Odonata from the Glenealy Belaga Oil Palm Plantation Area, Belaga, Kapit Division, Sarawak, Borneo

Belaga District in Sarawak’s Kapit Division has been poorly studied for Odonata, with almost all work done in the district at altitudes of 700-1400m a.s.l. in mountainous terrain. Here we describe the results of sampling of Odonata carried out at the Glenealy Belaga Oil Palm Plantations, located just below the Dulit Range in Belaga District, conducted in May 2024. The sampled sites are in a relatively (for Belaga District) low lying area (sampled sites in the range ca. 160-230m a.s.l.). The plantation straddles the Belaga River and includes areas of High Conservation Value Forest and a riparian buffer around the Belaga River. Sampled locations in the three estates forming the plantation are listed and indicated on a map. All 53 species collected during the survey are listed, with additional comments where appropriate. Five of the species were recorded from Kapit Division for the first time and a further 15 (for a total of 20) were recorded from Belaga District for the first time. The most significant records are those of Coeliccia kenyah, Oligoaeschna platyura, Macromia corycia and the true Pornothemis serrata, these are discussed in the Discussion.
