Locustavidae is an extinct family of grasshoppers in the order Orthoptera. There are about 6 genera and 12 described species in Locustavidae, with fossils found in Australia, China, Kyrgyzstan, and Russia. [1] [2] [3]
These six genera belong to the family Locustavidae:
The orthopteran family Rhaphidophoridae of the suborder Ensifera has a worldwide distribution. Common names for these insects include cave wētā, cave crickets, camelback crickets, camel crickets, Hogan bugs, spider crickets and sand treaders. Those occurring in New Zealand, Australia, and Tasmania are typically referred to as jumping or cave wētā. Most are found in forest environments or within caves, animal burrows, cellars, under stones, or in wood or similar environments. All species are flightless and nocturnal, usually with long antennae and legs. More than 500 species of Rhaphidophoridae are described.
The family Gryllidae contains the subfamilies and genera which entomologists now term true crickets. Having long, whip-like antennae, they belong to the Orthopteran suborder Ensifera, which has been greatly reduced in the last 100 years : taxa such as the spider-crickets and allies, sword-tail crickets, wood or ground crickets and scaly crickets have been elevated to family level. The type genus is Gryllus and the first use of the family name "Gryllidae" was by Walker.
The family Prophalangopsidae are insects belonging to the order Orthoptera. They are the only extant members of the superfamily Hagloidea. There is only one extant genus in North America, where they are known as grigs, four genera in Asia, and many extinct genera.
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.
The family Stenopelmatidae is composed of large, mostly flightless insects resembling crickets. Two genera: Ammopelmatus and the type genus Stenopelmatus are found in the New World. Oryctopus and Sia are Old World genera, and previously placed in their own subfamilies, but with the addition of new genera, current placement is as five tribes in the single subfamily Stenopelmatinae.
Tetrigidae is an ancient family in the order Orthoptera, which also includes similar families such as crickets, grasshoppers, and their allies. Species within the Tetrigidae are variously called groundhoppers, pygmy grasshoppers, pygmy devils or "grouse locusts".
Phalangopsinae, occasionally known as spider crickets, are a subfamily of crickets in the family Phalangopsidae. Members of Phalangopsinae are found worldwide in tropical and subtropical regions. Most species in the subfamily are nocturnal and can be found in rocky areas, near fallen wood, and the understory of forests. Some species are gregarious, gathering in large numbers.

The Tridactylidae are a family in the insect order Orthoptera. They are small, mole-cricket-like insects, almost always less than 20 mm (0.79 in) long when mature. Generally they are shiny, dark or black, sometimes variegated or sandy-coloured. They commonly live in short tunnels and are commonly known as pygmy mole crickets, though they are not closely related to the true "mole crickets" (Ensifera), as they are included in the Caelifera suborder.
The Eneopterinae are a subfamily of crickets, in the family Gryllidae, based on the type genus Eneoptera. It is one of several groups widely described as "true crickets". Of the more than 500 species that make up this subfamily, most occur in moist, tropical habitats. These insects are medium to large and brown or gray in color. They eat plant leaves, flowers, and fruits and can occasionally cause economic damage. Their eggs are deposited in pith, bark, or wood. Eneopterinae show a great diversity in stridulatory apparatus, signals emitted, and associated behaviour.
The cohort Polyneoptera is a proposed taxonomic ranking for the Orthoptera and all other Neopteran insects believed to be more closely related to Orthoptera than to any other insect orders. These winged insects, now in the Paraneoptera, were formerly grouped as the Hemimetabola or Exopterygota on the grounds that they have no metamorphosis, the wings gradually developing externally throughout the nymphal stages.
Tettigoniidea is an infraorder of the order Orthoptera, with six extant families.
The Phalangopsidae are a recently reconstituted family of crickets, based on the type genus PhalangopsisServille, 1831 from South America. Priority for family-group names based on this genus dates from Blanchard's "Phalangopsites".
The Landrevinae are a subfamily of crickets, in the family Gryllidae, based on the type genus Landreva. They are terrestrial, omnivorous and may be known as "bark crickets"; genera are distributed in: Central and South America, Africa, tropical Asia, Korea, Japan, Australia and the Pacific Islands.
Baissogryllidae is an extinct family of crickets in the order Orthoptera. There are about 20 genera and 30 described species in Baissogryllidae.
Locustopsidae is an extinct family of grasshoppers in the order Orthoptera. There are about 17 genera and more than 60 described species in Locustopsidae.
Protogryllidae is an extinct family of crickets in the order Orthoptera. There are about 8 genera and more than 20 described species in Protogryllidae.
Regiatidae is an extinct family of grasshoppers in the order Orthoptera. There are at least three genera and four described species in Regiatidae.
Tettoedischiidae is an extinct family of Orthoptera. There are at least two genera and two described species in Tettoedischiidae.
Thueringoedischiidae is an extinct family of long-horned Orthoptera. There are at least three genera and three described species in Thueringoedischiidae.
Elcanidae are an extinct family of Mesozoic and early Cenozoic orthopterans. Members of the family are distinguished by the presence of spurs on the distal part of the metatibia, unique among orthopterans, these have been suggested to have been used for controlling gliding, swimming aids, or for jumping on water. The group combines characteristics from both major groups of orthopterans, with long antennae and nymphal morphology similar to Ensifera, but with wing venation and adult morphology more similar to Caelifera. Their closest relatives are the extinct family Permelcanidae, known from the Early-Late Permian, with which they form the superfamily Elcanoidea, whose relationship to Ensifera and Caelifera are unresolved. Elcanids are known from the Late Triassic to Paleocene of Eurasia, North and South America. Some members of the group exhibited aposematic coloration.
