Comments. The morphological characters observed in the specimens agree with the original description given by Quentin (1968), i.e. absence of deirids in both sexes, well-developed cervical alae in females, equidistant mamelons, accessory hook of gubernaculum with ornamentation on whole surface, relatively long tail in males, among other morphometric features.

This species was originally described by Quentin (1968) for N. lasiurus and recorded for O. nigripes and Sigmodontomys alfari (Allen 1897) ( Quentin 1968, 1969) from Pernambuco, Brazil. In Argentina, Robles (2010) mentions this species parasitizing T. nigrita from Balneario Municipal de Aristóbulo del Valle in the stream Cuña Pirú and Caraguatay, Misiones province, and N. lasiurus from Finca La Adelita, Laguna Paiva, Corrientes province; Colonia Villafañe, Formosa province; Estación Experimental del INTA Villa Miguel Lanús, Misiones province; Oliveros, Uranga and Maciel in Santa Fe province; and Pergamino and Rojas in Buenos Aires province.
