Comments. The genus Stilestrongylus was defined by having a markedly asymmetrical caudal bursa, a hypertrophied genital cone and a synlophe with more than 24 cuticular ridges, small and subequal in size ( Notarnicola et al. 2010). Among the 26 species of Stilestrongylus described to date, 25 have been described from Sigmodontinae rodents and 1from a spiny rat ( Echimyidae ) ( Souza et al. 2009; Simões et al. 2014).

Some of the specimens found in T. nigrita in the present study were identified as a new species, differing from those previously described in this genus because of a particular combination of characters, including strong dissymmetry of the bursa, hypertrophy of the common trunk of right rays 2-6, length of dorsal ray and length of the spicules (unpublished data).
