Description (holotype) (Fig. 14 A–C). Shell small, fusiform, with high elevated spire (LWL/SL 0.51) and attenuated short canal. Shell consisting of nearly two protoconch whorls and 6.25 convex, angulated, teleoconch whorls. Protoconch (Fig. 14 F, paratype) paucispiral, globose, sculptured with microscopic spiral threads, diameter 930 Μm, height 890 Μm, transition to teleoconch weakly demarcated by onset of two spiral cords. Suture impressed. Besides inconspicuous, strongly sinuous, growth lines with deep broad anal sinus on whorl periphery, axial sculpture consisting of narrow, closely spaced, ribs matching the growth lines in shape, 12 on penultimate whorl, 13 on last whorl. Axial ribs running from suture to suture on spire whorls, although rather low above shoulder, and becoming obsolete on shell base at transition to canal; on first teleoconch whorl, 10 narrow, closely spaced, weakly sinuous, and slightly prosocline, axial ribs; on second whorl, axial ribs and anal sinus becoming progressively deeper, reaching the adult profile by last half of second whorl. Spiral sculpture consisting of a narrow subsutural cord, appearing on second whorl and progressively shifting abapically, ...
