Abstract

Heptathela kimurai (Kishida, 1920) is a spider that belongs to the family Heptathelidae which is a basial lineage of spiders. The molecular information of ancestral species belonging to families like Heptathelidae is comparatively limited when compared to spider species from derived families. Here we present the complete mitochondrial genome sequence (mtDNA) of H. kimurai. The sequence was obtained using massively parallel sequencing technology. The circular genome was 14,224 bp in length, and the AT content was 69.53%. The H. kimurai mitochondrial genome contains 13 protein-coding genes (PCGs), 21 tRNA genes, and 2 rRNA genes. The majority of PCGs were found in the heavy strand.

Keywords: Kimura-gumo(japanese); basal lineage of spider; long-read sequencing; phylogenetic tree.
