Cherax, commonly known as yabby/yabbies in Australia, is the most widespread genus of fully aquatic crayfish in the Southern Hemisphere. Various species of cherax may be found in both still and flowing bodies of freshwater across most of Australia and New Guinea. Together with Euastacus, it is also the largest crayfish genus in the Southern Hemisphere.
Casuarina 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. Plants in the genus Casuarina are monoecious or dioecious trees with green, pendulous, photosynthetic branchlets, the leaves reduced to small scales arranged in whorls around the branchlets, the male and female flowers arranged in separate spikes, the fruit a cone containing grey or yellowish-brown winged seeds.
Ensifera is a suborder of insects that includes the various types of crickets and their allies including: true crickets, camel crickets, bush crickets or katydids, grigs, weta and Cooloola monsters. This and the suborder Caelifera make up the order Orthoptera. Ensifera is believed to be a more ancient group than Caelifera, with its origins in the Carboniferous period, the split having occurred at the end of the Permian period. Unlike the Caelifera, the Ensifera contain numerous members that are partially carnivorous, feeding on other insects, as well as plants.
Rhopalosomatidae is a family of Hymenoptera containing about 68 extant species in four genera that are found worldwide. Three fossil genera are known.
Xiphydriidae are a family of wood wasps that includes around 150 species. They are located all over the world including North and South America, Australia, Europe, and others. Xiphydriidae larvae are wood borers in dead trees or branches of a range of trees. They are characterized as having long and skinny necks with dome-shaped heads. The oldest fossils of the group are from the mid Cretaceous.
Bittacidae is a family of scorpionflies commonly called hangingflies or hanging scorpionflies.
The Mymaridae, commonly known as fairyflies or fairy wasps, are a family of chalcidoid wasps found in temperate and tropical regions throughout the world. The family contains around 100 genera with 1,400 species.
Ripiphoridae is a cosmopolitan family of some 450 described species of beetles sometimes called "wedge-shaped beetles". Ripiphoridae are unusual among beetle families in that many species are hypermetamorphic parasitoids, an attribute that they share with the Meloidae. Members of the family differ in their choice of hosts, but most attack various species of bees or wasps, while some others attack cockroaches or beetles. Many species of Ripiphoridae have abbreviated elytra, and flabellate or pectinate antennae.
The Orussidae or the parasitic wood wasps represent a small family of sawflies ("Symphyta"). Currently, about 93 extant and four fossil species are known. They take a key position in phylogenetic analyses of Hymenoptera, because they form the sister taxon of the megadiverse apocritan wasps, and the common ancestor of Orussidae + Apocrita evolved parasitism for the first time in course of the evolution of the Hymenoptera. They are also the only sawflies with carnivorous larvae.
The Xyelidae are a comparatively species-poor family of sawflies, comprising about 80 extant species in five genera worldwide, and is the only family in the superfamily Xyeloidea. The fossil record of the family is extensive, comprising more than 120 species and including the oldest fossil Hymenoptera species dating back to the Triassic, between 245 and 208 million years ago. Xyelidae are to be regarded as living fossils since they represent one of the oldest lineages of insects and include still extant forms.
The Gasteruptiidae are one of the more distinctive families among the apocritan wasps, with surprisingly little variation in appearance for a group that contains around 500 species in two subfamilies and with 6 genera worldwide. They are members of Evanioidea.
Monomorium is a genus of ants in the subfamily Myrmicinae. As of 2013 it contains about 396 species. It is distributed around the world, with many species native to the Old World tropics. It is considered to be "one of the more important groups of ants," considering its widespread distribution, its diversity, and its variety of morphological and biological characteristics. It also includes several familiar pest species, such as the pharaoh ant and the flower ant.
Gryllacrididae are a family of non-jumping insects in the suborder Ensifera occurring worldwide, known commonly as leaf-rolling crickets or raspy crickets. The family historically has been broadly defined to include what are presently several other families, such as Stenopelmatidae and Rhaphidophoridae, now considered separate. As presently defined, the family contains two subfamilies: Gryllacridinae and Hyperbaeninae. They are commonly wingless and nocturnal. In the daytime, most species rest in shelters made from folded leaves sewn with silk. Some species use silk to burrow in sand, earth or wood. Raspy crickets evolved the ability to produce silk independently from other insects, but their silk has many convergent features to silkworm silk, being made of long, repetitive proteins with an extended beta-sheet structure.
Mesochorista proavita is an extinct species of scorpionfly from the Triassic period of Queensland, Australia.
Agenioideus is a genus of spider wasps from the subfamily Pompilinae; the genus occurs in Europe, where 21 species are recorded, eastwards to Japan, in North America, South America, and Australia.
Dolichogenidea is a genus of parasitoid wasps in the family Braconidae. There are more than 360 described species in Dolichogenidea, found throughout the world.
Chrysopophthorus is a genus of wasps in the family Braconidae.
Psyllaephagus is a genus of chalcid wasps. It was named and circumscribed by William Harris Ashmead in 1900. As of 2017, Psyllaephagus contains approximately 245 species.
Taeniogonalos is a genus of wasps in the family Trigonalidae.
Sathon is a genus of braconid wasps in the family Braconidae. There are more than 20 described species in Sathon, found throughout the world.
