Promethes nigriventris ( Thomson 1890, Promethus )

Diagnosis. Fore wing length 4.6–5.9 mm. Antenna with 20–21 flagellomeres in both sexes, first flagellomere 3.2–4.4 times longer than wide; in males with narrow, long tyloids on flagellomeres 6/7 to 10. Face without a sulcus between compound eye and base of mandible, at most with a change in sculpture instead. Mesopleuron with punctures weak, distinct at most on lower half. Propodeum with basal area more than 2.5 times wider than long, apical carina partly reduced, much weaker than longitudinal carinae; petiolar area mostly smooth, with some irregular wrinkles close to its margins. Tergite 2 with longitudinal wrinkles basally, remainder smooth and shining, wrinkles more extended in males. Females with metasoma laterally compressed and tapered from tergite 3 to apex.

Colouration of females. Antenna black. Head and mesosoma black, face sometimes with a small yellow central face patch, yellow on part of clypeus, mouthparts, hind corner of pronotum, tegula, subtegular ridge, and upper mesepimeron; usually with very large yellow shoulder marks that stretch across the notauli; scutellum mostly yellow. Legs orange, coxae orange, fore coxa sometimes yellow; femora orange; hind tibia white with a dark apex, usually without a subbasal dark band, hind tarsus dark, first segement white basally. Metasoma black.

Colouration of males. As in females but with yellow ventrally on scape and pedicel, antenna often orange below, yellow over entire face, propleuron, often large shoulder mark, varying portions of epicnemium and mesosternum, often lower mesopleuron; scutellum usually black but rarely with light spots on basolateral corners. Coxae usually yellow, hind coxa sometimes partly orange. Metasoma with yellow anterolateral spots on tergites 3 and sometimes 4.
