Pseudophilautus dimbullae was endemic to Sri Lanka, from the type locality "Queenwood Estate, Dimbullen, Ceylon", which is located at 1,500 m asl. The habitat that this species required is not known (Stuart et al. 2008); there is no mention of the habitat in the original paper (Shreve 1940).

This species is known only from the preserved holotype, collected in 1933 and described by Shreve (1940). It has not been rediscovered despite extensive searches and is presumed extinct. Breeding is believed to be through direct development (Stuart et al. 2008).

The reasons for extinction are not known, but habitat loss is thought to have been the major factor (Stuart et al. 2008).
