Pharsalus (planthopper)
''Pharsalus repandus'' is a species of planthopper insects described by Leopold Melichar in 1906.Melichar L (1906) ''Monographie der Issiden. (Homoptera). Abhandlungen der K. K. Zoologisch-botanischen Gesellschaft in Wien.'' Wien 3: 1–327 [221]. It is the monotypic taxon, sole member of ''Pharsalus'', the type genus of the subfamily Pharsalinae of the family Ricaniidae.

Leopold Melichar
Leopold Melichar (5 December 1856 – 2 September 1924) was a Moravian entomologist and physician who specialized in the taxonomy of the Cicadellidae, 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 Jindřich Uzel, Uzel 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. Most of the taxa described by Melichar were based on external morphology and did not involve examination of the genitalia.

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 few are considered pests. Fulgoromorphs 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 the body and part of the legs. Nymphs of many planthoppers produce wax from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of Genus, genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical o ...

Type Genus
In biological taxonomy, the type genus (''genus typica'') is the genus which defines a biological family and the root of the family name. Zoological nomenclature According to the International Code of Zoological Nomenclature, "The name-bearing type of a nominal family-group taxon is a nominal genus called the 'type genus'; the family-group name is based upon that of the type genus." Any family-group name must have a type genus (and any genus-group name must have a type species, but any species-group name may, but need not, have one or more type specimens). The type genus for a family-group name is also the genus that provided the stem to which was added the ending -idae (for families). :Example: The family name Formicidae has as its type genus the genus ''Formica'' Linnaeus, 1758. Botanical nomenclature In botanical nomenclature, the phrase "type genus" is used, unofficially, as a term of convenience. In the '' ICN'' this phrase has no status. The code uses type specimens ...

Ricaniidae
Ricaniidae is a family (biology), family of planthopper insects, containing over 400 species worldwide. The highest diversity is in tropical Africa and Asia and in Australia, with a few species occurring in the Palearctic and Neotropical realms. It is one of the smaller families in the planthopper Taxonomic rank, superfamily Fulgoroidea. Subfamilies and genera As of 2022, ''Fulgoromorpha Lists on the Web'' includes: Subfamily Pharsalinae (Neotropical - all presently monotypic) * ''Pharsalus (planthopper), Pharsalus'' * ''Ricamela'' * ''Silvanana'' Subfamily Ricaniinae * ''Acroprivesa'' * ''Alisca'' * ''Aliscella'' * ''Apachnas'' * ''Aprivesa'' * ''Armacia'' * ''Armilustrium (planthopper), Armilustrium'' * ''Carmentalia (planthopper), Carmentalia'' * ''Coniunctivena'' * ''Cotrades'' * ''Cyamosa'' * ''Deferundata'' * ''Deraulax'' * ''Epitemna'' * ''Epithalamium (planthopper), Epithalamium'' * ''Euricania'' * ''Globularica'' * ''Hajar (planthopper), Hajar'' * ' ...
