Gobiid fishes from the Cape Verde Islands,including two new species of Gobius (Teleostei: Gobioidei)

Ten species of gobiid fishes (Teleostei: Gobioidei) now listed from the Cape Verde islands fall into several zoogeographical categories, including tropical West African Bathygobius casamancus, Mauligobius nigri, Porogobius schlegelii (unconfirmed) and Vanneaugobius canariensis, tropical amphiatlantic B. soporator and Gnatholepis thompsoni, and Canarian Didogobius kochi. Two new species of the eastern Atlantic, predominantly temperate genus Gobius are described: G. ateriformis sp. nov. and G. tetrophthalmus sp. nov., known so far only from the Cape Verdes, but reported occurrence of the congeneric Atlantic-Mediterranean G. paganellus has not been confirmed. The pattern of free neuromast organs (sensory papillae) of the head lateral-line system in Mauligobius nigri and the habitat of this species are described for the first time and its distribution further discussed. Diversity of gobies and other inshore fishes at the Cape Verdes is briefly indicated.
