Homotropus vitreus Dasch 1964 a Diagnosis. Fore wing length 3.4–4.3 mm. Antenna of both sexes with 20 to 21 flagellomeres; in females, apical flagellomeres with multiporous plate sensilla also present ventrally, although sparse; in males with narrow, short or long and sometimes hardly visible tyloids on flagellomeres 8 to 10 / 11. Face strongly coriaceous, punctures disappearing against the background sculpture. Clypeus weakly excised, with lobes somewhat angulate at outer corners. Mesopleuron mainly smooth and shining, with very weak and irregular sculpture and punctures on lower half. Mesoscutum entirely smooth and shining, completely unsculptured except for some punctures along anterior margin. Hind coxa with hind surface strongly coriaceous and matt. Fore wing areolet closed, vein 3 rs-m unpigmented, veins of very light colour. Propodeum with pleural carina and apical part of lateral longitudinal carina present and strong, remaining carinae usually at least indicated by strong rugae; rugose, smoother on petiolar area. Female metasoma dorsoventrally depressed. First tergite with median dorsal carinae present only basally or sometimes surpassing middle of tergite, with some longitudinal wrinkles laterally, 1.4–1.75 times longer than wide; second tergite basally and laterally with some strong longitudinal wrinkles, 0.7–0.9 times as long as wide, second tergite 0.8–0.9 times length of first tergite; spiracle of third tergite on dorsal part, above lateral fold. Colouration of females. Antenna bright orange. Head and mesosoma black, with yellow on central face patch which is broadly separated from yellow on clypeus, yellow on mouthparts, hind corner of pronotum, tegula, subtegular ridge, large shoulder mark, upper mesepimeron; scutellum black. Legs orange, fore and mid coxae yellow with dark bases, hind coxa black on basal half, yellow apically, femora orange, hind tibia orange, hind tarsus usually not dark. Metasoma black, tergites 2 partly, 3–4 all or mainly orange. Colouration of males. As in females but additionally with yellow over entire face, antenna ventrally, part of propleuron, epicnemium and a stripe on lower mesopleuron, all of fore and mid coxae, and often basal spots or bars on tergites 3 and 4.
