Ammopelmatus kelsoensis, commonly known as the Kelso Jerusalem cricket, [2] is a species of insect in the family Stenopelmatidae. It is endemic to the Kelso Dunes in the United States.
Jerusalem crickets are large, striking orthopteran insects. The genus Ammopelmatus differs from other genera of stenopelmatine crickets in the following characters: [2]
Leg characters, such as the form of spines and spurs, are important for differentiating species in this genus. Ammopelmatus kelsoensis has short, spatulate apical tibial spurs and calcars. The fore tibia has only two small ventral spines, and the hind tibia has only one ventral one. Ammopelmatus muwu can be distinguished from A. kelsoensis by the curved apical spur on the internal margin of the fore tibia, the hind tibia with the first tooth on the internal margin, and first major tooth on the external margin of the hind tibia short and blunt. John and Rentz (1987) studied the chromosomes of this species. [2]
All three known specimens were collected in a burrow of a Rhachocnemis spider colony. One specimen was feeding on a small Rhacocnemis nymph. There is little known information on the life cycle, but adults were collected in mid-summer. The short, robust legs, with their reduced spines and spurs, are well-adapted for an arenicolous, or burrow-dwelling existence. [2]
The Cooloola monster is a large burrowing orthopteran of the family Cooloolidae, a family erected to accommodate it because it is so dissimilar to other ensiferans. It was discovered in 1980 in the Great Sandy National Park in Queensland, Australia, by David C. Rentz. Further members of the genus Cooloola were later discovered at other locations in Queensland.
The arthropod leg is a form of jointed appendage of arthropods, usually used for walking. Many of the terms used for arthropod leg segments are of Latin origin, and may be confused with terms for bones: coxa, trochanter, femur, tibia, tarsus, ischium, metatarsus, carpus, dactylus, patella.
Ammopelmatus cahuilaensis is a species of insect in the family Stenopelmatidae. The species is found in the Coachella Valley and was described by Ernest R. Tinkham in 1968, in The Great Basin Naturalist.
Tasmanoplectron isolatum is a rare nocturnal species of cave cricket, and is the only species represented in the genus Tasmanoplectron, belonging to the family Rhaphidophoridae. In 1971, Aola M. Richards was first to describe this species in Tasmania, Australia, where its geographical distribution is restricted to. The genus is thought to have affinities with New Zealand fauna due to its marked differences from the other Australian Rhaphidophoridae.
Sphecomyrma is an extinct genus of ants which existed in the Cretaceous approximately 79 to 92 million years ago. The first specimens were collected in 1966, found embedded in amber which had been exposed in the cliffs of Cliffwood, New Jersey, by Edmund Frey and his wife. In 1967, zoologists E. O. Wilson, Frank Carpenter and William L. Brown, Jr. published a paper describing and naming Sphecomyrma freyi. They described an ant with a mosaic of features—a mix of characteristics from modern ants and aculeate wasps. It possessed a metapleural gland, a feature unique to ants. Furthermore, it was wingless and had a petiole which was ant-like in form. The mandibles were short and wasp-like with only two teeth, the gaster was constricted, and the middle and hind legs had double tibial spurs. The antennae were, in form, midway between the wasps and ants, having a short first segment but a long flexible funiculus. Two additional species, S. canadensis and S. mesaki, were described in 1985 and 2005, respectively.
Callopistria rivularis is a species of moth of the family Noctuidae. It is found from the Indo-Australian tropics of India, Sri Lanka up to the Solomon islands and Fiji.
Araneagryllus is an extinct monotypic genus of cricket in the subfamily Phalangopsinae with the sole species Araneagryllus dylani. The fossil was recovered in the Dominican Republic from early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola. Araneagryllus is the first Phalangopsinae cricket to be described from the fossil record.
Agdistopis sinhala is a moth of the family Macropiratidae. It is found in south-east Asia, including Sri Lanka, India, Japan and Taiwan.
Coxoplectoptera or "chimera wings" is an extinct order of stem-group mayflies containing one family, Mickoleitiidae.
Cebrionini is a tribe of click beetles from the family Elateridae; formerly ranked as a subfamily or family, they are now considered a tribe within the subfamily Elaterinae.
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.
Zigrasimecia is an extinct genus of ants which existed in the Cretaceous period approximately 98 million years ago. The first specimens were collected from Burmese amber in Kachin State, 100 kilometres (62 mi) west of Myitkyina town in Myanmar. In 2013, palaeoentomologists Phillip Barden and David Grimaldi published a paper describing and naming Zigrasimecia tonsora. They described a dealate female with unusual features, notably the highly specialized mandibles. Other features include large ocelli, short scapes, 12 antennomeres, small eyes, and a clypeal margin that has a row of peg-like denticles. The genus Zigrasimecia was originally incertae sedis within Formicidae until a second species, Zigrasimecia ferox, was described in 2014, leading to its placement in the subfamily Sphecomyrminae. Later, it was considered to belong to the distinct subfamily Zigrasimeciinae.
Haidomyrmex is an extinct genus of ants in the formicid subfamily Haidomyrmecinae, and is one of nine genera placed in the subfamily Haidomyrmecinae. The genus contains three described species Haidomyrmex cerberus, Haidomyrmex scimitarus, and Haidomyrmex zigrasi. All three are known from single Late Cretaceous fossils which have been found in Asia. H. cerberus is the type species and Haidomyrmex the type genus for the subfamily Haidomyrmecinae.
Pristomyrmex tsujii is a species of ant in the genus Pristomyrmex. Known from Fiji, where they are widely distributed but rarely encountered. The species has a discrete ergatoid queen caste that is intermediate between a worker and an alate queen.
Eucteniza is a genus of trapdoor spiders in the family Euctenizidae containing at least 14 species occurring in Mexico and the southern United States. Species are distinguished by a softened rear portion of the carapace, and males possess large spines on the first two pairs of walking legs that are used to hold females during mating. Like other trapdoor spiders they create burrows with a hinged lid, from which they await passing insects and other arthropods to prey upon. Many species are known from only one or two localities, or from only male specimens. More species are expected to be discovered. Eucteniza is closely related to spiders of the genera Entychides and Neoapachella.
Holotrichia reynaudi is a species of dung beetle found in South India and Sri Lanka.
Haaniella gintingi is a stick insect species from Sumatra. It is a typical representative of the subfamily Heteropteryginae. The occasionally used common name Ginting’s Haaniella refers to the species name.
Acanthogryllus fortipes, or the brown cricket, is a species of cricket from southern Africa. It is mostly dark brown in colour and has a large head. It is a common species in short grass, including artificial habitats such as lawns and fields.
Perothops is a genus of false click beetles in the family Eucnemidae containing 3 species. They are known as beech-tree beetles or perothopid beetles. It is the only genus in the monotypic subfamily Perothopinae. They are small, dark-colored beetles that are found across the United States, generally in forests.
