Bossuyt and Dubois (2001) also suggested that since many new Sri Lankan species of Kirtixalus remain to be described, the name Pseudophilautus stellatus should be used to describe another species from the Nuwara Eliya area, with characters matching those of Kelaart's (1853) description, and that a neotype be collected. Since the holotype cannot be found, Manamendra and Pethiyagoda (2005) have instead put forward that Pseudophilautus stellatus should be considered a valid, extinct species, and that another name be used for any similar species.
In 2013, L.J. Mendis Wickramasinghe and colleagues announced its rediscovery nearly 160 years later; these striking individuals were found in inaccessible, high elevation cloud forests in the Peak Wilderness of Sripada World Heritage Site. Despite being found in a protected area, the area is suffering from forest dieback, expanding tea plantations, illegal mining and the expansion of invasive species, so it continued survival is not assured. The study recommends listing the species as "Critically Endangered" (Wickramasinghe et al 2013).
