... The species uses both forested and open areas but prefers forested habitats (5,12). This is a poorly known species of armadillo, with relatively few records in Brazilian museums (13). In the IUCN Red List, it is listed as the least concern (12), whereas in the Brazilian Red Book, it is considered data deficient (14). ...
... Spicules slightly dissimilar, left spicule 134 (126-146) and right spicule 144 (134-160) long ( Figures 1G, 3C). Gubernaculum present 36 (29-45) long and 16 (12)(13)(14)(15)(16)(17)(18)(19) wide ( Figure 3F). Etymology: The species epithet is due to the specific name of the host. ...
A new species of nematode parasite of the genus Delicata (Molineidae: Anoplostrongylinae) is described from the small intestine of a road-killed Greater Naked-tailed Armadillo Cabassous tatouay (Cingulata: Chlamyphoridae) on the BR-040 highway in Rio de Janeiro state, Brazil. The genus Delicata includes 13 species of parasitizing armadillos and anteaters distributed in Brazil, Argentina, and Trinidad and Tobago. The present species is distinguished from almost all species of Delicata by the longest length of the body, except for D. khalili and D. appendiculata. However, these can be distinguished from each other by the length of the spicules. The species that closely resembles, Delicata tatouay n. sp. is D. speciosa, but it can be distinguished by a robust branch from rays 2 and 3, rays 4 larger, and rays 8 longer compared to those of the new species. The new species is the only one with a tail, characterized by a terminal spine with rattlesnake tail-like transversal striations.
... Cingulata of the genera Dasypus and Cabassous are common in the Brazilian territory, including the Ribeira de Iguape Valley (Wetzel, 1980;Anacleto et al., 2014;Gonzalez & Abba, 2014;Hayssen, 2014b;Chahud et al., 2021). The genus Cabassous can be found in very diverse environmental settings, while Dasypus is common in forests, also occurring in drier environments (Ubaid et al., 2010;Feijó & Cordeiro Estrela, 2016;Feijó et al., 2018). Both genera can be sympatric and, given the diversity of environments where they can be found, it is not possible to determine the paleoenvironment only by the presence of these genera. ...
The Ribeira de Iguape Valley, located in southeastern Brazil, is an important karstic region, presenting a large number of caves containing fossil and subfossil vertebrate materials. The Abismo Ponta de Flecha Cave is a complex vertical cave divided into galleries where a large amount of osteological material was collected. The cave acted as a natural trap for several taxa and possibly as a disposal site for ancient human communities. Osteoderms and appendicular bones assigned to two genera of Cingulata were identified in the faunal assemblage. The most abundant bone material belongs to the family Chlamyphoridae, genus Cabassous, represented by the living species C. tatouay and by remains of a larger, but little-known species, cf. C. antiquus. The other identified genus belongs to the family Dasypodidae: Dasypus sp. Evidence of human activity was characterized in only one C. tatouay bone, while the other specimens were considered as being of natural origin. Keywords: Quaternary, Chlamyphoridae, Dasypus, Cabassous, taxonomy.
... The incertitude of the distribution of C. tatouay relates to the biology of the species, which is fossorial, mainly nocturnal and solitary, and probably occurs in low densities (Meritt 1985;Anacleto et al. 2014). Also, C. tatouay has few specimens housed in scientific collections, poorly detailed records, and rare visualizations in the field (Wetzel 1980;Eisenberg & Redford 1999;Anacleto et al. 2006;Ubaid et al. 2010). Accordingly, several authors acknowledge the necessity of further biogeographic studies on this armadillo (Oliveira & Vilella 2003;Ubaid et al. 2010;Gonzalez & Abba 2014). ...

In this sense, species distribution models (SDM) can be especially useful to determine the geographic range of elusive taxa, such as C. tatouay. ...
... Although poaching and retaliation impact the species (Oliveira et al. 2015), the main threat for C. tatouay is the extensive habitat loss (Ubaid et al. 2010), especially along the Cerrado and Atlantic Forest, biomes that account for most of its distribution (Anacleto et al. 2014;Feijó & Anacleto 2021). The species is found in secondary habitats but absent in intensely disturbed locations (Feijó & Anacleto 2021). ...
