enlarged; frontal protuberance present but distinctly smaller than basally wide; area superomedia fully carinate and slightly more elongate; femur swollen, femoral tooth and following denticles strong; tergite 3 and following medially black; otherwise similar to female.
