Apocordulia is a genus of dragonflies in the family Austrocorduliidae, [3] endemic to the Murray-Darling Basin in eastern Australia. [4]

Contents

Apocordulia is a monotypic genus with only one species, Apocordulia macrops, [5] [6] commonly known as a nighthawk. [4] Apocordulia macrops is a medium-sized, dull coloured dragonfly with large eyes. [4] It inhabits inland rivers [7] and flies at dawn and dusk. [8]

Etymology

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

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. [11]

This reflects current understanding of relationships within the Libelluloidea, replacing earlier treatments that placed Apocordulia variously in Corduliidae or Synthemistidae. [12]
