Biology Type of larval development: direct (non planktotrophic) denoted by paucispiral protoconch. [details]

Diagnosis Shell 2.0 to 2.4 mm high, with protoconch of a little more than 1.25 whorls and teleoconch of 3.25 to 3.5 whorls. Protoconch smooth, teleoconch with very poorly defined axial folds. Body whorl rounded with 4-5 well marked spiral cords abapically.
Teleoconch with characteristic “Porosalvania” microsculpture consisting of minute (ca. 1 µm) pits randomly distributed, visible only under high magnification of scanning electron microscope. Outer lip thickened externally at a short distance from the edge by a faint rim, then thinning out to a cutting edge; smooth inside. Shell colourless, translucent.

This species most resembles P. semisculpta, Gofas, 2007 from which it differs in having a still more slender, more translucent shell and in lacking the strong, definite axial folds. [details]

Distribution Plato seamount, endemic, moderately common at 710 m. [details]

Type locality Plato seamount (33º11.8'N, 28º57.0'W, 710 m). [details]
