Phthorima compressa ( Desvignes 1856, Bassus )

Bassus ibalioidis Kriechbaumer 1878

Homotropus niger Morley 1906

Diagnosis. Fore wing length 3.5–4.8 mm. Antenna in females with 17 to 18 flagellomeres, in males with 19 to 20 flagellomeres and with narrow, long tyloids on flagellomeres 7 to 14 / 15. Face without a sulcus between compound eye and base of mandible, at most with a change in sculpture instead. Clypeus with a subapical depression, rendering the basal three-quarters convex. Scutellum usually black but sometimes with varying yellow colouration, especially in males. Propodeum with carination complete and strong. Second metasomal tergite at least 1.5–1.7 times longer than basally wide, densely punctate and coriaceous sculpture restricted to basal third, third tergite mostly smooth and shining, with very sparse punctures basally and weakly coriaceous sculpture close to apex.

Colouration of females. Antenna black. Head and mesosoma black, face with or without a very small yellow central face patch, orange on clypeus and mouthparts, yellow on hind corner of pronotum, tegula, and sometimes upper mesepimeron; scutellum black. Legs orange, coxae usually orange, but hind coxa sometimes black; femora orange; hind tibia orange to brown, often somewhat dark apically, hind tarsus dark orange. Metasoma black.

Colouration of males. As in females but with yellow ventrally on antenna, entire face, propleuron, large shoulder mark, subtegular ridge, variable proportion of epicnemium and mesosternum. Scutellum sometimes marked with yellow. Fore and mid coxae largely yellow.
