Comparative morphology of the male Australian Nepidae (Hemiptera : Heteroptera)

Abstract

The male genitalia and wing venation of Austronepa, Laccotrephes, and Ranatra are described and compared. A general description is given of the male of Austronepa angusta (Hale). It is concluded that the male genitalia do not seem to provide reliable subfamily or tribal characters in the genera studied.
