Discussion: Patton and Emmons (1985) recognized 2 subspecies ( bistriata and orinoci) and synonymized villosus in I. b. bistriata . Listed as bistriatus by Corbet and Hill (1991:206). The sequence analyses of da Silva and Patton (1993) and Patton et al. (2000) identified two geographic and taxonomic forms within bistriata . Bonvicino et al. (2003 a) recognized these two forms as distinct species, bistriata and negrensis . The karyotype has 2n=60, FN=116-118 ( Leal-Mesquita, 1991; Patton et al., 2000).
