Sinembiidae is an extinct family of webspinners in the order Embioptera. There are at least two genera and two described species in Sinembiidae. [1] [2] [3]
These two genera belong to the family Sinembiidae:
Both were discovered in the Middle Jurassic of Inner Mongolia, and described in 2009. The female of Juraembia ningchengensis had wings, supporting Ross's proposal that both sexes of ancestral Embioptera were winged. [4]
The Trachypachidae are a family of beetles that generally resemble small ground beetles, but that are distinguished by the large coxae of their rearmost legs. There are only six known extant species in the family, with four species of Trachypachus found in northern Eurasia and northern North America, and two species of Systolosoma in Chile and Argentina. They were much more diverse in the past, with dozens of described species from the Mesozoic.
The order Embioptera, commonly known as webspinners or footspinners, are a small group of mostly tropical and subtropical insects, classified under the subclass Pterygota. The order has also been called Embiodea or Embiidina. More than 400 species in 11 families have been described, the oldest known fossils of the group being from the mid-Jurassic. Species are very similar in appearance, having long, flexible bodies, short legs, and only males having wings.
Bittacidae is a family of scorpionflies commonly called hangingflies or hanging scorpionflies.
The Tettigarctidae, known as the hairy cicadas, are a small relict family of primitive cicadas. Along with more than 20 extinct genera, Tettigarctidae contains a single extant genus, Tettigarcta, with two extant species, one from southern Australia and one from the island of Tasmania. Numerous fossil species have been described from the Late Triassic onwards. Tettigarcta are the closest living relatives of the true cicadas.
Archaeidae, also known as assassin spiders and pelican spiders, is a spider family with about ninety described species in five genera. It contains small spiders, ranging from 2 to 8 millimetres long, that prey exclusively on other spiders. They are unusual in that they have "necks", ranging from long and slender to short and thick. The name "pelican spider" refers to these elongated jaws and necks used to catch their prey. Living species of Archaeidae occur in South Africa, Madagascar and Australia, with the sister family Mecysmaucheniidae occurring in southern South America and New Zealand.
Anisembiidae is a family of insects in the order Embioptera, the web-spinners. The family is divided into several subfamilies. It is the largest family of webspinners.
Rhopalidae, or scentless plant bugs, are a family of true bugs. In older literature, the family is sometimes called "Corizidae". They differ from the related coreids in lacking well-developed scent glands. They are usually light-colored and smaller than the coreids. Some are very similar to the orsilline lygaeids, but can be distinguished by the numerous veins in the membrane of the hemelytra. They live principally on weeds, but a few are arboreal. All are plant feeders. The type genus for the family is: Rhopalus. Currently 30 genera and over 240 species of rhopalids are known. The oldest fossil rhopalids described are from the Middle Jurassic of Inner Mongolia, discovered from the Haifanggou Formation. They are not considered economically important with a few species being pests of ornamental trees.
Mesokristensenia is an extinct genus of moth in the family Mesokristenseniidae. It existed in what is now China during the middle Jurassic period. It was named by Huang Diying, André Nel and Joël Minet in 2010, and the type species is Mesokristensenia latipenna.
Mongolbittacus is an extinct genus of hangingfly in the family Bittacidae and containing a single species Mongolbittacus daohugoensis. The species is known only from the Middle Jurassic Jiulongshan Formation, part of the Daohugou Beds, near the village of Daohugou in Ningcheng County, northeastern China.
Mesoraphidiidae is an extinct family of snakeflies in the suborder Raphidiomorpha. The family lived from the Late Jurassic through the Late Cretaceous and is known from twenty-five genera. Mesoraphidiids have been found as both compression fossils and as inclusions in amber. The family was first proposed in 1925 by the Russian paleoentomologist Andrey Vasilyevich Martynov based on Upper Jurassic fossils recovered in Kazakhstan. The family was expanded in 2002 by the synonymizing of several other proposed snakefly families. The family was divided into three subfamilies and one tribe in a 2011 paper, further clarifying the relationships of the included genera.
The Stenophlebiidae is an extinct family of medium-sized to large fossil odonates from the Upper Jurassic and Cretaceous period that belongs to the damsel-dragonfly grade ("anisozygopteres") within the stem group of Anisoptera. They are characterized by their long and slender wings, and the transverse shape of the discoidal triangles in their wing venation.
Dascillidae is a family of beetles within the clade Elateriformia. There are about 100 extant species in 11 genera, which are found worldwide. Dascillidae together with Rhipiceridae form the super family Dascilloidea.
Oligotomidae is a family of webspinners in the order Embioptera. There are about 6 genera and at least 40 described species in Oligotomidae.
Andesembiidae is a family of webspinners--insects of the order Embioptera. There are at least two genera and about seven described species in Andesembiidae.
Archembiidae is a family of webspinners in the order Embioptera. There are at least 2 genera and about 12 described species in Archembiidae.
Australembiidae is a family of webspinners in the order Embioptera. There is at least one genus, Metoligotoma, in the family Australembiidae.
Clothodidae is a family of webspinners in the order Embioptera. There are about 8 genera and 25 described species in Clothodidae.
Embiidae is a family of webspinners in the order Embioptera. There are more than 20 genera and 80 described species in Embiidae.
Paedembiidae is a family of webspinners in the order Embioptera. There are at least three genera and three described species in Paedembiidae.
Scelembiidae is a family of webspinners in the order Embioptera. There are about 16 genera and more than 40 described species in Scelembiidae.
