Other genitalic structures distinctive of this species are the gonostylus, which is swollen on the basal two thirds and flattened on the apical third (↓, Fig. 6A ), and the gonocoxites, which have prominent, rectangular processes (↓). Etymology The species epithet rakiura is identical with the Maori name commonly used for Stewart Island where this species was found.
