Introduction
Following Davies & Tobin (1984) the Australian and Papuan genus Diphlebia Selys was included by Houston & Watson (1988) in the Amphipterygidae. Novelo-Gutierrez (1995) on the basis of larvae proposed a new classification with Diphlebia assigned with Lestoidea Tillyard and Philoganga Kirby to the family Diphlebiidae and Amphipteryx Selys, Devadatta Kirby, Pentaphlebia Förster and Rimanella Needham to the Amphipterygidae. The priority of Lestoideidae over Diphlebiidae was demonstrated by Van Tol (1995) and subsequently accepted by Theischinger (1996). However, an alternative view of Bechly (1996) considers that Lestoidea belong in Hypolestidae, and Diphlebiidae thus becomes the name of the group containing Diphlebia once again (see Hawking & Theischinger 1999). Watson (1966) discussed the structure and function of the gill tufts in larval Amphipterygidae, while Stewart (1980) revised Diphlebia and no undescribed species are known. Hawking & Theischinger (1999) give an illustrated key to the larvae of New South Wales species.
Diagnosis
Adult: accessory antenodal crossveins present, primary antenodals evident; postnodal crossveins not necessarily aligned with crossveins behind them; discoidal cell entire or (in some non-Australian genera) traversed by crossveins; IR3 and R4 originating close to arculus; wings (in Australian species) held open at rest.
Larva: labium flat, broad, lacking major setae, palps narrow, median lobe cleft; gills saccoid, with tapered tips; anal laminae in Australian species not modified into gill tufts (cf. Watson, 1966).
