|Scientific Name:||Microgomphus wijaya|
|Species Authority:||Lieftinck, 1940|
|Red List Category & Criteria:||Endangered B1ab(iii)+2ab(iii) ver 3.1|
|Reviewer(s):||Kalkman, V. & Clausnitzer, V. (Odonata Red List Authority)|
Rare and taxonomically interesting species. Recently known from only few localities (less than 10) in central and southwestern part of the island. Extent of occurrence estimated at less than 20,000 km², but the area of occupancy is estimated at less than 500 km². Its habitat - rivers and streams with rich surrounding vegetation in mid-hills is fragmented and under threat.
Additional exhaustive faunistic survey made by odonatologists and covering appropriate localities in different seasons is urgently needed.
|Range Description:||The species is found in Sri Lanka and is a rare endemic species. Recently known from only few localities in southwestern and central part of the island.
Some individuals present in large odonatological collection made by Naturhistorischen Museum Basle (Switzerland) and National Museum of Natural History - Smithsonian Institution (USA) (museum collections accessed by M. Bedjanic between 2005-2009). Also found during the author’s surveys in last years (2001, 2003).

|Population:||Detailed population numbers and trend are unknown but thought to be small and fragmented.|
|Habitat and Ecology:||The species inhabits rivers and streams with rich surrounding vegetation in mid-hills.|
|Major Threat(s):||Rivers and streams with rich surrounding vegetation in mid-hills are the type of habitat under treat. Destruction of primary and secondary rainforests, destruction of forest corridors along streams, pollution and other pressures on streams and rivers in the southwestern and central part of Sri Lanka are the major threat for exceptionally rich endemic dragonfly fauna of the island.|
Apart from the general conservation guidelines, no
"site specific single-species-oriented” conservation measures can be
proposed for the moment. General guidelines for protection of rich endemic dragonfly fauna of Sri Lanka include (1) establishment of network of new small protected areas and corridors in the 'wet zone' (mountains and the southwestern part of the country), (2) conservation of forest corridors along streams and rivulets outside protected areas in the wet zone and (3) effective execution of appropriate nature conservation measures in partly damaged declared protected areas (Bedjanic 2004).
