Reithrodontomys wagneri Hooper, 1950

Type locality. “ México, Michoacán, about 10 miles northwest of Ciudad Hidalgo, western flanks of Cerro San Andrés , 9400 feet elevation” .

Synonym. Reithrodontomys microdon wagneri ( Hooper 1950:169) . Type locality: see above.

Distribution. The Neovolcanic Belt in Mexico, with records in Michoacán, Ciudad de México, Estado de México, Morelos

and Guerrero, Mexico ( Hooper 1952; Hall 1981; González-Cózatl and Arellano 2015).

Remarks. We recommend inclusion within this species of the two populations from Guerrero, Mexico, recognized as Reithrodontomys bakeri , which according to the Principle of Priority (Article 23; ICZN 1999) should be renamed as R. wagneri . Also, we suggest the recognition of two subspecies within R. wagneri : R. w. wagneri and R. w. bakeri . For additional information on type material, cranial measurements, morphological and habitat characteristics, see Hooper (1952: 170).

Finally, haplogroup I should be considered as a candidate for a new species, with a known geographic distribution in the north of Sierra Madre Oriental (Tamaulipas and San Luis Potosí, Mexico) and Sierra de Otontepec (Veracruz, Mexico). This new species candidate represents the northernmost distribution known within the R. tenuirostris species group, increasing its distribution range to the mountainous regions of northeastern Mexico. Additional information sources (together with the already existing genetic information) such as morphological and ecological, among others, still are necessary to undertake the formal description of this candidate new species.
