簡単な記述
形態学 | 形態計測学
背面の脊椎 (合計): 7; 背鰭 (合計): 10; 肛門の骨 1; 臀鰭: 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).
Collected from sandy-mud bottoms at depths of 0-12 m (Ref. 84001).
