Sinembiidae
Sinembiidae is an extinct family of webspinners in the order Embioptera. There are at least two genera and two described species in Sinembiidae. Genera These two genera belong to the family Sinembiidae: * † '' Juraembia'' Huang & Nel, 2009 * † '' Sinembia'' Huang & Nel, 2009 Both were discovered in the Middle Jurassic of Inner Mongolia Inner Mongolia, officially the Inner Mongolia Autonomous Region, is an Autonomous regions of China, autonomous region of China. Its border includes two-thirds of the length of China's China–Mongolia border, border with the country of Mongolia. ..., and described in 2009. The female of ''Juraembia ningchengensis'' had wings, supporting Ross's proposal that both sexes of ancestral Embioptera were winged.

Embioptera
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. Webspinners are gregarious, living subsocially in galleries of fine silk which they spin from glands on their forelegs. Members of these colonies are often related females and their offspring; adult males do not feed and die soon after mating. Males of some species have wings and are able to disperse, whereas the females remain near where they were hatched. Newly mated females may vacate the colony and find a new one nearby. Others may emerge to search for a new food source to which the galleries can be extended, but in gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle Jurassic
The Middle Jurassic is the second Epoch (geology), epoch of the Jurassic Period (geology), Period. It lasted from about 174.1 to 161.5 million years ago. Fossils of land-dwelling animals, such as dinosaurs, from the Middle Jurassic are relatively rare, but geological formations containing land animal fossils include the Forest Marble Formation in England, the Kilmaluag Formation in Scotland,British Geological Survey. 2011Stratigraphic framework for the Middle Jurassic strata of Great Britain and the adjoining continental shelf: research report RR/11/06 British Geological Survey, Keyworth, Nottingham. the Calcaire de Caen of France, the Daohugou Beds in China, the Itat Formation in Russia, the Tiouraren Formation of Niger, and the Isalo III Formation of western Madagascar. Rocks of the Middle Jurassic were formerly (until about 1980s) in Europe called ''Dogger'' or ''Brown Jurassic''.

Inner Mongolia
Inner Mongolia, officially the Inner Mongolia Autonomous Region, is an Autonomous regions of China, autonomous region of China. Its border includes two-thirds of the length of China's China–Mongolia border, border with the country of Mongolia. Inner Mongolia also accounts for a small section of China's China–Russia border, border with Russia (Zabaykalsky Krai). Its capital is Hohhot; other major cities include Baotou, Chifeng, Tongliao, and Ordos City, Ordos. The autonomous region was established in 1947, incorporating the areas of the former Republic of China (1912–1949), Republic of China provinces of Suiyuan, Chahar Province, Chahar, Rehe Province, Rehe, Liaobei, and Xing'an Province, Xing'an, along with the northern parts of Gansu and Ningxia. Its area makes it the List of Chinese administrative divisions by area, third largest Chinese administrative subdivision, constituting approximately and 12% of China's total land area.
