Acanthocasuarina tasmanica

Acanthocasuarina tasmanica is a species of jumping plant louse, first found on plants of the genus Allocasuarina in Australia. The species is characterised by exhibiting an elongate habitus; short Rs and short cubital forewing cells; ventral genal processes beneath the apical margin of its vertex; short antennae; and nymphs that are elongate and very sclerotised (scale-like). It possesses rhinaria on its fourth, sixth, eighth and ninth antennal segments; the species' hind tibia has one outer and two inner spurs, while the female's proctiger carries an apical hook posteriorly.
