Description

The shell forms an almost straight sided cone and the whorls are nearly flat. The colour is light yellowish to brownish, the surface being rather shiny and a little transparent. The embryonic whorls are characterized by d = 130 µm and D = 250 µm ( see fig. 7). The top is rather blunt. The breadth of the shell is just over sixty percent of the total length, the last whorl occupies about seventy percent and the mouth is a bit less than fifty percent of the total length. The mouth is holostome without interruption on the body-whorl and the growthlines are strongly prosocline. The average dimensions are around three mm. at about four whorls, not counting the embryonic ones. Holotype: 3.1 x 2.0 mm. Type-locality: Sfax, Tunisia.
Etymology. - This species is named after prof. dr. E. Gittenberger, well-known malacologist and friend, at the occasion of his retirement from active duty at Naturalis as well as at the Leiden University.

Interchangeable taxa

This species differs from the well-known Assiminea grayana by the more blunt protoconch and its bigger embryonic whorls with dimensions of d = 130 µm and D = 250 µm ( see fig. 7). The dimensions of the shells are smaller and the radula of the animal differs too, according to Cesari.
