Remarks.

The examined specimens match the description of Ulmer (i.e., tibial spur formula 1,2,2), unlike specimens examined by Quinteiro and Calor (2015), for states of Bahia, Mato Grosso, Paraíba, and Rio Grande do Norte, which presented tibial spur formula 0,2,2. This species is widely distributed in Brazil, including several records in the Northeast region ( Quinteiro and Calor 2015; Desidério et al. 2017). Souza et al. (2013a) recorded the occurrence of the species in the Caatinga domain, Amaraji municipality, Pernambuco state (altitude 320 m). This study provides the first record of species in Brejo de Altitude.
