Previously unpublished Odonata records from Sarawak, Borneo, part IX: More Odonata from Limbang Division, including the first records from Gunung Buda National Park

Records of Odonata made in Limbang Division in Sarawak during three surveys in 2021- 2022 made possible by funding from the International Dragonfly Fund are reported. All locations surveyed are within Limbang District and are grouped into two categories: locations surveyed on day trips from Limbang Town and locations in the Sungai Mendalam area further inland. All locations are in the lowlands of the division. The lowlands of Limbang Division had not been well studied for Odonata and the results presented here include 50 first records for Limbang Division, bring the total number of species known from the division to 173. In fact slightly more species were recorded during the 2021-2022 surveys than had been recorded from the division prior to 2021. Three of the new additions for Limbang are also first records for Sarawak (Libellago phaethon, Rhinocypha humeralis and Oligoaeschna platyura). The discovery of a large population of Macrogomphus phalantus not far from Limbang town is another significant result of the 2021-2022 surveys and is discussed in some detail. Other notable records include Dysphaea lugens, Coeliccia kenyah, the black form of Copera vittata, Argiocnemis rubescens rubeola, Teinobasis cryptica, Macrogomphus sp., Chlorogomphus sp., the true Pornothemis serrata and Pornothemis starrei. This report includes the first records of Odonata from Gunung Buda NP (a checklist is given in the appendix), where 76 species have been found so far.
