This species is known with certainty only from Kohtao Island, Thailand. However, the tradition has become to assign most striped caecilians from mainland Southeast Asia to this name, as mapped. The attributed range of this species is Peninsular and Mainland Thailand, southeastern Myanmar, Lao People's Democratic Republic, Cambodia and Viet Nam. However, this requires further examination, and the taxonomy might be faulty. Specimens from Yunnan in China are attributed here to Ichthyophis bannanicus.
Habitat and Ecology
It is known to inhabit evergreen forest and streamside gallery forest, as well as agricultural lands and urban areas. A population of Ichthyophis cf. kohtaoensis from the Mekong valley, northeastern Thailand, was found in various terrestrial macrohabitats including open scrubs, gallery forests and open secondary forests. In the dry season, individuals of this population were found mainly in soil but in the rainy season they were also detected in leaf litter or rotten vegetation (Kupfer et al. 2005). This is an oviparous species with terrestrial eggs and aquatic larvae in forest streams and pools. The clutch size for the population from the Mekong Valley ranges from 32-58 eggs (Kupfer et al. 2006). It is considered to be an adaptable species.
There are places within its range where it appears to be locally abundant. In the Mekong Valley, Thailand, individuals have been recorded at low densities (median 0.08 individuals/m²) (Kupfer et al. 2005).
It is an adaptable species that is unlikely to be facing any significant threats.
It occurs in many protected areas.
Red List Status
Least Concern (LC)
This is a very poorly circumscribed species in need of taxonomic review (M. Wilkinson pers. comm.). Old records of Ichthyophis glutinosus in Southeast Asia are tentatively included here, with the expectation that further taxonomic research will separate this species into several taxa.
