Chriolepis sp. nov. s Findley In Prep.

 

IDENTIFICATION

Head Pores - No head or preopercle pores

Scales - body almost completely scaled; posterior scales largest and ctenoid, becoming cycloid anteriorly, scales extend anteriorly to 4th D1 spine than start to slope down to pectoral fin base; 24-29 in lateral series; 4 basicaudal scales

 

Fins - D1 - VII, no elongate spines; D2 - 10(10-11); pectoral 16(15-17); anal 10(9-10);

Head - maxilla extending to below middle of eye; interorbital narrow about equal to pupil diameter; anterior nostril a long narrow tube; posterior nostril wider and lower than anterior;

Papillae - A transverse pattern

Color - preserved color: background color of head and body light brown to yellowish, with small specks. Sexual dichrmatism in color pattern remarkable. Females: Body crossed by six or seven distinct more or less regular, dusky bands; width of each about equal to eye length. Edges of bands often sinuous, especially posteriorly and along lateral midline. Pigment of bands concentrated at outer edges, producing appearance of many, very thin, dark bands on body which extend onto dorsal fins. Edges of narrow band on caudal peduncle often joining near lateral midline to produce a sinuous "y-shaped" thin band. Caudal fin with 7-9 distinct, very thin, dark bands, similar to edges of body bands, those nearest base of fin crescentic. Rear portion of dorsal surface of head transversed by two bands similar to those on body, the anterior one above opercula and narrower, the posterior and wider one across nape, bisected by pectoral fin bases. A thin dark vertical line at preopercular margin, continuing upward to dorsal surface of head where it is usually broken at dorsal midline. Three distinct narrow bands radiating from eye, one obliquely upward from posterior eye, one obliquely downward from posterior eye, and one ventrally from mid-eye; the latter two perhaps representing the dark edges of a very faint, diverging, wide band below eye. An extremely faint oblique line on snout from anterior eye to upper jaw may be indicated. Pectoral and pelvic fins clear. A thin longitudinal dark band usually present at edge of anal fin. Male: coloration drab, lacking all bands and other color pattern as described for female, except the thin band at edge of anal fin. (Findley 1983)
