Geographic Range [top]
Range Description: Brachydiplax ophelia is endemic to Borneo. Lieftinck (1954) lists it as “universal” on the island, but although there are scattered records across the island it seems to be very local in occurrence. There are records from Sarawak (Laidlaw 1920, from "4th Mile, Rock road" a location probably now vanished under the state capital Kuching), Kalimantan (Lieftinck 1953) and one location in Brunei (Orr 2001, V. Kalkman pers. comm. 2007).
Countries occurrence:
Native:
Brunei Darussalam; Indonesia (Kalimantan); Malaysia (Sarawak)

Population [top]
Population: This appears to be a very scarce species. There are very few records, and the only recent ones are two from Brunei, both of single males. However it is a small insect that it is likely to be missed by non-expert collectors; it may be under-recorded.
Current Population Trend: Unknown
Additional data:
? Population severely fragmented: Unknown
Habitat and Ecology [top]
Habitat and Ecology: Little has been recorded on this species, Orr (2003) states that it occurs mainly in peat swamp and alluvial forest. It is certainly very local in occurrence. Orr’s record from Brunei (2001) was from a small pool in disturbed peat swamp forest, suggesting that the species can survive in disturbed forest habitats.
Systems: Freshwater
Threats [top]
Major Threat(s): Lowland swamp forest habitats in Borneo are threatened by clear-felling and plantation establishment, and in some areas by the spread of cities.
Conservation Actions [top]
Conservation Actions: More data is needed on this species, searches need to be made in swamp forest throughout Borneo. It is vital that the extent of disturbance that the species can tolerate is determined; for this reason searches should be made in a variety of swamp forest habitats, including secondary and highly disturbed ones. Once more locations are known for the species, it must be ensured that some of them at least are within protected areas.
