This species is listed as Near Threatened (close to meeting Vulnerable D2), as it is limited to a single location, and while there are not known to be any ongoing threats, any near future substantial impacts may quickly drive the species to a threatened category.

This planarian is endemic to Lake Pedder, Tasmania, Australia. Lake Pedder (originally 10 km² surface area) was formerly a natural shallow glacial lake; however, it was extensively expanded in 1972 (current surface area of 242 km²), through the damming of the Serpentine River and the Huon River for hydroelectric power generation. The species was previously listed as Extinct; however, the ongoing persistence of a population was confirmed in 2010 by Forteath and Osborn (2012). Specimens were only collected and verified along shorelines as close as possible to the original (now submerged) Lake Pedder (e.g. at Easting and Northing) (Forteath and Osborn 2012). Forteath and Osborn (2012) note that the northern shoreline was the most productive for obtaining specimens of this species. It remains unclear whether the population has dispersed, or can disperse, further around the new shoreline of Lake Pedder (Forteath and Osborn 2012). A more detailed survey is needed to define the current distribution of the species (including depth occurrence) within Lake Pedder (Forteath and Osborn 2012).

Although the species was collected in reasonable numbers at a small number of sites by Forteath and Osborn (2012) it is difficult to determine the general abundance or population trend for this species.

A detailed study into the habitat needs of this species needs to be undertaken (Forteath and Osborn 2012). It is possible that this species is limited to rocky substrata and is not present in muddy areas (Forteath and Osborn 2012), however this requires additional verification surveys.

Although the species persists at some sites in Lake Pedder, it seems possible that the overall population will have been impacted by the expansion of Lake Pedder in 1972 following the damming of the Serpentine River and the Huon River for hydroelectric power generation. Current threats to the species are less clear and require additional research, however the species remains known from only a single location and any additional threats (e.g. pollution) of Lake Pedder may impact the population.

There is no use or trade in this species.

All known subpopulations (and any potential others yet to be found around Lake Pedder) occur within Southwest National Park and is part of the Tasmanian Wilderness World Heritage Area. There is a need for additional surveys for this species more widely throughout Lake Pedder (including at different depths), to better understand the remnant distribution, and also to better understand the habitat requirements of this restricted range species (Forteath and Osborn 2012). Greater awareness of this endemic species, and other Lake Pedder endemic taxa, is potentially needed locally.
