Figs 1A , 4 A–C

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.

TERMINALIA ( Fig. 4 A–C). Ninth tergite subtrapezoid. Gonostylus elongate, slightly curved, strongly tapered towards apex ( Fig. 4A ). Gonocoxites ( Fig. 4A ) broadly rounded ventroanteriorly; processes inconspicuous, subrectangular (↓); ventral emargination evenly U-shaped, with broad glabrous rim basally; apodemes short, reaching just to ventral gonocoxal margin, slightly bilobed anteriorly.
