Characterization of complete mitochondrial genome of Evarcha coreana (Araneae: Salticidae)

Abstract

The complete mitochondrial genome of a hunting spider Evarcha coreana was determined. The circular mitogenome is 14,333 bp in length (GenBank accession number MK381265), and contains 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA genes, and a putative control region. The orientation and gene order of E. coreana are identical with other spider mitogenomes. The AT content of the overall base composition is 75.86%. Twenty-two genes were in the major strand and 15 genes were in minor strand. Five intergenic regions and 25 reading frame overlaps were found in the mitogenome of E. coreana. Seven tRNA genes lost the TΨC arm stems, whereas three tRNAs lacked the dihydrouracil (DHU) arm. The control region is 697 bp in length with an A + T content of 81.06%. ATA, ATT, TTA, and TTG were initiation codons, and TAA, TAG, and T were termination codons. Phylogenetic analysis was performed using 13 PCGs with other spiders of the family Salticidae and it was seen that E. coreana is closely related to Telamonia vlijmi and Plexippus paykulli.
