Abstract

This work concerns the Coleoptera Hydradephaga collected in several sites of the Moukalaba - Doudou National Park and in external zone North of the Park. In the Park 107 species have been collected, 109 species in external zone. The Authors describe 7 new species of Dytiscidae: Hydrovatus rigatoi n. sp. (confossus group) chiefly distinguishable for shape of penis; Bidessus mboyei n. sp. (sharpi group, ovoideus subgroup) close to B. ovoideus Régimbart, 1895 and B. seydeli Biström, 1885, distinguishable for smaller size and for shape of penis; Clypeodytes acutipenis n. sp. close to C. densepunctatus Biström, 1988, distinguishable for apex of penis clearly pointed; Laccophilus sinuosipenis n. sp. (deceptor group) close to L. bizonatus Régimbart, 1895, distinguishable for sinuous shape of penis; Laccophilus cianferonii n. sp. (deceptor group) close to L. bilardoi Pederzani and Rocchi, 1982, chiefly distinguishable for shape of penis; Copelatus bapounouensis n. sp. (erichsonii group, atrosulcatus subgroup) close to C. ellai Bilardo and Rocchi, 1995, chiefly distinguishable for shape of penis; Copelatus gigas n. sp. (erichsonii group, vigintisulcatus subgroup) close to C. fasciatus Bilardo and Rocchi, 1995, chiefly distinguishable for large size and for shape of penis.
