IUCN Red List

Although there is little information on the population and trend of this species throughout its range, data from limited field work suggests that this species is still relatively abundant, at least in the Salween River drainage in western Thailand. However, there is some taxonomic uncertainty that needs to be resolved, in as far as the conspecificity of the Mekong population is concerned. Given this taxonomic uncertainty and the limited knowledge available as to the global population size and trend, this species cannot be accurately assessed for now so is Data Deficient, but needs updating (IUCN 2010).
