A revision of Australian Gripopterygidae (Insecta : Plecoptera)

Abstract

Twenty new species of gripopterygids are described and revised descriptions of some known species are given. Four new species are assigned to Leptoperla Newman, while four species previously in that genus plus nine new species are assigned to three new genera Newmanoperla, Cardiopevla, and Riekoperla. Newmanoperla thoreyi (Banks) from Fiji is now recorded from Australia. Leptoperla tasmanica Kimmins is determined as a junior synonym of L. beroë Newman. Three new species of genus Dinotoperla Tillyard have been described and D. thwaitesi Kimmins is declared a junior synonym of D. serricauda Kimmins. A new genus Neboissoperla is raised to contain a new species. The genus Aldia Riek is found to be a junior synonym of Trinotoperla Tillyard to which a new species is added. Three species from Trinotoperla plus two new species are assigned to the new genus Illiesoperla. Eunotoperla Tillyard is established as a genus in Gripopterygidae. A change of nomenclature for part of gripopterygid male genitalia is given. Keys to genera and species are presented where possible.
