Lauxaniidae
The Lauxaniidae are a family of acalyptrate flies. They generally are small flies (length 7 mm or less) with large compound eyes that often are brightly coloured in life, sometimes with characteristic horizontal stripes, such as in '' Cestrotus'' species. Many species have variegated patterns on their wings, but in contrast they generally do not have variegated bodies, except for genera such as ''Cestrotus'', whose camouflage mimics lichens or the texture of granitic rocks. Some 1800 species of Lauxaniidae have been described and they comprise some 126 genera. The family has a cosmopolitan distribution, most of the species occurring in tropical regions of Asia and the Americas; relatively few species occur in Afrotropical regions, and Lauxaniid species diversity declines strongly towards the more temperate regions; for example fewer than 200 European species have been described. Most species inhabit forests, where the adults usually are found sitting on leaves of the under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Costa Rica
Costa Rica (, ; ; literally "Rich Coast"), officially the Republic of Costa Rica ( es, República de Costa Rica), is a country in the Central American region of North America, bordered by Nicaragua to the north, the Caribbean Sea to the northeast, Panama to the southeast, the Pacific Ocean to the southwest, and Maritime boundary, maritime border with Ecuador to the south of Cocos Island.

Lauxanioidea Genera
The Lauxanioidea are a superfamily of flies that includes the two large families, the Lauxaniidae and Chamaemyiidae, and the small family Celyphidae. Generally, they are small to medium, densely populated, coloured flies. The Chamaemyiidae live as parasites on insects. The family Celyphidae look like beetles. Some authors also recognize the family Cremifaniidae, but most place this in the Chamaemyiidae. Description The superfamily has three synapomorphies (features present in all members due to a common ancestor): convergent postocellar bristles, an abbreviated anal vein in the wing, and fusion of male abdominal tergites 7 and 8. Within the superfamily, Celyphidae can be distinguished from other families by their scutellum, which is shiny, enlarged and covers most of the abdomen, similar to a beetle's elytra. Lauxaniidae are yellowish-brown or black, usually have iridescent reddish/purplish or greenish eyes, and the wings are sometimes patterned. Chamaemyiidae are usually sil ...
