Caudal peduncle depth 26.9-33.1% of its length (Ref. 91771).Description: Body long-oval shape (Ref. 91771). Head broadly rounded with a small ventrally positioned subterminal mouth, situated ventral to the eye; head and body dorsolaterally compressed (Ref. 91771). Dorsal fin origin situated about two-thirds of standard length from snout, obliquely orientated, anteriorly higher and posteriorly lower, distal margin crescentic with anterior two or three rays longer than posterior rays, and number of rays 22-25. Anal fin longer than dorsal fin, opposite dorsal fin with slightly more anterior origin, obliquely orientated, anteriorly lower and posteriorly higher, anterior 10 or so rays longer than posterior ones, especially in males where they also appear stronger, margin broadly rounded, rays posterior to first 10 with distal margin straight, number of rays 30-35 (Ref. 91771). Scales cycloid with reticulate striae, scales extending anteriorly to operculum and pectoral fins; scales in lateral series 39-42; scales on caudal peduncle circumference, 11-12 (Ref. 91771). Caudal peduncle slender, subcylindrical entire length, between 18.4-19.9% of standard length (Ref. 91771).Colour: In preservation: Body brown, back only slightly darker, breast and belly fair, fins rather unpigmented and transparent, anal and dorsal fin bases emphasized as dark lines (Ref. 91771). A well-circumscribed dark spot below dorsal fin origin, except for some specimens (Ref. 91771). Kramer, B., R. Bills, P. Skelton and M.
