Description

The length of the shell attains 12 mm.

The shell closely resembles Citharomangelia africana (G. B. Sowerby III, 1903), but it is smaller and with more evenly convex whorls. Furthermore, the 11 – 12 axial ribs are not arcuate below the suture. The spire is higher than in Citharomangelia richardi (Crosse, 1869). The fine spiral striae are distinct. The columella shows traces of transverse plicae. The outer lip is denticulate with 13 denticles.[2]

The whorls are narrowly round-shouldered at the top. The longitudinal plicae are close, small, rather straight. There are no revolving striae. The color is pinkish white, shining, with a subsutural interrupted chestnut band, and another about the top of the aperture. The lower half of the body whorl is pale chestnut. The interior is two-banded with chestnut. The outer lip is thickened, internally minutely crenulated.[3]

Distribution

This marine species occurs off Sri Lanka.

gollark: … ignore them and let then live their lives
gollark: You have choices. Like other jobs. Or other industries.
gollark: It's like only buying blue machines for your factory. It costs money versus not caring.
gollark: I mean, reduction of racism is... probably good for the economy... not bad as you seem to have implied.
