Ptenos leucopodus (Cameron)

Sericocera leucopoda Cameron, 1883: 48, pl. 3, fig. 3.

Hemidianeura leucopoda : Smith 1992: 120.

Ptenos leucopodus : Taeger et al. 2010: 169.

Remarks.

Specimens in USNM from Venezuela bear a label "caterpillar on Inya sp." ( Smith 1992). This is probably a misspelling for Inga . Ptenos occurs from southwestern United States and Dominica to Argentina; about 31 species are known, which were keyed by Smith (1992) under the name Hemidianeura . Host plants are not known for the other species.

Distribution.

Costa Rica, Ecuador, Guyana, Honduras, Mexico (Chiapas, San Luis Potosi, Tabasco, Veracruz), Panama, Surinam, Venezuela ( Smith 1992).

Food plant and biology.
