A second species of goby in the genus Gorogobius has been described from the So Tom Islands in the Gulf of Guinea.
Marcelo Kovai and Ulrich Schliewen name the new species Gorogobius stevcici in a recent issue of the journal Zootaxa.
Gorogobius stevcici can be distinguished from G. nigricinctus, the only other member of the genus, in having an additional laterosensory pore on the head (known as pore), a different arrangement of laterosensory papillae on the head (row g anteriorly ending more or less in front of row o, a transverse interorbital row p present and snout with four median preorbital rows), 37"41 longitudinal scale rows, 22"24 predorsal scales, 9 anal fin rays, 17 pectoral fin rays and overall light reddish-brown body with or without faint brown vertical bands. The new species is named after Zdravko tevi in recognition of assistance rendered to the first author.
Individuals were collected at depths of 15"40 m at Rolas Island (a small island lying south of So Tom Island), typically resting outside small caves.
