The genomes are circular molecules of 16,457 bp and 16,460 bp in length, Accepted 17 March 2016 respectively, including the 37 genes typically found in other squirrels. The AT content of the overall base composition is 63.2% for both species. The length of control region for C. lateralis is 1009 bp with 62.8% KEYWORDS Golden-mantled ground AT content; the corresponding values for U. richardsonii are 1012 bp and 62.0% AT content.

The phylogenetic relationship of the typical rodent-type arrangement of their mitocondrial family Sciuridae has been revised and discussed based on genomes, being circular molecules of 16,457 bp and 16,460 bp molecular markers (Harrison et al. 2003; Herron et al. 2004; in length, respectively. Each encoded the 37 genes typically Helgen et al. 2009). We determined the sequences of the found in other squirrel species. The AT content of the overall complete mitochondrial genomes of Callospermophilus lateralis base composition is 63.2% for both species. The length of (¼Spermophilus lateralis) and Urocitellus richardsonii control region of C. lateralis is 1009 bp with 62.8% AT content (¼Spermophilus richardsonii) (Rodentia: Sciuridae) to analyze whereas the length of control region of U. richardsonii is the gene arrangement and to further explore the phylogen- 1012 bp with 62.0% AT content.
