Épines dorsales (Total) : 6; Rayons mous dorsaux (Total) : 15 - 16; Épines anales: 1; Rayons mous anaux: 15. This species differs from its congeners by the following characters: terminal mouth oblique; absence of a large blotch on pectoral-fin base; trunk with a large blotch anterodorsally beneath pectoral fin and a series of small midlateral spots, but no series of large midlateral blotches with vertical extensions; D2 and A each with 15 elements; broadly confluent dorsal fins; small cycloid scales completely covering trunk and nape, with 70 or more in a lateral series; upper jaw with one complete row of teeth in most specimens, but 2 or 3 appearing in larger individuals; first gill arch with 8 thin rakers on ceratobranchial, 6 on epibranchial (Ref. 55435).
Collected from tidepools, over sand and mud bottoms (Ref. 55435).
