Type species: Gobius nigricintus Delais, 1951 .
Diagnosis. Gorogobius differs from all other Gobiinae genera in the Atlantic and the Mediterranean by the following combination of characters: (1) suborbital papillae without row a; (2) presence of only anterior oculoscapular head lateral-line canal; (3) chin lacking barbels; (4) cheek scaled; (5) six transverse suborbital rows of sensory papillae, row b short, meeting row 5, row 6 with no inferior section, row 7 represented by one papilla; (6) pectoral fin with uppermost rays enclosed by fin-membrane; (7) pelvic fin elliptical, with truncate rear edge, anterior membrane well developed.
Description. Body moderately elongate. Eyes dorsolateral, with interorbital space about one third of eyediameter; cranial roof covered by dorsal axial musculature; snout rounded in dorsal view; anterior nostril tubular, without process from rim and posterior nostril with low tubular edges, on border of orbit, chin lacking barbels; mouth oblique, jaws subequal, with posterior angle below anterior edge of orbit; upper lip width uniform; teeth in jaws erect, caniniform, in several rows medially, in upper jaw outer row enlarged and spaced; in lower jaw outer row and lateral teeth of inner row enlarged; tongue truncate; with slight median emargination and rounded corners; branchiostegal membrane attached along entire lateral margin of isthmus, from immediately anterior to pectoral margin. Pectoral girdle without dermal flaps on anterior edge.
Pectoral fin with uppermost rays enclosed by fin-membrane; pelvic fin complete, with well-developed anterior membrane, without lateral lobes; caudal fin rounded, shorter than head.
Body with ctenoid scales, 29–41 longitudinal scale rows; entire predorsal area (to eyes), cheek, opercle, and breast, with ctenoid scales; uppermost and lowermost scales of caudal peduncle not markedly enlarged.
Vertebrae: 11 + 16 = 27 (paratypes).
First dorsal fin pterygiophore insertion pattern: 3-22110.
Head lateral line system with anterior oculoscapular canal, carrying pores σ, λ, κ, ω, α, ρ, pore β present in one species; suborbital papillae without row a; six transverse suborbital rows of sensory papillae, row b short, meeting row 5, latter with inferior section going below end of row d; row 6 above row b, with no inferior sections, row 7 represented by one papilla; row x¹ extending forwards to pore β, or meeting row n; long anterior dorsal row n behind orbit and pore ω, extending behind pore α onto upper cheek.
