Based on the extensive collections which have failed to record this species the EOO is less than 5,000 km². It is only known to occur at one locality (type locality). There is declining quality of habitat due to potential impacts from trawling, pollution with sewage output from towns and eutrophication from decay of water hyacinth rotting-down after cutting programme. It is therefore assessed as Endangered.
Previously published Red List assessments:
1996 Endangered (EN)
