Dorsale zachte stralen (totaal) : 9; Anale zachte stralen: 8; Wervels: 34. Differs from M. barbata in having short nasal barbels reaching just behind posterior nostril; eye positioned on posterior half of head; first pectoral-fin ray shorter than posterior ones, its tip not forming a distinct filament; anal fin origin posterior of vertical through base of last dorsal-fin ray; posteriormost pore of each supraorbital canal united in the midline, composing a single median pore; frontal elongated anteriorly; fontanel not extending anteriorly beyond posteriormost supraorbital pore; anterior portion of sphenotic with a prominent lateral process; anterior palatine ossification absent; posterior process of palatine elongate, about 60% of palatine bony portion without posterior process; and supraorbital bone elongate, about three times as long as lacrimal (Ref. 53272).
Occurs in clear, shallow streams (about 60 cm deep), with a gray sandy bottom, where some specimens were found entirely buried, except for snout and barbels (Ref. 53272).
