Subtribe Pericopina

Nomenclature follows Watson and Goodger (1986).

Dysschema marginalis (Walker, 1855)

Identification by comparison with the holotype ( NHMUK, Venezuela) and NHMUK series. My Tobago specimen is considerably smaller than Venezuelan material of the same species. This species shows strong sexual dimorphism ; the female having the dorsal forewing brown with a broad pale bar, and dorsal hindwing orange with a dark margin. No records from Trinidad.
