Adenomus

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.

Species.
There are two species:
The species are syntopic in parts of their range, but generally speaking "Adenomus kandianus" is a lower-altitude species whereas "Adenomus kelaartii" is a high-altitude species.
A third species, "Adenomus dasi" (Das's dwarf toad) was recognized in 2015 as being a synonym of "Adenomus kandianus"; the two show some morphological differences but negligible genetic divergence.
