[2] This species belongs to a genus of poorly known deep-water catsharks.

This species was first described in 2008 by Ryohei Sasahara, Keiichi Sato & Kazuhiro Nakaya.

[5] This species is known to occur in deep water (840 to 1,380 m) off New Zealand, sporadic sites around Tasmania, and a small area of Western Australia.

[2] Some concern exists for this species, as its distribution includes some heavily fished areas.

Deep-water demersal trawl fisheries are expanding in the region, and assuming its biology is like other deep-water shark species, it may not be sufficiently fecund to withstand the exploitation pressure.
