Revised description. Shell small, very slender turreted of at least nine teleoconch whorls (apical angle ~13°). Protoconch unknown. Early teleoconch whorls strongly convex with broad, weakly convex subsutural ramp. Prominent, moderately widely spaced, weakly prosocline axial ribs. Spiral sculpture of prominent, broad subsutural cord, seven prominent, strongly convex cords below and one weaker cord at abapical suture. Later whorls becoming allometrically higher and less convex, with broad, steep, weakly convex and poorly delimited subsutural ramp, faint angulation, periphery just below mid-whorl. Suture deeply impressed, linear. Sculpture of prominent, widely spaced, weakly prosocline axial ribs (~10: ~10: ~11), separated by wider interspaces, overrun by up to eight broad, strap-like spiral cords, separated by narrower groove-like interspaces, forming low, rounded nodes at intersections. Basal angulation delimited by prominent peribasal cord. Base weakly concave with four prominent spiral cords. Aperture ovate. Outer lip thin, weakly convex. Columellar and parietal callus indistinct. Peristome simple. No umbilicus.

Discussion. Papuliscala subsoluta (Boettger, 1907) differs from all its Paratethyan congeners in having broad, strap-like spiral cords separated by narrow grooves, so that the sculpture is not cancellate as seen in most species. The basal cords are also stronger than in any other Paratethyan Papuliscala species. It was erroneously placed in the Triphoridae genus Metaxia Monterosato, 1884 by Boettger (1907) and subsequent authors but the prominent axial ribs exclude a relation with Triphoridae .

Paleoenvironment. Unknown. Extant Papuliscala species are found in deep water environments ( Bouchet & Warén, 1986).
