A pale, very slender darter with 4 or 5 dark crossbars that extend obliquely forward from the back onto the sides. The back and upper sides are pale yellow; the underparts are silvery-white. Midside with a series of oblong dusky blotches. Fins lack definite markings.
The upper lip is not separated from the snout by a deep groove; instead, it is joined at the midline by a narrow bridge of skin (the frenum). The body is fully scaled except for the breast and belly. Lateral line complete. Tail fin deeply forked.
