The complete mitochondrial genome and phylogenetic analysis of Phintella cavaleriei (Araneae: Salticidae)

The complete mitochondrial genome of Phintella cavaleriei is 14,325 bp in length, containing 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes, and a putative control region. The overall nucleotide composition is 35.04% A, 8.46% C, 13.41% G, and 43.09% T, with a...

Description
Summary:The complete mitochondrial genome of Phintella cavaleriei is 14,325 bp in length, containing 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes, and a putative control region. The overall nucleotide composition is 35.04% A, 8.46% C, 13.41% G, and 43.09% T, with a total of A + T content of 78.13%. Ten PCGs start with typical ATN codons, two genes (cox2 and cox3) begin with TTG, and cox1 use TTA as initiation codon. Ten PCGs use usual termination codon of TAA or TAG, whereas the remaining three PCGs had an incomplete termination codon (T-). Seven tRNAs (trnY, trnC, trnG, trnN, trnH, trnP, and trnV) lacked the TΨC arm stem, while two tRNAs (trnS 1 and trnS 2 ) lost the dihydrouracil (DHU) arm. Phylogenetic analysis based on 13 PCGs indicated that P. cavaleriei was closely related to Cheliceroides longipalpis, and clustered within Salticidae clade.
