Etymology
The genus name Austrogomphus is derived from two words: the Latin word auster meaning south wind, hence south; and the Greek word gomphus (γόμφος) meaning peg or nail. It is suggested that the shape of the male tail is generally like that of a bolt used in ship building. Gomphus is also a genus of dragonfly, with some similarities to Austrogomphus, both belonging to the much larger family group, Gomphidae. In 1854 Edmond de Sélys Longchamps named the sub-genus Austrogomphus probably as a southern or Australian component of the gomphid group.
