Pristomerus atriceps Girault Description. Fore wing length 4.1–5.6 mm (holotype: 5.5 mm). Antenna with 33–35 flagellomeres. Mesoscutum with only a few punctures along front margin and sometimes along notauli. Scutellum without punctures, all smooth and shining. Mesopleuron with strong and rather dense punctures, smooth in-between; below subtegular ridge smooth and with a few punctures and often with a few parallel, diagonal carinulae. Metapleuron with juxacoxal carina distinct on most of its length, although often weaker medially. Propodeal areas smooth with strong punctures to rugulose in part. Hind coxa coriaceous and matt, with weak punctures. Hind femur length to width ratio 3.5–3.6 in male and 3.2–3.7 in female, ventrally with a large tooth that is longer than width of hind tibia at mid length, and adjacent smaller teeth. Hind tibia 1.5–1.9 mm. Second tergite 1.9–2.0 × longer than wide at base, smooth and shining. Ovipositor 1.7–1.9 × as long as hind tibia.

Colouration. Antenna uniformly brown or black. Face black or dark brown, sometimes with orange inner eye margins and orange on malar space. Clypeus dark with apex orange. Back of head black or dark brown. Mesosoma including propodeum entirely orange. Hind femur orange, with apex yellow. Hind tibia orange-brown with base and apex broadly darkened, or mostly dark. Fore wing somewhat infuscate, brown. Tergites 1–4 or 5 orange, remainder black or dark brown with light, narrow hind margins, in male often with dark apex more expanded.

Notes. P. g i r a ul t i is a new name for the secondary homonym Pristomerus atriceps Girault (cit. Townes, Townes, Gupta).
