Dorsal surface chocolate brown with unequal dark patches and small pale spots.

The species resides in high altitudes and is limited in distribution due to habitat destruction.

In Sri Lanka where the Corrugated Frogs are located, rainfall per year has been declining especially in the western slopes.

This has caused increasing dry periods that threaten Lankanectes Pera the existence and well being of the species.

These factors greatly increase the risk of forest fires that further damage the frog's habitat.

The frog species currently resides in the Knuckles Mountain Forest Reserve.

This reserve faces threats that include extensive agricultural practices, illegal cardamom plantations, and the restless pollution from pesticide use.

The unregulated research work and construction of resorts and other houses, uncontrolled tourism, and human set forest fires continue to be growing concerns in the efforts to save the environment of the Corrugated Frogs along with the species itself.

[6] The Corrugated Frogs is currently a critically endangered species and due to its specialized habitat, it requires immediate conservation efforts if it is not going to go extinct.

[7] The Corrugated Frog species is restricted to streams which flow through high peaks mountain forests.

They are mainly found in the Knuckles Mountains, although they have also been spotted in the Dothalugala, Bambrella, and Riverstone regions of Sri Lanka.
