Dallia (Blackfish) 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] The genus was named after American naturalist William Healey Dall. [3]

Species

Three species in this genus are recognized: [4]

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. [5] [6] [7] [8]

Fossil remains of Dallia are known from the Late Miocene near Homer, Alaska, suggesting they were found further south in the past. Pleistocene-aged fossil remains also suggest they ranged significantly more west in Siberia as well. [9]
