Shōnen Matsumura
was a Japanese entomologist. Born in Akashi, Hyōgo, Dr. Shōnen Matsumura established Japan's first course on entomology at Hokkaido University. The courses were both applied (on insects of importance in forestry and agriculture) and theoretical. He named over 1,200 species of Japanese insects and in 1926 he founded the entomological journal ''Insecta Matsumurana.'' Matsumura wrote many scientific papers and books including ''6,000 illustrated Insects of Japan-Empire'' (1931). He died in Tokyo. His collection is in Hokkaido University in Sapporo.

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 ...

Delphacidae
Delphacidae is a family of planthoppers containing about 2000 species, distributed worldwide. Delphacids are separated from other "hoppers" by the prominent spur on the tibia of the hindleg. Diet and Pest species All species are phytophagous, many occurring on various grasses. Some species are significant pests and important vectors for cereal pathogens; for example: * The rice brown planthopper, '' Nilaparvata lugens'' (Stål) * The white-backed planthopper (rice), '' Sogatella furcifera'' (Horváth, 1899) * The sugarcane planthopper, '' Perkinsiella saccharicida'' Kirkaldy, 1903 Subfamilies, tribes and selected genera ''Fulgoromorpha Lists On the Web'' includes the following tribes and genera (complete lists where tribe unassigned): Asiracinae Auth.: Motschulsky, 1863 * Tribe Asiracini Motschulsky, 1863 * Tribe Eodelphacini Emeljanov, 1995 * Tribe Idiosystatini Emeljanov, 1995 * Tribe Neopunanini Emeljanov, 1995 * Tribe Platysystatini Emeljanov, 1995 * Tribe Tetrasteirini ...

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

Taxa Named By Shōnen Matsumura
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Auchenorrhyncha Genera
The Auchenorrhyncha suborder of the Hemiptera contains most of the familiar members of what was called the "Homoptera" – groups such as cicadas, leafhoppers, treehoppers, planthoppers, and spittlebugs. The aphids and scale insects are the other well-known "Homoptera", and they are in the suborder Sternorrhyncha. Distributed worldwide, all members of this group are plant-feeders, and many are vectors of viral and fungal diseases of plants. It is also common for Auchenorrhyncha species to produce either audible sounds or substrate vibrations as a form of communication. Such calls range from vibrations inaudible to humans, to the calls of many species of cicadas that can be heard for hundreds of metres, at least. In season, they produce the most characteristic and ubiquitous noise of the bush. Etymology The word auchenorrhyncha is from the Greek αὐχήν, 'neck, throat' and ῥύγχος, 'snout'.
