In life, the dorsum and lateral head are brown and have symmetrical, dark-brown markings with white patches. The upper and lower flanks are brown and share a similar marking and patch coloration as the dorsum and lateral head. There are white markings on the dark brown inguinal zone. Dorsally, the limbs are brown with white dots and dark-brown crossbars. Posteriorly, the thigh is dark-brown. The coloration of the venter is pale brown. The webbing is dark-brown (Meegaskumbura & Manamendra-Arachchi 2005).
In preservative, the dorsal side of the species is brown with symmetrical dark-brown markings. The interorbital bar is dark brown.

The tympanum is a yellowish brown color with the outer rim being brown. The mid-tympanum region is dark brown. The brown upper lip has white patches. Dorsally, the limbs are brown with white dots and dark brown crossbars. The posterior aspect of the thigh is dark brown. The venter is a pale yellowish-brown color.

Distribution and Habitat
Life History, Abundance, Activity, and Special Behaviors
All frogs of this genus Pseudophilautus are known terrestrial direct developers (Bahir et al. 2005).
The species epithet of P. hallidayi had honored the 1994 International Director of the IUCN and SSC Task Force on Declining Amphibian Populations, Timothy Richard Halliday. His work consisted of research on amphibians and contributing to advancing the understanding of amphibian population decline worldwide (Meegaskumbura & Manamendra-Arachchi 2005).
Pseudophilautus hallidayi and P. cavirostris are both sister species. A 12S and 16S divergence of 7.9% and 15.7% cyctochrome-b divergence test was used to differentiate these two species (Meegaskumbura & Manamendra-Arachchi 2005).
