Eligmodontia moreni Thomas, 1896 . Ann. Mag. Nat. Hist., ser. 6, 18:307.

TYPE LOCALITY: Argentina, La Rioja Prov., Chilecito, 1200 m .

DISTRIBUTION: Atlantic-facing Andean slopes at intermediate elevations. El Salta to Neuquen Prov., NW Argentina; limits poorly documented.

COMMENTS: Mares et al. (1981 b, 1989b) noted the morphological, distributional, and ecological distinction of E. moreni and E. puerulus in El Salta Prov., Argentina. The differentiation of moreni from morgani in the S Andes and from typus in the Pampas warrants further study.
