Fig. 7 A–B

Diagnosis

In this unusual Antipodosis gen. nov., the flattened gonostylus has a broadly rounded apex with wide pectinate tooth (↓, Fig. 7A ); the ventral parameral tusks are clearly shorter than the dorsal (↓, Fig. 7B ); and the elongate gonocoxites have practically no processes ( Fig. 7A ).

Etymology

The species epithet rotoiti is from the Maori language, meaning ‘the little lake’, with reference to Lake Rotoiti in northern South Island where this new porricondyline was collected.

TERMINALIA ( Fig. 7 A–B). Ninth tergite subtrapezoid. Gonocoxites with asetose, subtriangular portion ventroanteriorly; ventral emargination perfectly U-shaped, with narrow glabrous rim basally; medial bridges with membranous outgrowths that extend into the emargination; apices of apodemes missing, but probably merged to form a plate ( Fig. 7A ).
