Abstract:
Prasmodon zlotnicki, a new Costa Rican species of the genus Prasmodon Nixon, is described and
illustrated. In addition, the first host records for the genus are included along with an updated key
to differentiate Prasmodon zlotnicki from P. eminens Nixon. Prasmodon is now known to attack
several species of leaf-rolling and leaf-webbing Crambidae (Lepidoptera) in rain forest habitats.
