A new species of Rimboda Heller (Coleoptera, Curculionidae, Conoderinae, Othippiini) reared from Distylium racemosum Siebold & Zucc. in the Ryukyu Islands, Japan

Researchers have identified a new species of weevil, Rimboda saekii, from the subtropical forests of Amami-Oshima Island, Tokunoshima Island, Northern part of Okinawa Island, and Iriomote Island in Japan. This discovery marks a significant northward expansion of the genus Rimboda's known geographic range, which was previously limited to Indonesia, Malaysia, and the Philippines. The species was reared from Distylium racemosum (Hamamelidaceae), providing new insights into its ecological associations. The study includes detailed habitus photographs, 3D models, and illustrations of male and female genitalia, along with a comprehensive checklist of all known Rimboda species worldwide.
