“…Wiedomys cerradensis is endemic to the Cerrado, and has been recorded in the Brazilian states of Bahia, Ceará, Goiás, and Tocantins (Gonçalves et al 2005, Bezerra et al 2013, Bonvicino 2015, Gurgel-Filho et al 2015). Gurgel-Filho et al (2015) indicated that the species also occurs in the Brazilian states of Piauí, Maranhão, Paraíba, and Pernambuco, but did not provide evidence supporting this assertion.…”

“…In absence of a comprehensive systematic review for the genus Thrichomys , we provisionally adhere to that synthesis, according to which Thrichomys apereoides is restricted to a few localities in the state of Minas Gerais. Nevertheless, records potentially attributable to this species exist for localities corresponding to the Cerrado biome in the Brazilian states of Goiás and Tocantins (Bezerra et al 2013, Gomes et al 2015). Clearly, a systematic review including karyotyped and sequenced samples from throughout the distribution of all currently recognized species and their type localities is needed to establish species boundaries and distributions.…”

Citation: Gutiérrez EE, Marinho-Filho J (2017) The mammalian faunas endemic to the Cerrado and the Caatinga. ZooKeys 644: 105-157. https://doi.org/10.3897/zookeys.644.10827 AbstractWe undertook a comprehensive, critical review of literature concerning the distribution, conservation status, and taxonomy of species of mammals endemic to the Cerrado and the Caatinga, the two largest biomes of the South American Dry-Diagonal. We present species accounts and lists of species, which we built with criteria that, in our opinion, yielded results with increased scientific rigor relative to previously published lists -e.g., excluding nominal taxa whose statuses as species have been claimed only on the basis of unpublished data, incomplete taxonomic work, or weak evidence. For various taxa, we provided arguments regarding species distributions, conservation and taxonomic statuses previously lacking in the literature. Two major findings are worth highlighting. First, we unveil the existence of a group of species endemic to both the Cerrado and the Caatinga (i.e., present in both biomes and absent in all other biomes). From the biogeographic point of view, this group, herein referred to as Caatinga-Cerrado endemics, deserves attention as a unit -just as in case of the Caatinga-only and the Cerrado-only endemics. We present preliminary hypotheses on the origin of these three endemic faunas (Cerrado-only, Caatingaonly, and Caatinga-Cerrado endemics). Secondly, we discovered that a substantial portion of the endemic mammalian faunas of the Caatinga and the Cerrado faces risks of extinction that are unrecognized in the highly influential Red List of Threatened Species published by the International Union for Conservation of Nature (IUCN). "Data deficient" is a category that misrepresents the real risks of extinction of these species considering that (a) some of these species are known only from a handful of specimens collected in a single or a few localities long ago; (b) the Cerrado and the Caatinga have been sufficiently sampled to guarantee collection of additional specimens of these species if they were abundant; (c) natural habitats RESEARCH ARTICLE Launched to accelerate biodiversity research A peer-reviewed open-access journalEliécer E. Gutiérrez & Jader Marinho-Filho / ZooKeys 644: 105-157 (2017) 106 of the Cerrado and the Caatinga have been substantially altered or lost in recent decades. Failures either in the design of the IUCN criteria or in their application to assign categories of extinction risks represent an additional important threat to these endemic faunas because their real risks of extinctions become hidden. It is imperative to correct this situation, particularly considering that these species are associated to habitats that are experiencing fast transformation into areas for agriculture, at an unbearable cost for biodiversity.

“…There are no data on the diet, reproduction, or population structure of W. cerradensis , and the only information available on its natural history indicate that it is an arboreal species, found principally in semideciduous forest and Cerrado savanna ( Bezerra et al 2013 ). Bonvicino et al (2008) concluded that Wiedomys cerradensis is found only in the southwest of the state of Brought to you by | Northern Arizona University Authenticated Download Date | 5/31/15 3:47 AM Bahia, although Bezerra et al (2013) recently extended the distribution of the species 186 km west to the states of Tocantins and Goi á s. Gon ç alves et al (2003) considered Wiedomys to be a basal taxon of the subfamily Sigmodontinae, intimately related to other tribes, the diversity of which is still poorly understood. Little is known of W. cerradensis , and its geographic distribution has yet to be defined reliably.…”

Wiedomys cerradensis (Gon ç alves, Almeida, Bonvicino, 2003) (Rodentia, Cricetidae): first record from the state of Maranh ã o, Brazil Abstract : Wiedomys Hershkovitz, 1959, was considered to be a monotypic genus for > 40 years until P.R. Gon ç alves et al. described Wiedomys cerradensis from the Cerrado savannas of central Brazil. The geographic distribution of this arboreal species is not yet fully understood. The present study confirms the occurrence of the species in the Brazilian state of Maranh ã o. A male Wiedomys specimen was collected in the Inhamum Municipal Environmental Protection Area, which is dominated by Cerrado vegetation, although the species could not be identified from morphological characteristics alone. Molecular analyses were based on the mitochondrial cytochrome b gene. The cytochrome b sequences indicated low divergence between the Maranh ã o specimen and W. cerradensis , and much higher divergence from the specimens of Wiedomys pyrrhorhinus , with the two species being well defined according to the high bootstrap values obtained in the analysis. The molecular data nevertheless permitted the confirmation of the occurrence of W. cerradensis in Maranh ã o, the first record of the species in this state, at a location > 900 km from its previously known distribution.
