Research is needed to confirm the taxonomic status of the species. Further intensive survey is required to confirm whether any individuals of the species still remain in the wild.

Location Information

This fish is likely endemic to Java as it has only been recorded from Surakarta, possibly from the Bengawan Solo basin, in Central Java. The species was originally described by Bleeker (1855) based only on a single specimen, which also constitutes the last and only record for the species to date. In consequence, the geographical range of this fish can not be determined for certain.

Geographic Range

Possibly Extinct


Population Information

No information is available about the current population status and its trend, given that the species original description is the only reference for the species. If this species is still extant then there are estimated to be under 50 mature individuals. However, since the last record of this species took place more than a century ago (1855), the species is considered Possibly Extinct. Nevertheless, the absence of subsequent records for this species may simply be due to the lack of intensive ichthyological survey conducted in the Bengawan Solo basin.


Information about threats to the species is unknown. Nevertheless, similar to other fishes inhabiting river basins in Java, this species has likely been impacted by habitat loss or degradation primarily due to urbanisation, agricultural expansion, and industrial development commonly occurring throughout Java, as well as pollution resulting from such activities.
