Diagnosis

A combination of genitalic characters is specific to A. pureora gen. et sp. nov., as follows ( Fig. 5 A–B). Of the gonocoxites ( Fig. 5A ), the processes are small and subtriangular (↓), the large ventral emargination is perfectly U-shaped (↓), and the apodemes are merged into a large plate with rounded margins (↓). The base of the ejaculatory apodeme is strongly widened (↓, Fig. 5B ), which is unique in Antipodosis gen. nov.

Differential diagnosis

Antipodosis pureora gen. et sp. nov. is similar to both A. australis gen. et sp. nov. and A. rotoroa gen. et sp. nov. The three species differ from each other in the ejaculatory apodeme, which is strongly widened basally in A. pureora gen. et sp. nov. ( Fig. 5B ), markedly widened subapically in A. australis gen. et sp. nov. ( Fig. 2B ), and two-pointed apically in A. rotoroa gen. et sp. nov. ( Fig. 8B ). Other interspecific distinctions are described under each of the species.

Etymology

The name pureora is from the Maori language, referring to Pureora Forest, one of the largest intact tracts of native podocarp forest in the North Island and collection site of this species.
