“…Thylamys karimii is endemic to the Cerrado and the Caatinga, and has been recorded in the Brazilian states of Bahia, Goiás, Mato Grosso, Minas Gerais, Pernambuco, Piauí, Rondônia, Sergipe, and Tocantins, and in the Distrito Federal (Carmignotto and Monfort 2006, Carvalho et al 2009, Bruna et al 2010, Carmignotto and Aires 2011, Bonvicino et al 2012, Bezerra et al 2014). The species has not been reported for Bolivia, but its presence on the Serranía de Huanchaca in the Santa Cruz department of that country might be expected (Giarla et al 2010).…”

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published lists -e.g., excluding nominal taxa whose statuses as species have been claimed only on the basis of unpublished data, incomplete taxonomic work, or weak evidence.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.

“…Of these, only three are sufficiently explicit to merit statistical testing: (1) Palma et al (2002) analyzed cytochrome-b sequence data from five species of Thylamys and recovered the topology (macrurus (pusillus (venustus (elegans + pallidior)))), (2) Braun et al (2005) analyzed cytochrome-b sequence data from seven species and recovered the topology (macrurus ((venustus + sponsorius) (pusillus (pallidior (elegans + tatei))))), and (3) Carvalho et al (2009) analyzed cytochrome-b sequence data from eight species and recovered the topology (macrurus ((sponsorius + venustus) (karimii (pusillus (pallidior (tatei + elegans)))))). All of these hypotheses can be confidently rejected using Shimodaira and Hasegawa's (1999) likelihood-ratio test with our combined-gene data (P 5 0.00 for all alternatives).…”

“…The second is AF431927, said to have been obtained from a Bolivian specimen of T. pusillus (NK 25139). Both sequences were originally obtained and analyzed by Palma et al (2002), but Braun et al (2005) and Carvalho et al (2009) subsequently used AF431926 (downloaded from GenBank) in their analyses. Because we independently extracted and amplified cytochrome b from NK 27536 (T. macrurus) and NK 25139 (T. pusillus), we were able to compare our sequences with those obtained by Palma et al (2002).…”

“…A recent revision of marsupials from the Neotropics considered T. sponsorius as a valid species based on information available on morphology (Gardner 2007). More recently, another molecular study that included T. karimii from the Brazilian Caatinga and Cerrado recovered the latter as basal to a clade that joined T. pusillus (T. elegans-T. pallidior) (Carvalho et al 2009).…”

Molecular phylogenetics of mouse opossums: new findings on the phylogeny of Thylamys (Didelphimorphia, Didelphidae)

et al. 2014

The mouse opossums of the genus Thylamys constitute a group of species mainly adapted to open xeric‐like habitats and restricted to the southern portion of South America. We used molecular data (mitochondrial and nuclear sequences) to evaluate the phylogenetic and biogeographical relationships of all currently known living species of the genus, recognizing a new taxon from the middle and high elevations of the Peruvian Andes and evaluating the phylogenetic structuring within T. pallidior and T. elegans, as well as the validity of T. sponsorius, T. cinderella and T. tatei, and the haplogroups recognized within T. pusillus. Our results confirm the monophyly of the genus and that the Caatinga and the Cerrado inhabitants Thylamys karimii and T. velutinus are the most basal species in the radiation of Thylamys. We also calibrated a molecular clock which hypothesized a time of origin of the genus of about 24 My, with most species differentiating in middle and late Miocene and Plio‐Pleistocene times of South America.
