|Scientific Name:||Vestalis luctuosa|
|Species Authority:||(Burmeister, 1839)|
|Red List Category & Criteria:||Near Threatened ver 3.1|
|Reviewer(s):||Kalkman, V. & Clausnitzer, V. (Odonata Red List Authority)|
This species was once common in Java, this may still be the case, but extensive habitat loss has occurred across the known range of the species. The only relatively recent published records of the species are from Bali, where it may be quite common. Without extensive sampling on Java the species has now to be considered as data deficient on that island. Overall it is difficult to assess this species, but as the number of currently known locations is low, it is close to Vulnerable status by criterion D2 and it is listed it as Near Threatened; hopefully fresh sampling on Java and Sumatra will allow it to be re-assessed as Least Concern in the near future.
|Range Description:||Vestalis luctuosa is known from Java (e.g. Lieftinck 1934, Schmidt 1934), south Sumatra (e.g. 1935, 1954) and Bali (e.g. Lieftinck 1953, Belle 1994).|
Native:Indonesia (Bali, Jawa, Sumatera)
|Number of Locations:||1-10|
|Upper elevation limit (metres):||2000|

|Population:||"Very common in Java" (Lieftinck 1954), but there is insufficient recent data to determine if this statement still holds. Judging by published records the species is not uncommon in Bali. In Sumatra it is known only from the extreme south, where it was quite common in the 1930s, but again there is little recent information, due to a lack of expert sampling in Sumatra in the intervening years.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Breeds in shady streams from sea-level up to about 2,000 m.|
|Major Threat(s):||Habitat loss through clear-cutting of forests.|
|Conservation Actions:||New data is needed from across the known range of this species for effective conservation planning. It was once a common species across much of its range; this may still be the case. Fresh searches need to be made in Java and Sumatra.|
