This undescribed endemic belongs to a genus of poorly known deepwater catsharks and is recorded from only three specimens taken off Perth, Western Australia. This species could be rare or uncommon, and the effects of fisheries are unknown, though if its biology is like other deepwater shark species, it may not be sufficiently fecund to withstand exploitation pressure.
