Information on the origin of distribution patterns shown by freshwater invertebrates in the Indo-Australian Archipelago is poor. Here we present a molecular based hypothesis of the phylogenetic relationships of Argiolestidae, a family of damselflies found throughout the tropical parts of the Eastern Hemisphere. We use this to address the following questions: (1) did Argiolestidae colonize…
Austroaeschna ingrid, a new telephlebiid from the Grampians in Victoria, Australia, is described (holotype: McKenzie Falls, 21-23 January 2008, to be deposited in Museum of Victoria, Melbourne). This species is most similar to A. Christine, A. multipunctata and A. obscura but may be distinguished by the length and slenderness of the male anal appendages, particularly…
The Australian Odonata fauna is reviewed. The state of the current taxonomy and ecology, studies on biodiversity, studies on larvae and the all identification keys are reported. The conservation status of the Australian odonates is evaluated and the endangered species identified. In addition the endemic species, species with unusual biology and species, not threatened yet,…
In this article we report underwater oviposition and epilithic oviposition in Anisoptera. We observed Notoaeschna sagittata totally submerged ovipositing on bare rock in the fast current of a rapid. Dendroaeschna conspersa oviposited also underwater, but into wood submerged in very clear water.
This paper is dedicated to Philip S. Corbet on the occasion of his 70th birthday.
The final instar of Bayadera strigata Davies & Yang, 1996, from Yunnan Province, China, is described and illustrated for the first time. This study confirms several characters as
being typical of, or unique to, the genus Bayadera and discusses them in comparison to other genera.

From their earliest appearance in the fossil record, dragonflies have clearly taken a different approach to flight than other insect groups. Even the superficially similar Neuroptera do not fly like dragonflies. Flight specialisation has enabled dragonflies to occupy a range of niches, as specialised predators of flying insects, for around 300 My.
