Tubercliopsis quinquepilia (Laseron, 1951)

Description (based on syntypes): Shell medium size for family, broadly conical, spire straight in outline. Protoconch of about 4 whorls, (nuclear whorl broken), very tall,  smooth, with distinct junction with teleoconch. Teleoconch whorls weakly convex with suture indistinct; 3 spiral cords per whorl with interspaces about equal to width of cords. Last whorl with spiral 4 level with top of aperture, weaker than other spirals. Spirals crossed by axial ribs, forming prominent beads at intersections, moderately strong in interspaces between spirals; about 18 ribs on last whorl. Base concave, smooth. Outer lip thin. Anterior canal a deep U-shaped notch. Shell mid-brown.

Size: Figured syntype 3.4 mm in length with nuclear whorl broken.

Distribution: Syntypes from off Long Reef, Collaroy, NSW, in 26 m. No additional specimens available.

Habitat: Subtidal.

Remarks: There are three syntypes, but two have no protoconch and the protoconch of the third is broken. It is not obvious that they are all the same species.
