Diagnosis |
Distinguished from all congeners by having the following combination of characters: a circular humeral spot that does not pass ventrally below the lateral-line canal and has a only a diffuse, inconspicuous vertical extension; short scales with a rounded posterior margin at the base of the caudal-fin; melanophores present on the posterior margins of the scales all along the sides of body; a dark lateral stripe, formed by deep pigment that is continuous with the caudal peduncle spot; wide, concave pelvic bone; middle part of the dorsal margin of the orbito-sphenoid bone concave, and not in contact with the frontal; ventral tip of extrascapular bifurcate; first postcleithrum not contacting cleithrum; the portion of maxilla with teeth does not reach the dorsal border of the dentary; all maxillary teeth tricuspid; caudal peduncle spot continuous with the dark lateral stripe; and humeral spot extending on to the posterior part of the opercle (Ref. 95113). Description: Dorsal-fin rays ii-iii,7-8; anal-fin rays iii-v,21-25; pectoral-fin rays ii-iii,8-12 ; pelvic-fin rays i-ii,5-7 (Ref. 95113). |
