A new species of Amoria J. E. Gray, 1855 from Ashmore Reefs

This paper presents a new species of Amoria from the Ashmore Reefs, Western Australia, a species which has been long been confused by collectors with Amoria spenceriana (Glatiff, 1908) of the Ashmore Banks, off Far North Queensland. Amoria textilata n. sp. shows differences in morphological characteristics and geographic separation from similar species of the Amoria complex. A. textilata can be differentiated from all other members of its genus by its angulated shoulders, the presence of only three columella plaits instead of the usual 4 found in most Amoria species, and a fine tent-like patterning across the shell. Amoria textilata is found intertidally down to an estimated depth of 15-20 m.
