The complete mitochondrial genome of Chilean sea urchin Loxechinus albus, the single species of the genus Loxechinus, is determined. The circular mitogenome is 15,709 bp in length containing 2 rRNA, 22 tRNA and 13 protein coding genes as well as the control region. The gene order is identical to those of described Camarodonta species. There are 24 bp gene overlaps at 6 locations and 124 bp intergenic spacers at 17 boundaries. The nucleotide composition of the genome is 31.2% A, 22.3% C, 29.7% T, and 16.8% G. The A+T bias (60.9%) is similar to that of P. lividus (60.3%) but slightly higher than those of strongylocentrotid species (58.8-59.8%). The mitogenome sequence of L. albus will provide valuable information on the phylogeny and evolution of the genus Loxechinus in relation to other Camarodonta sea urchins.
