Paracromna
''Paracromna'' is a genus of planthoppers in the family Flatidae. It was first described by Leopold Melichar Leopold Melichar (5 December 1856 – 2 September 1924) was a Moravian entomologist and physician who specialized in the taxonomy of the leafhoppers. Melichar was born in Brno, Moravia and studied medicine in Prague before beginning practice in ... in 1901. References Flatidae Auchenorrhyncha genera {{Fulgoromorpha-stub ...

Flatidae
Flatidae are a family of fulgoroid planthoppers. They are cosmopolitan in distribution and are distinguished from others in the superfamily by a combination of characters. Like all other planthoppers, they suck phloem sap of plants. Some species are known to communicate with vibrations through the plant stems. Communication may be with mates, or with ants that tend the nymphs, protecting them and gathering honeydew secretions. Adults of some species have brightly coloured forewings which are tougher and known as tegmina unlike the membranous hindwings which are used for flight. Although a few can be identified by their coloration, most species requires dissection and examination under a microscope with access to literature on already described species. There are two sub-families within the family. In the subfamily Flatinae, the body of adults is flattened laterally and the tegmina are tent-like. In the Flatoidinae, the body is not laterally compressed and the tegmina are not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leopold Melichar
Leopold Melichar (5 December 1856 – 2 September 1924) was a Moravian entomologist and physician who specialized in the taxonomy of the leafhoppers. Melichar was born in Brno, Moravia and studied medicine in Prague before beginning practice in Vienna from 1888. He became an official in the ministry of health and in his spare time he took an interest in insects. Through the influence of Ladislav Duda he began to specialize in the leafhoppers, examining the collections of Uzel Uzel (; or Uzel-près-l'Oust) is a commune in the Côtes-d'Armor department in Brittany in northwestern France. It is about west-northwest of Rennes and north-northwest of Loudéac. The old school, in the centre of Uzel, was the scene of tor ... from Sri Lanka. Melichar returned to live in Brno in 1912 and during World War I he headed the local Red Cross Hospital. Melichar also collected in North Africa, Spain and around the Mediterranean and his collections were bequeathed to the Moravian Museum. Mo ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Planthopper
A planthopper is any insect in the infraorder Fulgoromorpha, in the suborder Auchenorrhyncha, a group exceeding 12,500 described species worldwide. The name comes from their remarkable resemblance to leaves and other plants of their environment and that they often "hop" for quick transportation in a similar way to that of grasshoppers. However, planthoppers generally walk very slowly. Distributed worldwide, all members of this group are plant-feeders, though surprisingly few are considered pests. The infraorder contains only a single superfamily, Fulgoroidea. Fulgoroids are most reliably distinguished from the other Auchenorrhyncha by two features; the bifurcate ("Y"-shaped) anal vein in the forewing, and the thickened, three-segmented antennae, with a generally round or egg-shaped second segment (pedicel) that bears a fine filamentous arista. Overview Planthoppers are laterally flattened and hold their broad wings vertically, in a tent-like fashion, concealing the sides of t ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
