Alterosa falcata Blahnik (2005)

Although most species of the genus Alterosa have fairly restricted distributions in pristine Atlantic Forest streams, A. falcata Blahnik (2005) can be considered one of the few exceptions. Originally described from several locations in Minas Gerais, Rio de Janeiro and São Paulo states ( Blahnik, 2005), its distribution was extended to other areas of these states ( Dumas et al., 2009; Dumas & Nessimian, 2012). Herein, we record this species for the first time from Espírito Santo state, southeastern Brazil.
