Diagnosis (amended from Starnes & Starnes 1978) 



A Phoxinus with one single wide black lateral stripe (two stripes in young) extending from 

 anterior of nasal opening to the caudal fin base; no connection between the left and right 

 stripes at anterior of snout; intestine elongate with six loops in adults; opercle elongated 

 and narrow; epibranchials 2 and 4 bearing an elongate posterior process; epibranchial 5 

 with a deep broad concavity on its posterior margin; pharyngeal bone with a notch at its 

 posterior limb; anterior process of basioccipital elongate: often displaying a head-down 

 swimming attitude (Starnes & Starnes 1978). 



Description (Tab. 6) 



A North American species of Phoxinus reaching about 60 mm standard length. Head short, 

 its length 25% of standard length, its width 51% of its length. Snout short and blunt, its 

 length 17% of head length. 1017c of orbit length. Eye lateral on head, moderately large; 

 orbit length 29% of the head length. Mouth small and slightly oblique; its gape not ex- 

 tending to below anterior margin of eye. Lower jaw shorter than upper one, and included 

 by the latter. 



Bony interorbital space wide, its length 101% of orbit length, and 32% of head length. 

 In young individuals (SL <23.5 mm), axis of olfactory organ semi-round and located in 

 anterior portion of organ, four primary lamellae placed around posterior margin of axis. 

 In adults, axis elongate and located mesially extending from anterior to posterior parts of 

 organ; ten primary lamellae present along lateral and mesial margin of axis. Melanopho- 

 res present on primary lamellae and axis in most specimens. 



Body moderately deep and slightly compressed. Maximum body depth 25% of standard 

 length. Caudal peduncle high and relatively short, its depth 35% of its length. 

 Pectoral fin with 13-18 rays, 15 rays in most specimens. Pectoral fin round, its distal tip 

 close to origin of pelvic fin in male: pectoral fin sharper, shorter, and not approaching to 

 origin of the base of the pelvic fin in females. Pelvic fin with 7-9 rays, eight rays in most
