Abstract
Two new Brazilian species of the genus Coelocephalapion Wagner, 1914 placed in the C. nodicorne species-group (Brentidae: Apioninae) reared from Euphorbiaceae are described and illustrated: Coelocephalapion paleariae sp. n. (Type locality: Botucatu, São Paulo state; reared from seeds Croton glandulosus L.) and Coelocephalapion geraldinhoi sp. n. (Type locality: Dores do Indaiá, Minas Gerais state; reared from leaf galls on Croton antisyphiliticus Mart.). Aside from species descriptions, we also provide a key to species of the C. nodicorne species-group.
