Etymology: Ancistrogobius: Name from Greek word 'agkistros' meaning fishhook and Gobius , a genus name of gobiine fish, in reference to the short, ventrally directed, spur-like preopercular spine; squamiceps: Name from the Latin words 'squama' meaning scale and 'ceps' for head, in reference to the presence of scales on head (upper part of operculum) and nape in this species.

Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 7; Mjukstrålar i ryggfenan (totalt) : 10; Taggstrålar i analfenan: 1; Mjukstrålar i analfenan: 9. This species is unique from its congeners in having the following characters: nape broadly covered by scales (12 predorsal scales); with patch of scales on upper part of operculum; in life or when fresh, filamentous part of third dorsal spine entirely pale; anterior tip of sensory papilla row b meeting row 3 anteriorly; sensory papilla rows x^1 and x^2 continuous, not interrupted by row trp (sensory papilla rows trp short, restricted under rows x^1 + x^2); third spine of first dorsal fin elongate, filamentous, distinctly longer than preceding spine; 20 pectoral-fin rays; pelvic fins fused medially, well developed connecting membrane and frenum; length of fifth segmented ray of pelvic fin 85.0-92.4% of preceding ray; a distinct, black vertical bar below eye; distal tip of first dorsal fin with a black blotch, wide, extending posteriorly to middle of third interspinal membrane; sensory papilla row 4 short, well apart from eye (always restricted below row b) (Ref. 84001).
Collected from sandy-mud or silt bottoms at depths of 20-30 m (Ref. 84001).
