Resum

Three new Gastrallus Jacq. du Val (Coleoptera, Anobiidae) from Central Africa
Three new species of the genus Gastrallus Jaq. du Val are described, two (Gastrullus degallieri n. sp. and Gastrallus vinyolasi n. sp. from the Republic of Central Africa and one (Gastrallus ribesi n. sp.) from Equatorial Guinea. The classification of the members of this genus is difficult because most species are very similar in extemal morphology, nevertheless the conformation of the aedeagus is important to separate them.
