Letis

Abstract: An illustrated and annotated catalogue is presented of 17 species of the tribe Thermesiini (Lepidoptera, Erebidae, Erebinae) confirmed to occur in Trinidad, of which Hemeroblemma dolon (Cramer), H. helima (Stoll), H. malitiosa (Guenee) H. ochrolinea (Guenee), Feigeria mycerina (Cramer) and ‘Letis’ arcana Feige are new records for the island. Seven species are recorded from Tobago, two for the first time. Images of 14 species of living adults are included. Almost nothing has recorded regarding food plants and early stages of Thermesiini in Trinidad, but known food plants from elsewhere in the Neotropics are tabulated.
