Description of Material
Shell of average for the genus, adult size up to 2.8 mm; fusifom, elongate. Slightly shouldered whorls. Suture slightly impressed. Protoconch paucispiral, consisting of about 1.4-1.5 whorls and with a clear carina. Transition to teleoconch clearly visible. Teleoconch consisting of about 3.8whorls. Axial sculpture clearly present on all whorls, consisting of close set axial ribs with narrow interspaces. There are 17 of these ribs on the first whorl, increasing to 24 on the last whorl. Last axial ribs close to the aperture much stronger. Spiral sculpture absent, apart from the basal cords, which ventrally range to about the adapical end of the columella. Most adapical basal cords and axial ribs forming knobs on the intersections. Aperture typical for the genus: narrow and rather elongate, about 43% of shell height. Outside of outer lip thickened, with the continuation of the basal cords on the abapical end. Inside of outer lip with a weak sinus on the adapical end and very weak almost obsolete denticles. Columellar callus rather weak, not raised, with a thickened part at about the middle. Parietal callus weak. Siphonal canal short, open, slightly recurved. First teleoconch whorl starting pinkish, further on the teleoconch this fades fast to a more salmon color. Columella and aperture white. Protoconch pink. Height of holotype: 2.8 mm
Ecology
Direct developing species with paucispiral protoconch, so non planctotrophic larvae. Most likely endemic.
