Diagnostic Features: Snout broadly rounded-angular in dorsoventral view, rather short and broad; anterior nasal flaps subtriangular, not overlapping mouth posteriorly. Claspers short and stout. Colour pattern variegated, with up to 11 dark brown irregular saddles and laterally interdigitating blotches in a checkerboard pattern in the typical New Zealand form, but with more irregular dark blotches and mottling in Taiwanese and Japanese representatives of the species (if not distinct); a scattering of numerous dark brown or blackish' small spots on a grey or brown background; underside of head and abdomen unspotted; fins without conspicuous light margins.
