New protomyrmeleontid damselflies from the Triassic of Australia and the Liassic of Luxembourg, with the description of Tillyardomyrmeleon petermilleri gen. nov. & spec. nov. (Archizygoptera: Protomyrmeleontidae)

Tillyardomyrmeleon petermilleri gen. n. & sp. n., the oldest known Protomyrmeleontidae is described from the Mid Triassic of Australia. A new Protomyrmeleontidae probably related to the genus Zirzipanagrion Zessin, 1991, is described from the Liassic of Luxembourg. An attempt of a phylogenetic analysis of the genera of Protomyrmeleontidae is proposed. A newly discovered well-preserved wing of a Liassic Protomyrmeleontidae shows that the primary antenodal crossveins of Archizygoptera are homologous to those of recent Odonata.
