The complete mitochondrial genome of a nursery-web spider Dolomedes angustivirgatus (Araneae: Pisauridae)

Abstract

The complete mitochondrial genome of a nursery-web spider Dolomedes angustivirgatus is 14,783 bp in length and contains a standard set of 37 genes including 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs and a putative control region. The A + T content of the major strand is 77.0%. All the protein-coding genes are initiated by typical ATN codons, except for COII and COIII, which use a special start codon TTG. The truncated stop codon (T) occurs in ND4L, whereas the rest 12 genes end with the canonical stop codon (TAA and TAG). 15 tRNAs cannot be folded into typical cloverleaf-shaped secondary structure. The control region is 1084 bp in length and contains a long tandem repeat region. The result of phylogenetic analysis show that D. angustivirgatus is nested within Lycosoidea and recovered as sister to the cluster of three wolf spiders (Lycosidae).
