New and Poorly Known Gripopterygidae (Plecoptera) from Australia, especially Tasmania

Abstract

In the genus Newmanoperla the name exigua is reinstated for the Western Australian species, and a new species is described from Tasmania. The nymph of the wingless Leptoperla cacuminis from Mt Kosciusko is described. In Riekoperla a new species from Tasmania and a subspecies from King I. are described. The Tasmanian endemic Cardioperla is extensively revised, ten species with seven new specific names being recognized. In Dinotoperla a new species from both sides of Bass Strait is described, as are the unknown males of two Tasmanian species. In Trinotoperla two new species close to T. zwicki are described. For all the Tasmanian species the nymphs are comparatively described, and it is shown that in each of the genera Cardioperla, Riekoperla and Neboissoperla there is a Tasmanian species of which adults have not yet been collected.
