Type material. Male holotype from Fazenda Escalvada , Mucuri [18°3'19.97"S 39°32'58.78"W], Bahia, Brazil, 11.IX.1979, A. C. Niella, deposited in SMNK.

Etymology. The specific name is a noun in apposition taken from the type locality. In Portuguese, escalvada is an adjective and means devoid of vegetation.

Diagnosis. Males of Corinna escalvada n. sp. differ from those of other species with tegular process inserted closely to the embolar base by the massive, wide base of RTA, without a median process on its prolateral surface ( Figs. 47–48 View FIGURES 43 – 48 ).
