Dallia

Dallia
Scientific classification
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Esociformes
Family: Umbridae
Genus: Dallia

Dallia is a genus of mudminnows native to Russia and Alaska. Molecular data indicates the genus is more closely related to Esox and Novumbra than Umbra.[1] [2] Dallia diverged from Novumbra + Esox approximately 66 million years ago.[2]

Species

Three species in this genus are recognized:[3]

Mitochondrial sequence data was examined from D. pectoralis and D. admirabilis and did not indicate that speciation within the genus in Russia; however, genetic isolation within Alaska for populations of D. pectoralis could be high and associated with karyotype differences.[4][5][6][7]
