The Pentatomoidea are a superfamily of insects in the suborder Heteroptera of the order Hemiptera. As hemipterans, they possess a common arrangement of sucking mouthparts. The roughly 7000 species under Pentatomoidea are divided into 21 families. Among these are the stink bugs and shield bugs, jewel bugs, giant shield bugs, and burrower bugs.

<span class="mw-page-title-main">Psyllid</span> Family of true bugs

Psyllidae, the jumping plant lice or psyllids, are a family of small plant-feeding insects that tend to be very host-specific, i.e. each plant-louse species only feeds on one plant species (monophagous) or feeds on a few closely related plants (oligophagous). Together with aphids, phylloxerans, scale insects and whiteflies, they form the group called Sternorrhyncha, which is considered to be the most "primitive" group within the true bugs (Hemiptera). They have traditionally been considered a single family, Psyllidae, but recent classifications divide the group into a total of seven families; the present restricted definition still includes more than 70 genera in the Psyllidae. Psyllid fossils have been found from the Early Permian before the flowering plants evolved. The explosive diversification of the flowering plants in the Cretaceous was paralleled by a massive diversification of associated insects, and many of the morphological and metabolic characters that the flowering plants exhibit may have evolved as defenses against herbivorous insects.

<i>Casuarina</i> Genus of trees

Casuarina, also known as she-oak, Australian pine and native pine, is a genus of flowering plants in the family Casuarinaceae, and is native to Australia, the Indian subcontinent, Southeast Asia, islands of the western Pacific Ocean, and eastern Africa.

<span class="mw-page-title-main">Psylloidea</span> Superfamily of true bugs

Psylloidea is a superfamily of true bugs, including the jumping plant lice and others which have recently been classified as distinct families. Though the group first appeared during the Early Jurassic, modern members of the group do not appear until the Eocene, and Mesozoic members of the order are usually assigned to the possibly paraphyletic family Liadopsyllidae.

<span class="mw-page-title-main">Triozidae</span> Family of true bugs

Triozidae is one of seven families collectively referred to as jumping plant lice. They have traditionally been considered part of a single family, Psyllidae, but recent classifications divide the group into a total of seven families; most of the genera remain in the Psyllidae, but Triozidae is the third-largest family in the group, containing 27 genera, and a number of pest species.

Aacanthocnema burckhardti is a species of jumping plant lice, first found as a sap-sucker 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 lacks hinaria on its eighth antennal segment as well as sclerotised spurs on its hind tibia. Females of the species lack a posterior apical hook on their proctiger.

Punia is a genus of cicadas in the family Cicadidae endemic to Australia. Members of the genus are called grass pygmies. There are currently five described species in Punia. They are found in Western Australia, the Northern Territory and Queensland. The genus was considered to be a monotypic genus only containing P. minima until the 2020 description of four congeners.
