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; yanoi: Named for K.Yano, who provided several type specimens and habitat information for all the new species of Ancistrogobius.
Eponymy: Korechika Yano is a diving instructor and underwater photographer at the Dive Service YANO, Iriomote Island, Japan. [...] (Ref. 128868), visit book page.

Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 7; членистые (мягкие) лучи спинного плавника (общее число) : 10; колючие лучи анального плавника: 1; членистые (мягкие) лучи анального плавника: 9. This species differs from its congeners in having the following set of characters: no scales on head and most of nape (no predorsal scales); third spine of first dorsal fin elongate and filamentous, obviously longer than preceding spine (at least in specimens that are more than 21 mm SL), with alternating pale and dusky pattern in life or when fresh (typically faded and indistinct in preserved specimens, but its distal tip tinged with black); 17-19 (usually 18 or 19) pectoral-fin rays 1; pelvic fins fused medially by well developed connecting membrane and frenum (frenum often rudimentary); fifth segmented ray of pelvic fin 89.9-100.0% of preceding ray in length; faint, dusky blotches below eye (not forming a distinct vertical bar); distal tip of first dorsal fin with a black blotch, relatively wide, extending posteriorly to just behind third spine (but not to middle of third interspinal membrane); sensory papilla rows x^1 and x^2 not continuous (interrupted by row trp); sensory papilla rows trp extending dorsally to slightly above a longitudinal line through rows x^1 + x^2; anterior tip of sensory papilla row b closed to, or attaching with, row 4 and well apart from row 3; row d typically extending posteriorly to well beyond ventral end of row 6i (Ref. 84001).
Body shape (shape guide): elongated; Cross section: oval.
Collected from sandy-mud bottoms at depths of 0-12 m (Ref. 84001).
