The complete mitochondrial genome of the wolf spider Wadicosa fidelis (Araneae: Lycosidae).

The complete mitochondrial genome of the wolf spider Wadicosa fidelis was determined. It is a circular molecule of 14,741 bp in length and contains a standard set of 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs and a control region. The A + T content of the overall base composition of majority strand (J-strand) is 76.1% (T: 43.0%; C: 8.2%; A:33.1%; G: 15.7%). Start codons in all 13 protein-coding genes (PCGs) follow the ATN rule, except of four genes (COII, COII, ND4 and ND6), which have TTG start codon. The usual termination codons (TAA and TAG) are found from nine PCGs. However, COI, ND1, ND4L, ND5 had an incomplete termination codon (T). The control region (D-loop) is 1071 bp long with 67.9% A + T content, and contains a long tandem repeat region, which is comprising three full 215 bp copies and a partial fourth (87 bp) copy.
