"Atalacmea" is a genus of true limpets, marine gastropod molluscs in the family Acmaeidae, the true limpets.

Distribution

This genus is endemic to New Zealand.

Description

"Atalacmea" shells are small, very thin, broadly elliptical, nearly flat, and with the apex near the anterior margin. The surface is smooth, except for excessively fine and dense radial lirations.

Colour patterns consist of concentric dark narrow bands.

The radula is very similar to "Notoacmea".

They are common on the undersides of smooth stones towards low water, mainly in open coast waters.
