Abstract
Previous studies using mitochondrial DNA (mtDNA) genes suggest the black-tailed brush lizard, Urosaurus nigricaudus, which is a small-sized lizard from the peninsula of Baja California, Mexico, has 4 deeply isolated mtDNA lineages with sequence divergence ranging from 4% to 11.2%. We present its complete mitochondrial genome. This genome is 17,298 bp long and comprises 2 rRNAs, 22 tRNAs, 13 protein-coding genes, 1 L-strand origin of replication and 1 control region. The overall nucleotide content is A = 34.2%; C = 26.8%; G = 13.5%; T = 25.5%. The gene organization and features agree with the general vertebrate organization and that found in other lizards. The control region is 1909 bp long and is located between tRNAPro and tRNAPhe.
