Hadopyrgus rawhiti is a critically endangered species of freshwater snail native to New Zealand.

Contents

Habitat

This snail has been found in only one location: [3] a seepage by a waterfall in a stream between Hopewell & Raetihi, behind Double Bay, Kenepuru Sound. [4] The population trend of this snail is currently unknown, but it is considered potentially threatened by habitat destruction. [3]

Conservation status

In November 2018 the Department of Conservation classified Hadopyrgus rawhiti as Nationally Critical under the New Zealand Threat Classification System. [1] The species was judged as meeting the criteria for Nationally Critical threat status as a result of it only being found in one location which was less than 1 ha in size. [1]
