Habitat edit
This snail has been found in two caves in very close proximity within a 1 km2 area in Pōhara, near Tākaka. 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 edit
In November 2018 the Department of Conservation classified Opacuincola dulcinella 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 occupying a total area of less than 1 hectare. It is found in what is regarded as one location and is also classified as Data Poor under the threat classification system.[1]
