(depth about 20 cm), leaf litter and bark. In addition to the type specimen, some tadpoles (more than 5) and two adults of this species were also found. Theloderma stellatum was found on the same tree, and T. gordoni was recorded on hollow trees 50m distant. The general habitat was primary montane forest. It is not known whether or not this species can adapt to anthropogenic habitats.
There is no information on its abundance. It is known only from the holotype, and two other adults and some tadpoles found at the same time.
No information is available on threats to this species.
It has not been recorded from any protected areas. Surveys are needed to determine its geographic distribution, abundance, ecological requirements, threats and conservation needs.
