Otoconcha dimidiata

Otoconcha dimidiata is a species of small air-breathing semi-slug, a terrestrial pulmonate gastropod mollusc in the family Charopidae.

It has a very thin and cap like shell hidden under its skin in the rounded swelling behind the head.

This species occurs in both North and South islands of New Zealand.

It can be found by careful searching by torch light in damp areas of native forest.

Otoconcha dimidiata is the preferred prey of the carnivorous land gastropod Schizoglossa novoseelandica.
