Diagnosis

A combination of genitalic characters is characteristic of G. tewaipounamu sp. nov., as follows. The elongate, slightly bent gonostylus has a densely microtrichose bulge dorsobasally (↓ 1, Fig. 16B ). Of the gonocoxites, the posteromedial protuberance is largely unmodified except for inconspicuous folds, which indicate some kind of structuring (↓ 2, Fig. 16A ); and the medial bridges have a section with large, dense microtrichia (↓ 3, Fig. 16A ). The posterolateral processes of the tegmen, which are strongly sclerotized, are a complicated assemblage of teeth, tubercles and serrate ridges (↓ 4, Fig. 16C ).

Etymology

The name of this species, tewaipounamu , is the original Maori name for the South Island of New Zealand, where the holotype was collected.
