"The I.cardamomensis species is only the second caecilian species ever discovered in Cambodia. The other is the striped Koa Tao Island caecilian, I. kohtaoensis, which is also found in, Laos, Myanmar, Thailand, and Vietnam.

These discoveries are important to demonstrate that much of Cambodia's biodiversity remains unknown and unstudied by science, and many more areas need to be searched," Thy said.

The forested Cardamom Mountains Range represents some of the largest remaining areas of habitat for more than 80 threatened species, including Asian elephant and gaur.

Thy said in recent years the Cardamom region had revealed its extensive reptile and amphibian diversity, including frogs, turtles, lizards and crocodiles.
