Description

From Patton et al. (2007): "A small-bodied woodrat restricted to the deserts of western Arizona and northwestern Sonora. Tail proportionately long (86% of head-and-body length) but with number of caudal vertebrae averaging 25.5 and not significantly different from that found in N. lepida (F(1,55) = 0.076, p = 0.784). Pelage soft and silky; overall color tones intermediate with melanic individuals and/or populations known at various localities throughout range."
