The Lake Pedder Earthworm is only known by the type specimen collected from a beach on Lake Pedder, Tasmania in 1971. In 1972, the area was inundated for hydroelectric power generation. A survey in 1996 was carried out to determine the conservation and taxonomic status of Lake Pedder earthworms and to determine whether H. pedderensis still existed in the area. Directed sampling of the area leading to the original collection site failed to find the species. Several new species were found, however, none are conspecific to H. pedderensis and the species is likely to be extinct due to inundation of its original and unique habitat.
