Cyprinella zanema
Unique Characters: Long conical barbel in corner of mouth. Dorsal-fin origin modally 2.5 scales (range: 1.5–3) posterior to pelvic-fin origin. Dark crosshatching on back and sides. Slender, compressed body. Restricted to the Catawba and Broad River basins.
Similar Species:
All species of Cyprinella have dark pigment on the last 2-4 interradial membranes of the dorsal fin, but only Santee Chub, Siouan Thinlip Chub, and Thicklip Chub possess maxillary barbels.
Thicklip Chub
Cyprinella labrosa
Thicklip Chub Cyprinella labrosa. Darker cross-hatching on back and sides. Small brown blotches on the sides. Compressed thicker body, flattened below. Dorsal fin origin over pelvic origin. Usually pigment in posterior part of dorsal fin.
Siouan Thinlip Chub
Cyprinella leptocheilus
Siouan Thinlip Chub Cyprinella leptocheilus. Very similar in appearance to Santee Chub. Siouan Thinlip Chub is distinguished from Santee Chub by having: 1) dorsal-fin origin (position) modally 1.5 scales posterior to the pelvic-fin origin; vs. dorsal-fin origin modally 2.5 scales posterior to the pelvic-fin origin; 2) mean upper lip width at midpoint 2.1% of head length vs. mean upper lip width at midpoint 3.5% of head length; 3) mean upper lip width at midline 2.9% of head length vs. mean upper lip width at midline 4.1% of head length; and mean maxillary barbel length 3.5% of head length vs. mean maxillary barbel length 8.0% of head length.
Siouan Thinlip Chub is endemic to Sand Hills and upper Coastal Plain streams of the Lumber, Cape Fear, and Yadkin River basins.
