Digoniaxis cingalensis W. H. Benson, 1863 Spiraxis cingalensis is a species of air-breathing land snails, a terrestrial pulmonate gastropod in the family Spiraxidae.

(Original description in Latin) The shell is narrowly perforate, subulate-turrite, slender, solid, polished, and finely striated, with numerous minute, closely spaced, wavy spiral striae crossing the surface.

The spire is elongated, gradually tapering above, with an undetermined apex.

The peristome is straight and calloused internally at the upper angle.

At its upper end, it is reinforced by a solid, oblique, spiral fold.
