Author: | Wagner, 1845. | Citation: | Arch. Naturgesch., 1: 146. | Common Name: | Yellow-crowned Brush-tailed Rat | Type Locality: | Brazil, Mato Grosso, Río Guaporé. | Distribution: | E Bolivia and E Peru, SW to NC Brazil, S Venezuela, adjacent Colombia. | Status: | IUCN – Lower Risk (nt). | Comments: | 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. (2003a) 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). |
