Rediscovery
As there had been no record of the species since 1872, it was listed as extinct by the IUCN in 2004. However, in June 2012 it was announced that almost three years earlier, in October 2009, the species was rediscovered in the in Sri Lanka. In light of the discovery, the species was reclassified in 2012 as in the . Another extant population was reported in 2014 from Forest Reserve.
Description
Adult males measure 30–35 mm (1.2–1.4 in) and adult females 40–45 mm (1.6–1.8 in) in snout–vent length. The are relatively long, which is the single morphological trait that separates Adenomus kandianus from with shorter parotoid glands. The is submerged and poorly visible. The toes are partially to fully webbed; the partially webbed morphs were as a separate species, Adenomus dasi, but because the morphs show negligible genetic differences,A. dasi is not longer recognized as distinct. The fingers have no webbing.
The is yellowish brown; the head is more reddish compared to the body. A tiny gold-coloured vertebral stripe is present. The parotoid glands are chocolate or dark brown. The lips have black and gold dots. The venter is gold. An hourglass-shaped pattern of tubercles on the dorsum may be present.
The has relatively long body (39% of total length). The body is flattened and wide anteriorly, accommodating a ventral sucker disc that covers more than half of the body. The eyes are bulbous. 36 specimen measures 27 mm (1.1 in) in total length.
Habitat
Adenomus kandianus is known from montane and tropical moist forests in and near hill streams at elevations of 1,100–1,879 m (3,609–6,165 ft) . The tadpoles develop in the streams.
