Two new species of Gonocephalum: Gonocephalum marylinneae n. sp. from Madagascar, and Gonocephalum moraguesi n. sp. from Kenya, and Pachypterus girardi n. sp. from Madagascar are described. G. camerunense Gridelli, 1945 is recorded from Ivory Coast. G. marylinneae n. sp. is characterised by facies similar to G. dermestoides pupieri Chatanay, 1913, but smaller protibiae, G. moraguesi n. sp. is similar to G. simplex (Fabricius, 1801), but the ratio pronotal/elytral length is 1.4, not 1.3 as in G. simplex. Pachypterus girardi n. sp. is characterised by simple, not dentate legs and apically pointed aedeagus.
