Colour in life: body both dorsally and ventrally is dark brown. Infraorbital, postorbital and upper lip with yellow spots. Reddish-orange patches present on snout, sides of dorsum, abdomen, around vent and on limbs. Distinct reddish orange cross-bars on proximal end of tibia and tibiotarsal articulation. Juveniles darker than adults (Manamendra-Arachchi and Pethiyagoda, 2001).
Colour in alcohol: body dark brown. Irregular dark brown patches on dorsum. Belly dark brown or ashy-dark brown with few light ashy patches. Some specimens have light brownish markings around the vent, tibiotarsal articulation and tarsi.

Life History, Abundance, Activity, and Special Behaviors
Etymology: Uperodon nagaoi is named after Mr. Eijiro Nagao, President of Marusan Securities Co. Ltd. Of Japan, who is thanked for the Nagao Environmental Foundation's generous support of research into the amphibians of Sri Lanka (Manamendra-Arachchi and Pethiyagoda, 2001).
Uperodon nagaoi is found exclusively in tree-holes either alone or in mutualism relationship with at least two species of Poecilotheria sp. (Tarantula/ Tiger spiders) (Karunarathna and Amarasinghe, 2009).
Genetically, U. nagaoi is closely related to U. obscurus and U. palmatus; from these it was found to differ by an average uncorrected genetic distance of 5.6% (N = 6) and 4.0% (range 4.0–4.2%, N = 8), respectively (Garg et al.,2018; Wijayathilaka et al 2018).
