This species is currently known from several rovinces in southeastern Thailand. There are records from: Khao Soi Dao Wildlife Sanctuary and Khao Soi Dao Tai Mountain, in Chantaburi Province, at 600-1,000m asl; Namtok Phliu National Park, in Khlung District, Chantaburi Province; Pang Si Da National Park, in Muang Sa Kaeo District, Sa Kaeo Province, at 600m asl (Stuart et al., 2006); and Khao Yai National Park, in Pak Chong District, Nakhon Ratchasima Province, at 900-1,000m asl (Kongjaroen and Nabhitabhata, 2007). In addition, records of tadpoles attributed to Megophrys parva from Khao Ang Rui Ni Wildlife Sanctuary, in Chachoengsao and Chon Buri Provinces (Inthara et al., 2004) probably refer to this species (Y. Chuaynkern, pers. comm.). It might occur a little more widely, but the species is probably restricted to the uplands of southeastern Thailand, the closely-related Xenophrys auralensis occurring in nearby Cambodia (B.L. Stuart pers. comm.).
Habitat and Ecology
This species has been found at night on boulders and rock outcrops above swift, rocky streams with waterfalls in hilly evergreen mixed with bamboo forest, and on leaf-litter near swift, rocky streams in disturbed vegetation next to an abandoned road through hilly evergreen forest (Stuart et al., 2006). However, there is no evidence that it can adapt to seriously disturbed habitats (B.L. Stuart pers. comm.). The tadpoles live in streams (Stuart et al., 2006).
It can be a locally abundant species in suitable habitat.
No information is currently available on threats to this species. All records so far are from well-managed protected areas.
It has been recorded from Khao Soi Dao Wildlife Sanctuary, Namtok Phliu National Park, Pang Si Da National Park, Khao Yai National Park, and probably Khao Ang Rui Ni Wildlife Sanctuary (Stuart et al., 2006; Kongjaroen and Nabhitabhata, 2007; Inthara et al., 2004). Surveys are needed to determine its geographic distribution, adundance, ecological requirements, threats and conservation needs.
