The complete mitochondrial genome of Epeus alboguttatus (Araneae: Salticidae)

Abstract

The complete mitochondrial genome of Epeus alboguttatus (Araneae: Salticidae) is 14,625 bp in length (GenBank accession number MH922026). It was predicted to consist of 13 protein-coding genes, 22 transfer RNA (tRNA) genes, 2 ribosomal RNA genes, and a putative control region. The gene composition and orientation of E. alboguttatus were identical to those found in other spider mitogenomes. The nucleotide composition shows heavily biased towards As and Ts, accounting for 77.59%. Twenty-two genes were in majority strand and 15 genes were in minority strand. ATT, ATA, TTA, and TTG were initiation codons, and TAA, TAG, and T were termination codons. Twenty-two reading frame overlaps and four intergenic regions were found in the mitogenome of E. alboguttatus. Ten tRNA genes lost the TΨC arm stems and had unpaired amino acid acceptor arms, whereas three tRNAs lacked the dihydrouracil (DHU) arm. Phylogenetic analysis indicated that E. alboguttatus is nested with Salticidae and recovered as sister to other five salticids.
