Abstract
Data reported from Northern Canada were until recently the only available data on the genetic characteristics of the oribatid mite Ameronothrus nigrofemoratus, which has a circumpolar distribution on the coasts of Arctic seas. A partial cytochrome oxidase I gene (COI) mtDNA sequence was examined in mites morphologically assigned to this species from the Kolguev Island. Two highly divergent phylogenetic lineages of A. nigrofemoratus (7% divergence) were revealed, neither of which was found on the Canadian coast. Four COI amino acid substitutions distinguished one of the lineages from North American A. nigrofemoratus, corresponding to the degree of difference between A. nigrofemoratus and its sister species A. lineatus.
期刊介绍：
Doklady Biological Sciences is a journal that publishes new research in biological sciences of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia in the form of short articles. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
