Abstract

In 2019, one of the authors collected one female Cybister tripunctatus lateralis (Fabricius, 1798) along with other species of diving beetles in a wetland behind a paddy field in Fukutomi Town, Higashi-Hiroshima City. This is the second record of this species in this city. It is a relatively large aquatic beetle that inhabits ponds and has abandoned paddy fields rich in aquatic plants, from flatlands to low mountains. It was recorded in various places until around 1950, with one record of the species in Kurosechootada, Higashi-Hiroshima City on November 9, 1919 (Kameyama and Sugimori, 2020), but has decreased sharply since then. However, in recent years, sightings have increased all over the country, mainly in western Japan, and since there are a series of sightings in Higashi-Hiroshima other than this report, it is suggested that the population of this species is recovering and the distribution is expanding in Higashi-Hiroshima, similar to the other parts of the country. In the future, continuous sightings of this species in the wetlands of Higashi-Hiroshima City are expected.
