Platygryllus is a genus of crickets in the subfamily Gryllinae. [1] [2] Records of species distribution (probably incomplete) include Africa, southern Europe and in Asia: India, Java and the Philippines.
Males of this genus transfer sperm to the female via a spermatophore which is externally attached to a females ovipositor. Male P. supplicans guard females after spermatophore transfer to prevent the female from removing his spermatophore prematurely. [3] The females of P. primiformis use premature spermatophore removal as a form of cryptic female choice leaving larger males' spermatophores attached for significantly longer than smaller males.

The Orthoptera Species File includes:
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.
Gryllinae, or field crickets, are a subfamily of insects in the order Orthoptera and the family Gryllidae.
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.
Tree crickets are insects of the order Orthoptera. These crickets are in the subfamily Oecanthinae of the family Gryllidae.
Trigonidiinae is a subfamily of insects in the order Orthoptera, suborder Ensifera, based on the type genus Trigonidium. They are often referred to as sword-tail crickets, winged bush crickets or trigs.
Gryllus is a genus of field cricket. Members of the genus are typically 15–31 mm long and darkly coloured. The type species is Gryllus campestris L.: the European field cricket.
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.
Teleogryllus is a genus of crickets in the family Gryllidae. Species can be found in Africa, Asia, Australia and the Pacific islands.
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.
Nemobiinae is a subfamily of the newly constituted Trigonidiidae, one of the cricket families. The type genus is Nemobius, which includes the wood cricket, but members of this subfamily may also be known as ground crickets or "pygmy field crickets".
Gymnogryllus is a genus of crickets in family Gryllidae and tribe Gryllini. Species are recorded from Africa, Asia and Australia.
Tafalisca is a genus of silent bush crickets in the family Gryllidae. Records for described species in Tafalisca are mostly from Central and South America.
Podoscirtinae is a subfamily of crickets in the family Gryllidae.
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.
Modicogryllini is a tribe of crickets of the family Gryllidae. Species are terrestrial, carnivorous or omnivorous and can be found in all continenents except Antarctica.
Gryllini is a tribe of crickets and typical of the family Gryllidae. Species are terrestrial, carnivorous or omnivorous and can be found in all continenents except Antarctica.
Velarifictorus is a genus of crickets in the family Gryllidae and tribe Gryllini. Species have been recorded in Australia, Asia, Africa and the southeastern US.
Phonarellus is a genus of crickets in the family Gryllidae and tribe Gryllini. Species can be found in mainland Asia, Japan and tropical Africa.
Modicogryllus is the type genus of crickets in the tribe Modicogryllini. Species have been recorded from: Europe, Africa, the middle East, temperate and tropical Asia through to Australia and western Pacific islands.
