Type material examined TANZANIA: holotype MRAC.792352: 1 ad., Worlds View, Shume, West Usambara Mts (4.70°S, 38.20°E), in rather dry evergreen forest, leg. B. & L. Verdcourt, Dec. 1956. Other material examined None. Description SHELL (Figs 31, 59). Large (4.30 - 4.80 mm high x 1.80 x 2.50 mm wide), of 7.75 whorls. Ovate-acuminate, spire coeloconoid (spire angle 58°). Apex sharply pointed. Embryonic whorls appear smooth but with fine regular radial striae. Later whorls with relatively few, coarse ribs (about 8 per mm on penultimate whorl). Sutures of intermediate depth. Umbilicus narrowly open. Peristome incomplete parietally. Outer palatal surface of aperture with a furrow-like depression corresponding to the upper palatal tooth. Dentition 6-fold (alternatively recognisable as 5-fold), consisting of: one lamella-like parietal tooth; two palatal teeth, the upper much larger and forming a parieto-palatal sinus; one basal, in-running tooth; and a strong, squarish columellar tooth, running in to form a columellar baffle which is connected to it. Juvenile shells and anatomy unknown. Range and habitat Elevation not stated but probably between 1500-2000 m at the type locality in northeastern Tanzania. Remarks This species differs from D. minareta sp. nov. in having two palatal teeth, in having a basal tooth, in the shape of the parietal tooth, and in size.
