Rangala Sonerila (Sonerila firma)

The Rangala Sonerila was described in 1879, originally as a variety of another species, Gardner’s Sonerila (Sonerila gardneri Thwaites).

The species was endemic to the island of Sri Lanka, where it was apparently restricted to a very small area in montane forest in the Kandy District, it is now considered extinct. [1]
