Chriolepis cuneata Bussing 1990

 
Papillae Drawing

IDENTIFICATION

Head Pores - No pores

Scales - Scales extend forward to below origin of second dorsal at most; posterior scales large, weakly ctenoid, becoming cycloid anterior; 14-18 in lateral series; 4 basicaudal scales outer 2 largest with elongate ctenii;

Fins - D1 - VII, anterior spines slightly longer than posterior but not elongate; D2 - 10(9-11); pectoral - 18-20; anal - 10(9-10); caudal branched rays 15(15-16), broadly lanceolate; pelvic I,5, 5th ray longer than 4th; fin reaching anus;

Head - Tongue emarginate to deeply indented, bilobed in some specimens; interorbital narrow about 1/2 eye diameter or less;

Papillae - A transverse pattern with 3 vertical rows anterior to row b.

Color - Coloration in alcohol: Background color whitish to straw-colored (occasionally appearing light brown). Body traversed by 5 or 6 (usually 5) distinct narrow light brown bands, all narrower than eye length at lateral midline, except the first (below first dorsal fin origin) which is occasionally about equal to eye length (Figs. 32 and 33). Most bands often appearing "pinched" at lateral midline, narrower ventrally and wider dorsally (frequently producing an elongated "V"-shaped band) and especially prominent as "saddles" at dorsal midline (Figs. 32 and 33). Last band (on caudal peduncle) very narrow, sometimes incompletely developed or absent. Second band (below end of second dorsal fin) often incompletely developed (onehalf to three-fourths complete) especially dorsally. Pigment of wider bands tending to concentrate at their outside edges. Posterior portion of dorsal surface of head crossed by 2 very narrow bands; the posterior, wider band above, and just anterior to, gill openings, and the anterior, narrower band (line) above, and continuing downward through, preopercular margins. Two dark brown thin bars (lines) radiating from below eye (Fig. 33); the posterior bar oblique, from posterior eye downward across upper cheek, the anterior bar vertical, from below mid-eye to posterior corner of mouth; dorsal parts of these bands represented again on interorbital as two, short, closely adjacent, parallel lines between eyes. An oblique dark bar sometimes on upper pectoral rays (Fig. 33), rest of fin clear. Pelvic fins clear. Dorsal fins and (sometimes) anal fin with continuations of body bands. A distinct, light to dark brown, wide crescentic band at base of caudal fin, its width on middle caudal rays equal to, or (usually) greater than eye length; its base usually marked by a very thin, darker portion. Rest of caudal fin unmarked. (Findley 1983)
