Abstract
The complete mitochondrial genome of Cheliceroides longipalpis Zabka (Araneae: Salticidae) is a circular DNA molecule of 14,334 bp in length (GenBank accession number MH891570), and contains a standard set of 13 protein-coding genes (PCGs), 2 ribosomal RNA genes, 22 transfer RNA (tRNA) genes, and an A + T-rich region. The gene orientation of C. longipalpis was similar to those found in other spider mitogenomes. The overall nucleotide composition is 36.5% A, 8.1% C, 12.9% G, and 42.5% T. Twenty reading frame overlaps and seven intergenic regions were found in the mitogenome of C. longipalpis. Thirteen tRNAs lack the potential to form the cloverleaf-shaped secondary structure. Ten PCGs start with ATN codons, two genes (cox2 and cox3) begin with TTG, and cox1 use AGA as initiation codon. Nine PCGs use usual termination codon of TAA or TAG, whereas the remaining four had an incomplete termination codon (T). The phylogenetic relationships of 14 spider mitogenomes based on the concatenated amino acid sequences of 13 PCGs showed that C. longipalpis is closely related to Plexippus paykulli, which is consistent with the traditional taxonomy.
