Diagnosis
Moderately small; mostly black with metasoma mostly yellowish-orange from tergite 3; apex of femora pale dotted; face densely punctate, sculpture smoother on remainder of head; inner margins of eyes subparallel; clypeus transverse; malar line very short; antenna with 30 flagellomeres; mesosoma mostly coarsely punctate, including scutellum and entire speculum, pronotum hardly smoother postero-dorsally; propodeum with carination thick, area basalis petiolate; ovipositor moderately long, apically strongly sinuous. Male unknown.
Differential diagnosis
Moderately small and mostly black; differentiated from all other Pristomerus species by the combination of the very short malar line, the entirely punctate speculum and almost entirely sculptured pronotum, and the very weak female femoral tooth. It appears closely related to P. mbaka sp. nov. in which the scutellum is impunctate and the ovipositor is significantly shorter, apically straight.
