Armagomphus armiger is endemic to south-western Australia, where it inhabits streams and rivers.
It is a small dragonfly with black and yellow markings.
Etymology
The genus name Armagomphus is derived from the Latin arma ("arms", "armour" or "weapons of war"), combined with Gomphus, a genus name derived from the Greek γόμφος (gomphos, "peg" or "nail"), referring to the shape of the male abdomen. The name refers to the claw-like structure at the tip of the larva.
The species name armiger is Latin for "bearing arms" or "armed", referring to the spurs at the tip of the male abdomen.
