Prosorrhyncha
The name Prosorrhyncha is a name (proposed by Sorensen et al. 1995) for a suborder of Hemiptera, comprising a grouping of the traditional taxon "Heteroptera" plus its sister taxon, the family Peloridiidae (often classified as a suborder itself). There is no agreement on the status of this taxon, as there are two competing classifications regarding this branch of the Hemiptera; while some hemipterists follow this classification (link below), it has by no means been accepted universally. See the Heteroptera article for the detailed discussion, and a comparison of the two taxoboxes. Note that there is a "conflict within the conflict" regarding the use of the name "Prosorrhyncha", as it is not the oldest name suggested for this particular group of taxa; the name "Heteropteroidea" (Schlee 1969) is older, as is "Heteropterodea" (Zrzavy 1992). However, as the Code of Nomenclature does not regulate taxon names above the rank of family, there is no actual rule that the oldest name must be ...

Heteroptera
The Heteroptera are a group of about 40,000 species of insects in the order Hemiptera. They are sometimes called "true bugs", though that name more commonly refers to the Hemiptera as a whole. "Typical bugs" might be used as a more unequivocal alternative, since the heteropterans are most consistently and universally termed "bugs" among the Hemiptera. "Heteroptera" is Greek for "different wings": most species have forewings with both membranous and hardened portions (called hemelytra); members of the primitive sub-group Enicocephalomorpha have completely membranous wings. The name "Heteroptera" is used in two very different ways in modern classifications. In Linnean nomenclature, it commonly appears as a suborder within the order Hemiptera, where it can be paraphyletic or monophyletic depending on its delimitation. In phylogenetic nomenclature, it is used as an unranked clade within the Prosorrhyncha clade, which in turn is in the Hemiptera clade. This results from the realiza ...

Peloridiidae
The Peloridiidae or moss bugs are a family of true bugs, comprising eighteen genera and thirty-four species. They are small, ranging in length from 2 to 4 mm, rarely seen, peculiarly lumpy, flattened bugs found in Patagonia (Argentina and Chile), New Zealand, eastern Australia, Lord Howe Island, and New Caledonia. Peloridiids are found amongst mosses and liverworts, commonly in association with southern beech forests. They have become known as moss bugs for their habit of feeding on mosses. Almost all Peloridiidae species are flightless, except one (''Peloridium hammoniorum''). Their present distribution suggests they have existed since before the breakup of Gondwana. They are the only living members of the suborder Coleorrhyncha, which first appeared in the Upper Permian, over 250 million years ago. Evolution Peloridiidae are the only extant family in the suborder Coleorrhyncha. Historically the Peloridiidae and their fossil kin were assigned to a variety of orders. In 1929 ...

Peloridiomorpha
Coleorrhyncha or Peloridiomorpha, also known as moss bugs or beetle bugs, are a suborder of Hemiptera and represent an ancient lineage of moss-feeding insects. They show some similarities to the Heteroptera but have been considered distinct. It has a single extant family, the Peloridiidae. They are in length, and feed on moss and liverworts. They have wings in some species which are reduced in others but all species are flightless and live in damp moss habitats and are associated with the distribution of ''Nothofagus'' trees in Australia, New Zealand, New Caledonia, and South America, which all were formerly part of the supercontinent Gondwana. Three other major families have been established on the basis of fossils: Progonocimicidae (Late Permian to Late Cretaceous) Karabasiidae (Jurassic-Early Cretaceous) and Hoploridiidae (Early Cretaceous), which have been found in both the Northern and Southern Hemispheres. The oldest member of Coleorrhyncha is '' Permoridium'' from the ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemiptera
Hemiptera (; ) is an order (biology), order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, Reduviidae, assassin bugs, Cimex, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking Insect mouthparts, mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.'' Visible Ink, 1998p. 1. which does not include other arthropods or insects of other orders such as Ant, ants, Bee, bees, Beetle, beetles, or Butterfly, butterflies. In some variations of English, all Terrestrial animal, terrestrial arthropods (including non-insect arachnids, and myriapods) also fall under the Colloquialism, colloquial understanding of ''bug''.

Sister Taxon
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomi ...

International Code Of Zoological Nomenclature
The International Code of Zoological Nomenclature (ICZN) is a widely accepted convention in zoology that rules the formal scientific naming of organisms treated as animals. It is also informally known as the ICZN Code, for its publisher, the International Commission on Zoological Nomenclature (which shares the acronym "ICZN"). The rules principally regulate: * How names are correctly established in the frame of binominal nomenclature * Which name must be used in case of name conflicts * How scientific literature must cite names Zoological nomenclature is independent of other systems of nomenclature, for example botanical nomenclature. This implies that animals can have the same generic names as plants (e.g. there is a genus ''Abronia'' in both animals and plants). The rules and recommendations have one fundamental aim: to provide the maximum universality and continuity in the naming of all animals, except where taxonomic judgment dictates otherwise. The code is meant to guid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomic Rank
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family (biology), family, order (biology), order, class (biology), class, phylum (biology), phylum, kingdom (biology), kingdom, domain (biology), domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of phenotypic trait, traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentatomoidea
The Pentatomoidea are a superfamily of insects in the Heteroptera suborder of the Hemiptera order. As Hemiptera, they share a common arrangement of sucking mouthparts. The roughly 7000 species under Pentatomoidea are divided into 21 families (16 extant and 5 extinct). Among these are the stink bugs and shield bugs, jewel bugs, giant shield bugs, and burrower bugs. Description The Pentatomoidea are characterised by a well-developed scutellum (the hardened extension of the thorax over the abdomen). It can be triangular to semielliptical in shape. The antennae typically have five segments. The tarsi usually have two or three segments. Shield bugs have prothoracic glands (in their thoraces, between the first and second pair of legs) that produce a foul-smelling liquid, which is used defensively to deter potential predators and is sometimes released when the bugs are handled. These prothoracic glands are also present in the nymphs, which are similar to adults except smaller ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lygaeoidea
The Lygaeoidea are a sizeable superfamily of true bugs, containing seed bugs and allies, in the order Hemiptera. There are about 16 families and more than 4,600 described species in Lygaeoidea, found worldwide. Most feed on seeds or sap, but a few are predators. The ash-gray leaf bug family ( Piesmatidae) is generally considered a member of the superfamily Lygaeoidea, but in the past it was sometimes placed in its own superfamily. Families These 16 families belong to the superfamily Lygaeoidea. The majority of them were considered to be part of the family Lygaeidae before Thomas J. Henry's work was published in 1997. * Artheneidae Stål, 1872 * Berytidae Fieber, 1851 (stilt bugs) * Blissidae Stål, 1862 * Colobathristidae Stal, 1865 * Cryptorhamphidae * Cymidae Baerensprung, 1860 * Geocoridae Baerensprung, 1860 (big-eyed bugs) * Heterogastridae Stål, 1872 * Lygaeidae The Lygaeidae are a family in the Hemiptera (true bugs), with more than 110 genera in four subfami ...
