Distribution of Apocordulia macrops in inland south-eastern Australia, mainly within the Murray–Darling Basin

Apocordulia macrops, commonly known as the nighthawk, is a medium-sized, dull-coloured dragonfly with large eyes. It inhabits inland rivers within the Murray–Darling Basin and is crepuscular, being most active at dawn and dusk.[7][8]

Etymology

edit

The word Apocordulia is derived from two words: apo from the Greek ἀπό meaning from or away, and Cordulia the genus of dragonfly. Tony Watson described the dragonfly genus Apocordulia as appearing different to the normal appearance of a Cordulia dragonfly.[2][9]

The species name macrops is derived from two Greek words makros (μακρός) meaning long, and ops (ὤψ) meaning eye, describing the long eye seam.[2][9]

Taxonomy

edit

In earlier higher-level classifications, the placement of Apocordulia was uncertain and it was considered incertae sedis within the superfamily Libelluloidea.[10]

A comprehensive phylogenetic revision of emerald and tigertail dragonflies by Goodman et al. (2025) reinstated the family Austrocorduliidae (stat. rev.) and showed that Apocordulia belongs within that family.[3] This replaces earlier treatments that placed Apocordulia variously in Corduliidae or Synthemistidae.[7]
