Diagnosis. Shell dextral, elongate-conical fusiform, dull to translucent, whitish to yellowish. Whorls ~ 7–8, well rounded; spire elongate-conical; suture wide, deep. Teleoconch with equally spaced, weak to strong radial ribs throughout. Penultimate whorl wider than preceding and last whorls. Aperture rounded; columellaris strong, distinct, directed downward. Peristome expanded, double; lip thickened, multi-layered. Umbilicus closed. Distribution. The species is currently known only from its type locality, ‘ Mya Leit Douang, Ava’, which likely refers to the Myaleit Mountains in the Mandalay Region, Myanmar.
