Comments. The morphological characters observed in the specimens agree with the original description and subsequent redescriptions given by Travassos (1937) and Robles & Navone (2010), i.e. presence of cervical and lateral alae and the absence of deirids in both sexes, equidistant mamelons, accessory hook of the gubernaculum very small and without ornamentation, and relatively long tail in males, among other morphometric features.

The species was described for N. squamipes from Angra dos Reis, Rio de Janeiro Brazil. Quentin (1969) redescribed the species based on specimens from Melanomys caliginosus (Tomes 1860) ( Sigmodontinae, Orizomyini ) in Valle del Cauca, Colombia. Robles & Navone (2010) redescribed S. venteli based on the type specimens and other records of N. squamipes from Balneario Municipal de Aristóbulo del Valle in the stream Cuña Pirú and Puerto Península, Misiones province. In addition, Gomes & Vicente (1984) and Gomes et al. (2003) recorded this species for N. squamipes from different localities of Rio de Janeiro, Brazil.
