Kandyan Dwarf Toad

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 parotoid glands are relatively long, which is the single morphological trait that separates Adenomus kandianus from Adenomus kelaartii with shorter parotoid glands. The tympanum is submerged and poorly visible. The toes are partially to fully webbed; the partially webbed morphs were described 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 dorsum 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 tadpole 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. Gosner stage 36 specimen measures 27 mm (1.1 in) in total length.

Adenomus kandianus is known from montane cloud forests and tropical moist forests in and near hill streams at elevations of 1,100–1,879 m (3,609–6,165 ft) above sea level. The tadpoles develop in the streams.
