Similar to C. brucei  ZBK  and distinguished from C. dorsimaculatus  ZBK  and C. intermedius  by having dorsal and anal fins long in males, tip reaching posterior half of caudal fin (vs. reaching basal portion of caudal fin) and pelvic-fin tip reaching base of 4th anal-fin ray in males (vs. reaching anterior base of pseudogonopodium). Distinguished from C. brucei  ZBK  in possessing 2 + 10-12 supraorbital neuromasts (vs. 3 + 13-16), sides of body purplish pink, with 7 horizontal golden lines in males (vs. dark purplish red with 7 horizontal rows of metallic green spots), pale orange stripes on flank in females (vs. no pale orange stripe), and black spots just below lateral midline on anterocentral portion of flank in females (vs. no black spot, sometimes small black dots).


Morphometric data given in Table 1. Males larger than females, largest male 38.1 mm SL, largest female 32.3 mm SL. Dorsal profile convex from snout to end of dorsal-fin base, approximately straight on caudal peduncle. Ventral profile gently convex from lower jaw to end of anal-fin base, nearly straight on caudal peduncle. Body moderately slender, slightly compressed. Greatest body depth at level of pelvic-fin base.

Dorsal and anal fins pointed and elongate in males, terminating in short filament reaching vertical through posterior half of caudal fin; dorsal and anal fins rounded, short and without filamentous rays in females. Caudal fin rounded. Pectoral fins elliptical. Posterior margin of pectoral fins reaching vertical between pelvic-fin base and anus. Tip of pelvic fins reaching base of 3rd or 4th anal-fin rays in male, reaching between base of 1st and 3rd anal-fins ray in females. Pelvic-fin bases medially separated by interspace about half pelvic-fin base width. Dorsal-fin origin anterior to anal-fin origin, anal-fin origin on vertical between base of 2nd and 3rd dorsal-fin rays in males, between base of 3rd and 4th dorsal-fin rays in females. Dorsal-fin origin between neural spines of vertebrae 10 and 11. Anal-fin origin between pleural ribs of vertebrae 11 and 12. Dorsal-fin rays 15-18; analfin rays 2 + 14-15 in males, 15-17 in females; caudal-fin rays 27-29; pectoral-fin rays 14-15; pelvic-fin rays 6.

Scales large, cycloid. Body and head entirely scaled, except on anteroventral surface of head. Dorsal and anal-fin bases without scales. Scales covering anterior 10 % of caudal fin. Frontal squamation E-patterned, E-scales not overlapping. Longitudinal series of scales 27; transverse series of scales 7; scale rows around caudal peduncle 12. Three to seven minute contact organs on exposed margin of each scale of ventral portion of flank in male. Minute papillate contact organs on internal surface of distal portion of pectoral-fin rays 1-4 in males.

Cephalic neuromasts: supraorbital 2 + 10-12, parietal 1, anterior rostral 1-2, posterior rostral 1-2, infraorbital 3 + 25-26, preorbital 3, otic 2, post-otic 2, supratemporal 1, median opercular 1-2, ventral opercular 1-3, preopercular 19-21, mandibular 9-10, lateral mandibular 3-4, paramandibular 1. Three to seven neuromasts on each scale of lateral series. Transverse row of neuromasts on caudal-fin base 5-7.

Basihyal triangular, longest width about 40 % of length; basihyal cartilage about 35 % of total length of basihyal. Six branchiostegal rays. Second pharyngobranchial absent. Gill-rakers on first branchial arch 2-3 + 9-10. Vomerine teeth absent. Dermosphenotic absent. Ventral process of posttemporal absent. Total vertebrae 29.


Males: Sides of body purplish pink, with 7 horizontal golden lines. Sides of head dark purplish pink, scales of opercular region golden. Iris bright yellowish green, with dark reddish brown bar through center of eye. Dorsum light brown. Venter white to bluish white; dark reddish gray stripe along ventrolateral region of head; dark brown midventral stripe from lower jaw to pseudogonopodium. Dorsal and anal fins light pink, with small reddish brown spots on basal and posterior portions, dark gray with blue to golden iridescence on distal and anterior portions; narrow golden marginal line along anterior edge of fins. Caudal fin light pink, with small reddish brown spots, and narrow golden marginal line. Pelvic fins dark bluish gray, sometimes with narrow golden line on anterior margin. Pectoral fins hyaline.

Females: Sides of body light brownish gray, with 6 gray horizontal lines alternating with pale orange stripes; black spots on anterocentral portion of flank just below lateral midline, sometimes coalesced to form short black stripes; small black spots on posterior portion of caudal peduncle. Venter white to pale golden. Opercular region greenish golden. Iris light yellow, with brown bar through center of eye. Unpaired fins hyaline, with small black spots on basal region, larger on caudal-fin base. Paired fins hyaline.
