It is endemic to remnants of the Atlantic rainforest in the states of Alagoas, Paraíba, and Pernambuco in north-eastern Brazil.
[3] The specific name alagoana refers to Alagoas, the state where this species was first found.
The snout is short and truncate in dorsal and rounded in lateral view.
It lives in leaf litter and under fallen palm leaves, preferably in humid sites.
Habitat loss is probable major threat to this species.
