The family lacks a close relationship with the Scorpaeniformes, owing to the posterior extension of the infraorbital in the former not being homologous with the scorpaeniform suborbital stay. Proceedings of the Academy of Natural Sciences of Philadelphia, 157: 137-147. However, with the exception of a few [homoplastic] characters (e.g., mobile premaxilla and posterior myodome extending into basioccipital), all others are synapomorphies at different prim itive levels of Teleostei (see Arratia, 1999; Arratia and Tintori, 1999).

The following from Lecture 5 - Review osteogossomorph teleosts - sister group of rest of the extant teleostei: Leptocephalus larvae have an elongate, highly compressed and nearly transparent body. Introduction They are placed as Teleostei incertae sedis. Teleosts, despite their incredible diversity, form a definable group with a recognizable ancestry. This clade is more closely related to a taxon formed by Roestes and Gilbertolus based on seven non-ambiguous synapomorphies. Moreover, the deep branches of the acanthomorph tree are still largely unresolved, with strong disagreement between studies. It is diagnosed as a monophyletic group on the basis of three synapomorphies: 1) a post-epioccipital process that reaches the In this regard, 360 morphological characters .

Halecomorphi is a taxon of ray-finned bony fish in the clade Neopterygii.The sole living Halecomorph is the bowfin (Amia calva), but the group contains many extinct species in several families (including Amiidae, Caturidae, Liodesmidae, Sinamiidae) in the order Amiiformes, as well as the extinct orders Ionoscopiformes, Panxianichthyiformes, and Parasemionotiformes. Characidae, one of the most diverse families of Characiformes and one of the largest clades of fishes in the world, has a complex taxonomic background, with one issue being the placement of various genera, including Gymnocorymbus. See all. Stenolicmus sarmientoi is described as a new genus and species of the trichomycterid subfamily Sarcoglanidinae, from the RíAo Mamoré Basin, Bolivia. In addition to the five synapomorphies commonly referred in the literature, there is another potential Heptapterinae synapomorphy: the well-developed maxilla forming a completely closed, deep tube to enclose the base of the maxillary barbel.

However, based on the resulting phylogeny, the genus Rasbora has been proven to be a monophyletic group supported by five synapomorphies. B6, University of Liège,. A second clade includes the members of the tribe Heterocharacini (Lonchogenys(Heterocharax Hoplocharax)) as the sister-group of Gnathocharax, supported by seven non-ambiguous synapomorphies. Synapomorphies of the postcranium: Fins supported by lepidotrichia - dermal fin rays developed from modified rows of scales.. 1994; 12S and 16S mitochondrial genes) did not test the monophyly of the . This classifi cation and account of synapo- morphies that diagnose monophyletic groups is a beginning, not an end, to the larger effort of dealing with the phylogeny of Teleostei as a whole. In the most comprehensive phylogenetic analyses of the Characidae, a relatively low number of species was analyzed (about a 15%) and there are many internal clades with very low support and morphological synapomorphies (Mirande, 2010; Mirande et al., 2011, 2013). Teleostei / t ɛ l iː ˈ ɒ s t iː aɪ / (Greek: teleios "complete" + osteon "bone"), members of which are known as teleosts / ˈ t ɛ l iː ɒ s t s /, is, by far, the largest infraclass in the class Actinopterygii, the ray-finned fishes, containing 96% of all extant species of fish.Teleosts are arranged into about 40 orders and 448 families.Over 26,000 species have been described.

STEPIEN The systematic and biogeographic relationships of the teleost family Clinidae (commonly known as kelpfishes or klipfishes), an antitropically distributed group of nearshore fishes characterized by widespread ecological variation, were an- alyzed using allozyme and morphological characters. The major differences between the Teleostei and the Holostei occur mainly in the head and the tail. Byrappa Venkatesh, Mark V. Erdmann, and Sydney Brenner. These events can explain our basal synapomor- ance events) found for the area relationships proposed here, phies (vicariances) for all areas and for the freshwater clade as well as other lineages with marine ancestors (Bloom and (subgenera Jenynsia and Plesiojenynsia). Teleost. Their monophyly was established by Patterson and Rosen (1977) based on only two synapomorphies: the presence of an ethmopalatine bone roofing the floor of the nasal capsule (a uniquely ichthyodectiform element in the ethmoid region), and uroneurals covering the lateral sides of the preural centra (Patterson and Rosen, 1977; Stewart, 1999). Molecular synapomorphies resolve evolutionary relationships of extant jawed vertebrates. Ten osteological synapomorphies support monophyly of the Leiognathidae, involving modification of the ribs, gill arches, palatoquadrate, median fins and branchiostegals. The teleost kidneys have a complex structure consistent with their multiple functions including serving as the site of osmoregulation and acid-base regulation (Perry, 2011), and the head kidney, which lacks glomeruli, as the primary hemopoietic tissue (Fänge and Nilsson, 1985) reticuloendothelial system (Zapata and Cooper, 1990) as well as an essential endocrine organ (releasing . .

Several hypotheses supporting monophyly of the Teleostei on the basis of synapomorphies have been produced over the last 30 years. The phylogenetic position of the family Dactylopteridae is inferred cladistically. The basal synapomorphies (vicari- Renno 2006). A cladistic analysis of the gobiid fish genus Gobionellus primarily using characters of the postcranial axial skeleton and the cephalic lateralis system gave evidence that the genus as historically conceived is polyphyletic. The Teleostei are the most speciose group of vertebrates, with more than 32,000 living valid species that constitute more than 99 % of Recent actinopterygian species [].The group shows enormous taxonomic diversity, together with a noteworthy variety of morphological features that have enabled life in very different aquatic habitats including freshwater, brackish, and marine environments [2, 3].
