Elongate shell, 2.2 as high as broad. Protoconch hyperstrophic, smooth. Protoconch deeply immersed in teleoconch making protoconch 1 invisible. Teleoconch starting with two prominent and one subsutural spiral rib. Later, secondary spiral ribs appearing (eight on fifth whorl). Delicate spirallirae present between spiral ribs. Whorls angulated at the lower spiral rib. Spiral ribs crossed by weaker,slightly opisthocyrt axial ribs (about 45–47 per whorl). At intersections, blunt nodes appearing.

Porównanie

The most similar to M. striatissima but the latter differs in having unimmersed protoconch and by lacking the nodes at the intersections between the axial and the spiral ornamentation. Moreover, is also ornamented by a higher number of spiral ribs.
