Pristomerus bullis Fitton in Polaszek et al., 1994: 83 .

Diagnosis

Moderately sized; yellow to orange overall with base of tergite 2 infuscate, frons darker than face, and notaulus and scutellum lighter than remainder of mesonotum; face densely punctate; inner eye margins parallel; clypeus very strongly transverse, sparsely punctate with inter-punctures space smooth; malar line short; frons and vertex punctate-granulate, gena and temple coriaceous; occipital carina joining hypostomal carina shortly above mandible base; antenna with 26–32 flagellomeres, penultimate flagellomere shorter than wide; mesosoma strongly elongate, mostly very densely punctate but dorsal half of pronotum and ventral half of speculum smooth; propodeum with area superomedia narrow and elongate; hind femur rather stout; femoral tooth stout, about half as high as basally wide, followed by minute denticles; ovipositor rather short, apically moderately sinuous. B 7.3–8.3; A 3.5–4.0; F 4.0–4.7; CT 2.2–2.5; ML 0.3; POL 1.0; OOL 1.3; Fl n–1 0.7; ASM 2.8; OT 1.3; FFT 1. Male with inner margins of eyes diverging ventrally, ocelli, hind femur and femoral tooth enlarged, and mesoscutum strongly smoother; otherwise similar to female. POL 0.5; OOL 0.4.

Differential diagnosis

Moderately sized and yellow to orange overall; differentiated from most other Afrotropical species by the very transverse clypeus. It is thus apparently closely related to P. babinga sp. nov. but P. bullis has a significantly shorter ovipositor.
