Episemura diodon Kasparyan & Manukyan 1987

Diagnosis. Fore wing length 5.0– 5.4 mm. Female antenna with 15, male antenna with 18 or 19 flagellomeres, in the latter with short and narrow tyloids on flagellomeres 6 to 9/10. Mandible with upper tooth not subdivided, thus bidentate. Propodeum with a full set of carinae enclosing basal, lateral and petiolar areas. Hind margins of tergites 4 to 6 concave, metasoma very strongly laterally compressed from apex of third tergite. Hind tibia dark brown.

Colouration of females. Antenna black. Head and mesosoma black, face with a small yellow central face patch, yellow on clypeus and mouthparts, hind corner of pronotum, tegula, subtegular ridge, and upper mesepimeron; scutellum black. Legs orange, coxae black, fore coxa with a yellow apex; femora orange; hind tibia brown, hind tarsus dark. Metasoma black.

Colouration of males. As in females but with yellow ventrally on antenna, entire face. Fore coxa often largely yellow, hind tibia more orange than brown, apex dark.
