Campellolebias chrysolineatus

description

Description 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 3 rd or 4 th anal-fin rays in male, reaching between base of 1 st and 3 rd 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 2 nd and 3 rd dorsal-fin rays in males, between base of 3 rd and 4 th dorsal-fin rays in females. Dorsal-fin o

diagnosis

Diagnosis Similar to C. brucei and distinguished from C. dorsimaculatus 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 4 th anal-fin ray in males (vs. reaching anterior base of pseudogonopodium). Distinguished from C. brucei 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).
