Opacuincola dulcinella is a critically endangered species of fresh water snail native to New Zealand.[1]

Habitat

This snail has been found in two caves in very close proximity within a 1 km² area in Pohara, Takaka . The population trend of this snail is unknown at present but it is regarded as potentially threatened by urban development and groundwater removal and contamination.[3]

Conservation Status

In 2013 the Department of Conservation classified Opacuincola dulcinella as Nationally Critical under the New Zealand Threat Classification System. The species was judged as meeting the criteria for Nationally Critical threat status as a result of it occupying a total area of less than 1 hectare. It is found only in what is regarded as one location and is also classified as Data Poor under the threat classification system.[1]
