Gastrallus cervelloi sp. n. de la isla de Bioco, Guinea Ecuatorial (Coleoptera, Anobiidae)

Abstract

Gastrallus cervelloi n. sp. is now described from Bioko lsland (Equatorial Guinea), tropical African region. This new Anobiinae belongs to the G. pubens Fairmaire, 1875 section due to the morphology of the aedeagus. It is easily distinguished from G. pubens and G. vinyolasi Español, 1992, by the antennae, prothorax, striae of the elytra and aedeagical morphology (parameres, parameres lobe and median lobe). New data are provided on the Megorama modestum (Pic, 1950) and on the Mesocoelopus castaneus Español, 1967.
