Homotropus tauriscorum Strobl 1903 

Diagnosis. Fore wing length 4–4.5 mm. Antenna of both sexes with 21 flagellomeres; in females, apical flagellomeres with multiporous plate sensilla also present ventrally; in males with broadly oval, smooth and shining tyloids on flagellomeres 7 to 13 / 14. Face strongly coriaceous, punctures disappearing against the background sculpture. Clypeus weakly excised, with lobes rounded. Mesopleuron coriaceous and weakly punctate on lower half, smooth and shining on upper half. Mesoscutum smooth and shining, punctures restricted to front half and margins, often weak. Hind coxa with hind surface very strongly coriaceous and matt. Fore wing areolet open. Propodeum with carination complete although sometimes almost disappearing against the very strongly rugose background. Female metasoma dorsoventrally depressed. First tergite with median dorsal carinae present at least basally, often with strong longitudinal wrinkles, 1.3 times as long as wide in females, 1.6–1.9 in males; second tergite basally with few longitudinal wrinkles, more so in males, 0.6 times as long as wide in females, 0.8–0.9 in males, second tergite 0.7–0.9 times length of first tergite; spiracle of third tergite on dorsal part, above lateral fold.

Colouration of females. Antenna black. Head and mesosoma black, with yellow on central face patch separated from yellow on clypeus, yellow on mouthparts, hind corner of pronotum, tegula, subtegular ridge, large shoulder mark, upper mesepimeron, scutellum laterally. Legs yellow, all coxae black, fore and mid coxae with yellow apices, femora yellow or orange with a ventral black stripe, hind tibia yellow with a dark apex and subbasal spot, hind tarsus dark. Metasoma black, tergites 3–4 and apex of tergite 2 all or mainly orange.

Colouration of males. As in females but additionally with yellow over entire face, scape and pedicel ventrally, propleuron, mesosternum and a spot or stripe on lower mesopleuron, all of fore and mid coxae; metasoma as in female or black with often yellow or orange basal spots and usually with orange hind margins on tergites 3, 4 and 5.
