To investigate the current mosquito fauna on Sado Island, we conducted surveillance in the Oosado mountainous area and the Kuninaka plain area from July 30 to August 3, 2019. In total, 20 species belonging to nine genera were collected. Among these, nine species in six genera were newly recorded on Sado Island. We also determined partial nucleotide sequences of the cytochrome c oxidase subunit I (COI) gene for 87 individuals of the 20 species and assessed the genetic divergence of their populations on Sado Island and the degree of differentiation between the Sado Island populations and those from mainland Japan or the Ryukyu Archipelagos.
