Figures 24 , 26 Etymology. This name refers to the two dark colouration of this species. Description. Fore wing length 3.0– 3.5 mm ( holotype : 3.5 mm ). Antenna with 29–31 (31) 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 with parallel, diagonal carinulae. Metapleuron with juxacoxal carina weakly indicated by some rugae. Propodeal areas smooth with strong punctures. Hind coxa coriaceous and matt, with weak punctures. Hind femur length to width ratio 3.2–3.75 in male and 4.8–5.1 (4.8) in female, ventrally with a small tooth at most half as long as width of hind tibia at mid length. Hind tibia 1.0– 1.25 mm . Second tergite 1.9–2.1 (1.9) × longer than wide at base, smooth and shining. Ovipositor 1.65–1.8 (1.7) × as long as hind tibia. FIGURE 23. Holotype of Pristomerus stellatus sp. nov. A. Habitus and ovipositor tip. B. Face. C. Mesoscutum and head from above. D. Head and mesosoma from lateral. E. Propodeum. F. Metasoma. Scale bars represent 1 mm (A) and 0.5 mm (B, C, D, E, F). Colouration. Antenna basally orange, remainder brown or black; mostly brown or black, but basal and apical segments orange. Head black, orange on clypeus and brown on malar space. Back of head black. Mesosoma including propodeum black; scutellum black with an orange apex. Hind femur dark red-brown, with apex yellow. Hind tibia white or yellow with dark apex and base and often darkened inner side. Fore wing somewhat to strongly infuscate, smoky-brown. Tergite 1 black, brown at base, tergite 2 black, tergites 3 onwards black or brown with wide, light apical bands that are often laterally interrupted by dark round marks. Material examined.
