Abstract

Trichonephila clavipes (Linnaeus, 1767) is known as a golden silk orb-weaver and belongs to the family Araneidae. T. clavipes is one of the few spider species whose genome has been reported and model organism for a molecular biology. Here, we present the complete mitochondrial genome sequence (mtDNA) of T. clavipes. The sequence was obtained using a long-read Nanopore technology and corrected with an Illumina technology. The circular genome is 14,902 bp in length, and the AT content was 77.21%. The T. clavipes mitochondrial genome contains 13 protein-coding genes (PCGs), 22 tRNA genes, and 2 rRNA genes. The majority of PCGs were found on the heavy strain.

Keywords: Araneidae; Golden silk orb-weaver; spider.
