Morphology | Morphometrics
soft rays: 10. Scales in lateral series 52-59; cheek scaled; opercle scaled; pectoral base scaled; breast scaled; belly anteriorly scaled next to pelvic base; predorsal midline usually with naked patches, seldom fully scaled; four blackish crescentic bars between second dorsal and anal fins, and two blackish crescentic bars below first dorsal fin, these markings extend to ventral surface (Ref. 34009).
Known from lowland rivers and streams primarily over mud bottoms in fresh water.
