Scythris Bifissella
''Scythris'' is a genus of gelechioid moths. It is the type genus of the flower moth family, which is sometimes included as a subfamily in the ''Xyloryctidae'', or together with these merged into the Oecophoridae. The genus was erected by Jacob Hübner in 1825. It is the largest genus of flower moths, and as such might not be fully monophyletic with regard to some very small or monotypic genera placed in the same family. In addition, new species of ''Scythris'' continue to be discovered and described.FE (2009), and see references in Savela (2008) Selected species Species groups The species of ''Scythris'' have been divided among several groups, which may or may not be monophyletic; those that are may – provided they are closely enough related to the type species '' S. limbella'' – be considered subgenera. There is a considerable number of species whose exact relationships are hitherto elusive. Some have been placed in a "monospecific species group" of their own, a ...

Imago
In biology, the imago (Latin for "image") is the last stage an insect attains during its metamorphosis, its process of growth and development; it is also called the ''imaginal'' stage ("imaginal" being "imago" in adjective form), the stage in which the insect attains maturity. It follows the final ecdysis of the immature instars. In a member of the Ametabola or Hemimetabola, species in which metamorphosis is "incomplete", the final ecdysis follows the last immature or '' nymphal'' stage. In members of the Holometabola, in which there is a pupal stage, the final ecdysis follows emergence from the pupa A pupa (; : pupae) is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages th ..., after which the metamorphosis is complete, although there is a prolonged period of maturation in some species. The imago is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological Type (biology), type wiktionary:en:specimen, specimen (or specimens). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the International Code of Nomenclature for algae, fungi, and plants, code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name with that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have suc ...
