Asperdaphne suluensis

(Original description) The solid, elongately oval shell has a short siphonal canal.

The 7 remaining whorls are convex, separated by a deep, undulated suture.

There are eighteen on the penultimate whorl and conspicuous growth lines on the ribs and the interstices.

The aperture is subquadrangularly oval, with a blunt angle above and a short, wide siphonal canal below.

The peristome is moderately thin, undulated, with a shallow sinus just below the suture, angular at the entrance of the siphonal canal.
