| Sumario: | The monotypic status of Peromyscus furvus, an endemic species of deer mouse in Mexico, which includes P. latirostris and P. angustirostris in synonymy, is analyzed throughout its geographical range, along the Sierra Madre Oriental, the Mexican Transvolcanic Belt, and the Sierra Norte of Oaxaca, by using molecular (mitochondrial gene sequences of Cytochrome-b, ND3-ND4L-ND4), size (18 linear measurements of skull and five centroid sizes), and shape (five cranioventral morphogeometric configurations) characters. The respective simple gene phylogenies, together with genetic diversity and distance analyses, as well as haplotype networks, corroborated the genetic identity of five discrete geographic groups within P. furvus. Likewise, the respective simple phylogenies for cranial size and shape, allowed to test the behavior of continuous data without or with transformations to discretize them, and validated them as systematic characters, unveiling their corresponding evolutionary patterns. By integrating the characters by type (all genes; size and shape) or as a whole (all characters) in multicharacter phylogenies, it was confirmed that P. furvus should be considered sensu lato. In brief: a) P. latirostris (San Luís Potosí and Querétaro) resumes its level as a species. P. furvus becomes polytypic with P. f. angustirostris in Hidalgo, Puebla and Veracruz, as well as with P. f. furvus in Xalapa and its surroundings, Veracruz; c) a species novo from Puerto de la Soledad, Oaxaca is discovered; d) the situation, as a species, of the populations from La Esperanza, Oaxaca, remains pending. The habitats of all these species, which constitute and clarify the situation of the furvus Group within the Genus Peromyscus, corroborates their identity and allow to update their conservation status. |
