Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 81 - 93; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 62 - 71. This species differs from other members of the genus by having dark spots along the upper and lower edges of its body, extending to basal part of the dorsal and anal fins, posterior part of the caudal fin and a dark band, upper limb of gill arch with gill rakers. This genus is characterized by having eyes separated by a bony ridge of very narrow space anteriorly and a ridge posteriorly, a small mouth about equal to eye diameter, ctenoid scales on ocular side armed with a row of hairlike spines.
Body shape (shape guide): short and / or deep; Cross section: compressed.
Inhabits sand and mud bottoms (Ref. 9824). Feeds on small polychaetes, crustaceans, and fishes (Ref. 9824). Caught mainly with bottom shrimp trawls (Ref. 9824).
