Genus Dignamoconcha Iredale, 1944

Pinhead Snails

 

Introduction

Dignamoconcha was originally placed in the Helicarionidae by Iredale (1944) but has subsequently been transferred to the Punctidae by Hyman & Ponder (2010) on the basis of radular and anatomical characters. The large size and acutely keeled pagoda shape make this species unique amongst the Australian Punctidae.
