Range Description

This species was originally only known from the St. Paul and Amsterdam Islands in the southern Indian Ocean, with a single specimen has also been reported from the Kerguelen Islands (Holthuis 1991), however recently additional specimens have been collected from seamounts along the South West Indian ridge (J. Groeneveld pers. comm. 2011). These indicate that the species is far more widely, but sparsely, distributed along the South West Indian ridge than previously thought.
