Differential diagnosis.

This species is similar to H. bubalus sp. nov. with which it is also geographically approximate. It differs from it by a clearly narrower umbilicus. Hypselostoma bubalus sp. nov. is also spirally striated on some isolated parts of the shell (above or below the keel), but H. luctans is not. See also under H. piconis.

Distribution.

This species is known from Peninsular Malaysia and Yala Province in Thailand.

Remarks.

There can be two interpalatal plicae, and in some cases, none are visible. Umbilicus can sometimes be slightly wider, with a stronger groove inside (than the figured specimen).
