Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 27 - 28; Anal spines: 0; Anal soft rays: 26; Vertebrae: 19. Maximum known size small (3.6 cm SL); soft Doral rays 27-28; anal rays 26; pectoral rays 11/11; dorsal profile of snout straight in male, slightly concave in female, without prominent hump just before nostrils; soft dorsal and anal fins not elevated anteriorly, outer margins convex; soft dorsal fin of male with second ray elongate and filamentous; caudal fin moderately long (about equal to head length), posterior margin convex; pelvis capable of moving vertically through an arc of about 40 degrees, producing a moderately large ventral flap; lobe on rear of pelvis small, directed dorsoposteriorly; pelvic fin rudiment relatively short and small, posterior segment movably articulated with pelvis; midbody scales each with up to six minute spinules located on a transverse ridge, those on caudal peduncle of male slightly longer, recurved, forming a poorly defined patch of bristles (Ref. 48594).
Body shape (shape guide): short and / or deep.
