Diagnosis

Antipodosis granvillensis gen. et sp. nov. is distinguished from the congeneric species by two unique characters: the gonostylus bears apically a single, tooth-like spine (↓, Fig. 4A), and the dorsal parameral tusks are two-branched (↓, Fig. 4B).

Etymology

The name granvillensis, an adjective, is derived from Granville State Forest in the West Coast region of South Island, which is the type locality of this species.
