Abstract

Binyo Penyilam is a unique wetland conservation area within the Sarawak Planted Forest Project zone in Sarawak’s Bintulu Division. A variety of forest and open habitats are present in the area; these are characterised. An annotated list of 61 species of Odonata from 11 families collected in the area to-date is presented. At least seven of these species had not been found in Sarawak prior to their discovery at Binyo Penyilam, of these four - Pseudagrion coomansi, Merogomphus femoralis, Brachygonia puella and Chalybeothemis fluviatilis - have still not been found elsewhere in the state; no other location is known for the genus Merogomphus in Borneo. Although under-sampling makes assessments of the conservation status of south-east Asian Odonata difficult, at least 16 of the species found at Binyo Penyilam can be considered to be of potential conservation concern, at least within Sarawak.
