The family Turridae s.l. (Mollusca, Gastropoda) in Angola (West Africa), 1. Subfamily Daphnellinae

A total of 12 species belonging to the subfamily Daphnellinae (family Turridae s.l.) and collected from the coast of Angola have been studied. Six of these species are described as new, and the other six are recorded for the first time from Angola (Diaugasma marchadi, Raphitoma cordieri, R. purpurea, R. leufroyi, Kermia alveolata and Gymnobela dautzenbergi). The supraspecific taxa Diaugasma, Philbertia, Raphitoma, Clathurella, Daphnella, Cythara, Propebela, Pleurotomoides, Kermia and Gymnobela are commented on or discussed. In addition, Cordieria, Pseudodaphnella and Asperdaphne are considered as synonyms of Raphitoma, and Clathurina a synonym of Kermia. Diaugasma is raised to generic level, Kermia is considered to be present in the Atlantic ocean, and the taxa Kermia alveolata and K. meheusti are considered to be conspecific. Some comments are made on the geographic distribution of the turrid fauna of Angola.
