New Species and New Distributional Records of the Genus Microvelia Westwood (Hemiptera: Heteroptera: Veliidae) from the Japanese Ogasawara Islands, with an Illustrated Key to Ogasawaran Species

Microvelia (Pacificovelia) amphitrite new species is described from the Japanese Ogasawara Islands. In addition, some specimens identified as M. douglasi Scott, 1874 and previously reported by different authors from the Ogasawara Islands were examined and recognized as misidentifications actually belonging to M. yoshitomii Watanabe, 2023 and the new species herein described. These results indicate that M. douglasi is not distributed in the Ogasawara Islands. In addition, M. yoshitomii is herein reported for the first time from nine islands in the archipelago. An illustrated key to Ogasawaran Microveliinae species is provided. Field surveys revealed that two species of Microvelia in the Ogasawara Islands prey on arthropods across several taxa, more than half of which are alien species.
