Phthorima xanthaspis ( Thomson 1890, Homotropus )

Diagnosis. Fore wing length 4.1–5.6. Antenna in females with 17–18 flagellomeres, in males with 19 flagellomeres and with narrow, long tyloids on flagellomeres 7 to 13/14. 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. Propodeum with carination incomplete. Second metasomal tergite 1.0–1.4 times longer than wide, with punctures and coriaceous sculpture surpassing basal half, third tergite punctate and with coriaceous sculpture on its entire length.

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

Colouration of males. As in females but with yellow ventrally on antenna, entire face, propleuron, large shoulder mark often with the inner corner extended over part of mesoscutum, varying proportion of epicnemium, mesosternum, and a broad stripe on lower mesopleuron. Fore and mid coxae largely yellow. Metasoma often with yellow marks basolaterally on third tergite.
