Hemilienardia albostrigata explained

Hemilienardia albostrigata is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae.^[1]

Description

The length of the shell varies between 3 mm and 8 mm.

The shell is whitish or light yellowish brown, marked on the back of the body whorl with a pure white chalky-looking band, and in some instances with an interrupted band of brown.^[2]

This is a pure-white turreted little species, with a conspicuous dorsal squarrose brown spot just below the suture of the body whorl. The whorls are ventricose and ribbed longitudinally, crossed with a few conspicuous lirae. The outer lip is much thickened with large denticles on the inner surface, and the columella is toothed.^[3]

It differs from Hemilienardia apiculata (Montrouzier in Souverbie & Montrouzier, 1864) by the presence of a brown spot on the edge of the body whorl.^[4]

Distribution

This marine species occurs off New Caledonia and Queensland, Australia
