Phylogenetic position of the Altaic fish
genus Oreoleuciscus in Leuciscinae
based on mitogenome sequences
38 species 204 genera (FishBase)leuciscin: Eurasian plus North American Notemigonus cryleucas
48 species 319 genera (FishBase)phoxinin: North American and Far Eastern species
Phylogeny based on morphology (Cavender and Coburn, 1992)
Leuciscinae
Widely distributed in Northern Hemisphere
Morphologically similar (even among different genera)
Important to consider the evolutional history of Leuciscinae
Central Asia and Far East
The genus Oreoleuciscus (Warpachowskii, 1889)
Endemic to inland lakes in western Mongolia and Tuva, the upper Ob River system within the Altai Mountain region of Siberia (Berg, 1962)
Planktonic algae, insects, invertebrates and fishes

The genus Oreoleuciscus is included in phoxinin (Cavender & Coburn 1992)
rather than Tribodolon and Pseudaspius
Oreoleuciscus formed a monophyletic clade with the Far Eastern phoxinins
Conclusion
Oreoleuciscus is closely related to the Far Eastern Phoxinus
Tribolodon, Pseudaspius and the Far Eastern Phoxinus
Tribolodon + Pseudaspius and Oreoleuciscus + Phoxinus were divided 49 Mya
Oreoleuciscus and Phoxinus were divided 34 Mya
Thank you for your attention !!
The genus Oreoleuciscus (Warpachowskii, 1889)
Endemic to inland lakes in western Mongolia and Tuva, the upper Ob River system within the Altai Mountain region of Siberia (Berg, 1962)
The range of Oreoleuciscus demarcates a highly ranked biogeographical unit that has a very depauperate and distinct ichthyofauna.
In the review of Eurasian cyprinid biogeography, Banarescu & Coad (1991) determined that the rank of this unit is equal to that of regions such as the entire Euro-Mediterranean or Central Asian regions.

High degree of morphological variability that obscures differences among species
Taxonomy of the genus Oreoleuciscus is controversial
Paucity of specimens from key geographical areas
Phylogenetic position of Oreoleuciscus
Oreoleuciscus is thought to be allied to the Eurasian cyprinid genera Pseudaspius and Tribolodon which are within the aspinin lineage of the subfamily Leuciscinae (Howes, 1984, 1991).
On the other hand, there is also the idea that Oreoleuciscus is rather closely related to the phoxinin lineage (Travers, 1989; Bogutskaya, 1990).
Thus, taxonomy of the genus Oreoleuciscus is controversial, in part because of the paucity of specimens from key geographical areas, and in part because there is high degree of morphological variability that obscures differences among species.
Determine complete mitochondrial (mt) genome sequences of Leuciscinae species
