This species was originally described from the Ross Sea, Antarctica, and the name has been used as a "catch-all" for members of this genus from the Australian-New Zealand-Antarctic region. It is highly likely that records of this species from Australia and New Zealand actually refer to as-yet unrecognised distinct species in the genus.
