背的软条 (总数) : 9; 臀鳍软条: 8; 脊椎骨: 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).
有别于 M. barbata 有达到在后鼻孔正后方的短的鼻触须; 眼放置在头部的后半段上; 第一个胸鳍鳍条短于在后部的一些, 它的顶端不形成一个明显的丝状突起; 臀鳍起源后面垂直的经过最后背鳍鳍条的基底; 每个眶上管的最后面孔在中线中联合了, 构成一个中央的孔; 额骨向前延长; 囟门不前面地延伸超过最后面的眶上孔; 蝶骨的前部具有一个突出的侧面突起; 前面的上颚成骨不存在; 上颚延长的在后部突起, 没有在后部的突起的大约 60% 的上颚多骨的部分; 而且上眼窝骨延长, 大约三倍于长达泪骨.(參考文獻 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).
出现于清澈的, 浅的溪流 (大约 60 公分深), 具有一个灰色的沙质底部, 一些标本完全地被发现的埋藏了, 除了吻与触须.(参考文献 53272)
