This species ranges widely in south-east Asia, from Viet Nam and the Lao People’s Democratic Republic, to Thailand and Peninsular Malaysia, Singapore and Sumatra, the Anambas Islands and the Natuna Islands (Indonesia). It is also present on the islands of Phuket, Langkawi, Penang and Tioman. It has not been recorded from the Cardamom Mountains in Cambodia. It occurs up to 1,200m asl.
Habitat and Ecology
It inhabits streams with gravel and boulders in primary and secondary evergreen forest. Males build a nesting hollow in a sandy streambed area, and the larvae develop in streams.
The population status of this species is locally variable, ranging from uncommon in western Thailand to very common in areas where harvesting does not occur in Peninsular Malaysia. It is generally less common in easily accessible areas near human habitation than in similar inaccessible areas, indicative of depleted populations due to harvesting. Cessation of harvesting leads to population recovery in five to 10 years (P. van Dijk pers. comm.).
The major threat to this species is intensive collection for consumption at subsistence levels, and for local, national and international trade. Some populations have also probably been eliminated locally due to forest clearance.
This species inhabits a great number of protected areas throughout much of its range, and is protected by the Wild Animals Reservation and Protection Act (WARPA), 1992, in Thailand. There is a need to ensure that the harvesting of this species from the wild is managed in a sustainable manner (this species could benefit from commercial farming). Clarification of the taxonomy of the blythii complex is necessary to identify cryptic species of conservation concern.
Red List Status
Near Threatened (NT)
Listed as Near Threatened because this species is in significant decline (but at a rate of less than 30% over ten years) because it is being over-harvested for food and because its habitat is shrinking, making the species close to qualifying for Vulnerable.
This form is undoubtedly a complex of many species.
