Cicadidae
Cicadidae, the true cicadas, is the largest family of cicadas, with more than 3,200 species worldwide. The oldest known definitive fossils are from the Paleocene, a nymph from the Cretaceous Burmese amber has been attributed to the family, but could also belong to the Tettigarctidae. Description Cicadas are large insects characterized by their membranous wings, triangular-formation of three ocelli on the top of their heads, and their short, bristle-like antennae. Life cycle Cicadas are generally separated into two categories based on their adult emergence pattern. Annual cicadas remain underground as nymphs for two or more years and the population is not locally synchronized in its development, so that some adults mature each year or in most years. Periodical cicadas also have multiple-year life cycles but emerge in synchrony or near synchrony in any one location and are absent as adults in the intervening years. The most well-known periodical cicadas, genus ''Magicicada'', e ... [...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 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. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...
