Manamendra-Arachchi and Pethiyagoda (2005) comment that "zal expresses completely our sadness and frustration at the loss of this and so many other endemic amphibians in Sri Lanka."

Endemic to Sri Lanka and known only from the general type locality "Ceylon". The habitat requirements of this species are not known (Stuart et al. 2008).

This species has been found only at the type locality and is known only from the holotype and two paratypes, described by Manamendra-Arachchi and Pethiyagoda (2005). It has not been collected or recorded since before 1947; despite extensive searches Pseudophilautus zal has not been rediscovered and is presumed extinct. It is believed to have been a direct developer, as is the case for other members of the genus Pseudophilautus (Stuart et al. 2008).

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