Adenomus is a small genus of true toads, with only two species, endemic to Sri Lanka. Adenomus kandianus was considered as extinct for 133 years, but was rediscovered in October 2009 in the Kandy area. Adenomus are slender toads that lack the supraorbital ridge (present in other Sri Lankan bufonids) and have smooth finger edges (versus granular). The largest species is Adenomus kelaartii where females can attain 50 mm (2.0 in) in snout–vent length.
