Ostariophysi is the second largest superorder within Teleostei. It contains five orders: Gonorynchiformes, Cypriniformes, Characiformes, Siluriformes, and Gymnotiformes. Resolving the higher-level relationships among ostariophysan and related fishes will aid in resolving basal teleostean divergence and provide basis to historical biogeographic analysis of major freshwater fish groups. In this study, we report the complete mitochondrial (mt) DNA sequences for eleven ostariophysan fishes and the… 

Evolutionary history of Otophysi (Teleostei), a major clade of the modern freshwater fishes: Pangaean origin and Mesozoic radiation

The present timetree demonstrates that survival of the ancestral lineages through the two consecutive mass extinctions on Pangaea, and subsequent radiations during the Jurassic through early Cretaceous shaped the modern familial diversity of otophysans.


The origin and early diversification of this clade is reexamine based on a comprehensive time‐calibrated, molecular‐based phylogenetic analysis and event‐based approaches for ancestral range inference of lineages, which demonstrate Siluriformes is never sister to Gymnotiformes and Characiformes are most likely nonmonophyletic.

A Time-Calibrated Mitogenome Phylogeny of Catfish (Teleostei: Siluriformes)

The chronogram shows that siluriforms have a Pangaean origin, at least as far back as the Early Cretaceous, and the inferred timeline of the basal splits corroborates the “Out-of-South America” hypothesis and accords well with the fossil record.

A molecular phylogeny of Schizothoracinae (Teleostei: Cypriniformes: Cyprinidae) based on 12 protein-coding mitochondrial genes and RAG1 gene analysis

The results indicated that both of the data sets supported a non-monophyletic relationship due to involving of species of Barbinae, and the phylogenetic relationships based on mtDNA genes were more reliable than that inferred from RAG1 gene.

Molecular Phylogeny of the Opsariichthys Group (Teleostei: Cypriniformes) Based On Complete Mitochondrial Genomes.

Tree topologies show that a monophyletic group containing Parazacco, Candidia, Nipponocypris, Zacco, and Opsariichthys should belong to the Opsariicthys group, and strongly support that Candidia and NIPPonocy Pris should be regarded as distinct genera within the opsariichthyinae group.



Interrelationships of the ostariophysan fishes (Teleostei)

The extent of sympatry, together with the widespread distribution of ostariophysan lineages, suggests that the group is older than previously supposed, and hypotheses of relationships implies that many of the extent characiform lineages evolved before the separation of Africa and South America.

Early Biogeographic History of Ostariophysan Fishes

It is postulate that ostariophysans originated in South America in the earliest Cretaceous and there split into two sister groups, the Cypriniformes and Siluriformes, and that South America is the most likely center of origin for the group.

A 28S rRNA-based phylogeny of the gnathostomes: first steps in the analysis of conflict and congruence with morphologically based cladograms.

In maximum parsimony trees, nodes congruent with those of the morphologically based cladogram were found to be robust (chondrichthyans, neopterygians, euteleosteans), but some expected monophyletic groups were not finding to be so (lissamphibians, tetrapods, osteichthyans).

A mitogenomic perspective on the basal teleostean phylogeny: resolving higher-level relationships with longer DNA sequences.

This work reexamined the interrelationships of the five major, basal teleostean lineages using mitogenomic data for which five alternative phylogenetic hypotheses have been previously proposed on the basis of both morphological and molecular analyses and confidently rejected all of these hypotheses with high statistical significance.

Origin of the Weberian apparatus and the relationships of the ostariophysan and gonorynchiform fishes. American Museum novitates ; no. 2428

It is concluded that the resemblances between the two groups of fishes suggest derivation from a common stem, and the phylogenetic integrity of the included species is indicated more by the existence of this bony otophysic connection than by the presence of any other single feature.

Mitochondrial Molecular Clocks and the Origin of Euteleostean Biodiversity: Familial Radiation of Perciforms May Have Predated the Cretaceous/Tertiary Boundary

The explosive radiation of perciform families in the early Cenozoic was not supported by the mitochondrial sequence data and molecular methods are expected to provide new insights into macroevolutionary history of vertebrates which has been established on the basis of fossil evidence.

Use of mitogenomic information in teleostean molecular phylogenetics: a tree-based exploration under the maximum-parsimony optimality criterion.

It is concluded that judicious choice of mitochondrial genes and appropriate data weighting, in conjunction with purposeful taxonomic sampling, are prerequisites for resolving higher-level relationships in teleosts under the maximum-parsimony optimality criterion.

Ostariophysaln Zoogeography: an Alternative Hypothesis

The alternative hypothesis states that the characoid prototype evolved from a gonorynchiform ancestor in the Oriental Region in Upper Jurassic times. Shortly afterward, the siluriform fishes

A molecular and morphological perspective on the phylogenetic relationships of the otophysan fishes.

A sister group relationship between the Gymnotoidei and Siluroidei, which together form a sister group to the Characiformes, is supported, which represents the earliest phylogenetic split within the Otophysi.
