Morphological characters
The newly trapped specimens display the typical Otomys laminated tooth pattern. The females have 0 + 1 mammae. On the molars we observe the presence of five laminae on M/1, the deeply grooved incisors (one striation 1/1) and a 7-8 laminae pattern in the upper M3. But, based on their morphology and external measurements (Table 6), we assigned the new samples to the endemic O. occidentalis species. This was confirmed in a molecular and morphometrical revision of the 5 laminae species complex (Taylor et al. 2014).
