Key to subtribes and genera of Zolini ( New Zealand)

Remarks. The only character distinguishing the genera Oopterus and Zolus is the shape of the right paramere of the aedeagus. To separate Zolus species from Oopterus species using external morphology, see the Key to species of Oopterus where Zolus species are inserted and cross-referenced to the Zolus key.
