Gobius sp. aff. rubropunctatus Delais, 1951
ZSM 34187 (1 specimen), on white sand in 3 m depth, Ilhéu das Cabras, São Tomé; ZSM 34731 (2 specimens), north coast of Principe Island. SMNS 24246 (3 specimens) from Bom Bom Islet; ZSM 34729 (1 specimen) from Lagoa Azul. This species is close to G. rubropunctatus ZBK but differs in details of the head sensory papillae pattern and possibly represents a new species. However, identification depends on inspection of typematerial of G. rubropunctatus ZBK and G. senegambiensis ZBK. This is a common species on soft bottoms at Príncipe and São Tomé, from about 5 m downwards. Territorial males are darker than females (Figure 19 and 20). A photograph of a male of this species is given in Wirtz (2005a) under the name Thorogobius angolanus .
