Archiperlaria, eine neue Unterordnung der Plecopteren (Revision der Familien Eustheniidae und Diamphipnoidae) (Plecoptera).

Abstract

A revision of the family Eustheniidae Tilly. (Plecoptera) is given. The former subfamily Diamphipnoinae Ricker is transformed to the rank of a family and also revised. The various, mostly archaic characters common to both families (such as lateral abdominal gills in the larvae - see fig. 6 and 12 -, plesiomorph genital system - see fig. 2 — and numerous crossveins in the anal part of hind wings in the adults - see fig. 5 and 14) allow to establish a new suborder: Archiperlaria. The range of distribution of the Eustheniidae shows (fig. 4.) that the group is endemic in the southern hemisphere and that its evolution took place in a former antartic continent, connecting New Zealand + Australia with the southern parts of western South America. As new genera and species are described (Eustheniidae): Neuroperlopsis patris n. gen. n. sp. (fig. 9, 10), (Diamphipnoidae): Diamphipnoa helgae n. sp.(fig. 1, 15), Diamphipnopsis samali n. gen. n. nom. (fig. 12a, 13a, 18, 19), Diamphipnopsis beschi n. sp. (fig. 20).
