Secondo contributo alla conoscenza dei Brentidae (Insecta, Coleoptera) dell'Africa orientale

The author lists 15 species belonging to 26 genera of East Africa Brentidae. Three new species are described: Gynandrorhynchus somaliensis n. sp. from Somalia (holotypus in the Museo Regionale di Scienze Naturali, Turin) - compared to the closely allied G. bocandei Lacordaire, G. corneolus (Kleine) and G. granulatus (Kleine); Amorphocephala aethiopica n. sp. from Ethiopia (halotypus in the Museo Regionale di Sienze Naturali, Turin) - compared to the closely related Amorphocephala poweri De Muizon; Plesiobolbus martini n. sp. from Tanzania (holotypus in the Zoologisk Museum, Copenhagen) - compared to P. sagax Kolbe and P. cribriceps (Kolbe). The validity of the genus Plesiobolbus Kolbe is confirmed.
