Abstract

Species in the family Cerithiopsidae are spongivores that live in all oceans from the littoral to the upper bathyal zone. This paper discusses the cerithiopsid species that were collected during the Dutch expeditions CANCAP-VI (1982) and CANCAP-VII (1986) to the Cape Verde archipelago. Fourteen species were identified in the cancap samples. Six new species of Cerithiopsis are proposed: C. sal spec. nov., C. luzia spec. nov., C. vicente spec. nov., C. cima spec. nov., C. boavista spec. nov. and C. saotiago spec. nov. Five existing species of the genus Cerithiopsis Forbes & Hanley, 1850 were redescribed and illustrated: Cerithiopsis laurauae, C. albae, C. carmelae, C. chechoi and C. eolo. The identification of one species was uncertain: Cerithiopsis cf. diadema. In addition, a new species is described in the genus Dizoniopsis Sacco, 1895: D. razo spec. nov. Cerithiopsis leopoldoi Espinosa & Ortea, 2021 is placed in the genus Dizoniopsis. The cerithiopsid species in our material are distributed throughout the archipelago; the oceanic gaps between the islands (10 – 100 km) have not been a barrier in the distribution of the species. None of the cerithiopsid species known from the Cape Verde archipelago have been found on the NW African coast, the Canary Islands, Madeira, the Azores or Ascension. A high degree of endemism is likely for the cerithiopsids from the Cape Verde archipelago.

Abstract

Calliostoma cancapae sp. nov. is described from the Cape Verde Islands. Empty shells of the new species were collected from 41 sites in the depth range 35-3250 m during the CANCAP-vi (1982) and CANCAP-vii (1986) expeditions.
