This species is only known from subterranean streams in caves of Pang Mapha karst formation in north-western Thailand. Given the nature of the hydrological system and the likely limited extent of occurrence (considered to be much less than 2,000 km²), the species is assessed as Vulnerable (D2). Current and potential threats are tourism development and degradation of the surrounding watershed and water quality.
