Dallia
	Dallia pectoralis
Scientific classification
Kingdom:	Animalia
Phylum:	Chordata
Class:	Actinopterygii
Order:	Esociformes
Family:	Umbridae
Genus:	Dallia; T. H. Bean, 1880

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]

Dallia admirabilis Chereshnev, 1980
Dallia delicatissima Smitt, 1881
Dallia pectoralis T. H. Bean, 1880 (Alaska blackfish)

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]
