Punctum sp. ‘Agakauitai’

Agakauitai Dot Snail (Punctum sp.)  

This form is up to now only known from a single specimen, which comes from the island of Agakauitai, and which was very probably not more closely examined yet. [1]  

It may, however, possibly be identical with the Mokoto Dot Snail (Punctum mokotoense Abdou & Bouchet).