Cabassous tatouay occurs in moist forests, savannas, and grasslands of south, central, and northeastern Brazil, eastern Paraguay, northeastern Argentina, and Uruguay. Despite its wide distribution range, C. tatouay is scarcely recorded in some regions. This study aimed to: present new records of C. tatouay; compile the localities where the species was recorded according to published scientific accounts; and model its distribution range along South America. We present five new records of C. tatouay from Goiás and Minas Gerais states, Brazil. The review of published accounts resulted in 99 studies, which provided 279 occurrences of C. tatouay to Brazil, Argentina, Paraguay, and Uruguay. The great majority of records are from Brazil, mainly from the Atlantic Forest (119), Cerrado (52), and Pampas (49) biomes. Most records from the Cerrado are placed close to or in transition zones with the Atlantic Forest. Five records are within the Caatinga, but restricted to humid montane forest enclaves. The species distribution models indicate that C. tatouay is probably absent to Amazonia and Pantanal. The higher suitability for the species occurs in eastern Paraguay, northeastern Argentina, and south central Brazil, specifically in the Pampas, Atlantic Forest, and the southern part of the Cerrado.
... No Brasil, a avaliação de risco nacional considera essa espécie com 'dados insuficientes' (DD) para definição de seu estado de ameaça . No entanto, C. tatouay está presente em seis listas estaduais oficiais de fauna ameaçada de extinção no Brasil, sendo classificada nas categorias 'dados insuficientes' (Espírito Santo, São Paulo, Paraná, Rio Grande do Sul), 'presumivelmente ameaçada' (Rio de Janeiro) e 'quase ameaçada' (Minas Gerais; Ubaid et al., 2010;Anacleto et al., 2015a). ...
Xenarthra contém duas ordens, seis famílias, 14 gêneros e 38 espécies viventes. A ordem Cingulata (tatus) representa 22 das espécies de xenartros e seis destas são encontradas no Pantanal (Dasypus novemcinctus, Cabassous tatouay, C. squamicaudis, Tolypeutes matacus, Euphractus sexcinctus e Priodontes maximus). Os tatus se diferem de outros mamíferos por terem uma carapaça formada por placas ósseas articuladas que, como um escudo, cobrem a cabeça e o dorso. Neste artigo, baseamo-nos em extensa revisão bibliográfica e décadas de trabalho realizado pelos autores para descrever o estado do conhecimento sobre ecologia, biologia, características morfológicas, saúde, estado de conservação e distribuição dos tatus no Pantanal. Visando dar subsídios a futuros trabalhos com as espécies, também descrevemos melhores práticas para a captura e o manejo (e.g., anestesia e coleta de material biológico) das espécies em campo. Apesar do recente aumento do número de estudos, ainda restam diversas lacunas de informação sobre a ecologia e a biologia da maioria das espécies de tatus do Pantanal. Sendo assim, esperamos que as informações e os métodos descritos aqui sirvam de estímulo e base para o desenvolvimento de novos estudos, que aumentem nosso conhecimento sobre estas espécies na região do Pantanal e permitam o planejamento de estratégias de conservação eficientes.
... This species co-occurs with Cabassous tatouay in Goiás Sanderson & Silveira, 2003;Rocha et al. 2019) and, as well as for other species of armadillos, the number of records varied between studies, depending on the type of habitat, and the degree of conservation of surveyed areas. Tolypeutes tricinctus and C. tatouay were the rarest species throughout its range in Cerrado, including Goiás (Anacleto et al. 2006;Ubaid et al. 2010). ...
The state of Goiás, in central Brazil, is covered mainly by the Cerrado domain, with the Alto Paraná Atlantic Forest occupying its central-southern portion. Goiás is one of the 20 Brazilian federative units without a mammal checklist. In this study, we provide the first checklist of mammals from Goiás state. We recorded mammal species based primarily on the analysis of specimens housed in scientific collections as well as on literature with associated voucher material. We listed 191 mammalian species belonging to 125 genera, 31 families and 10 orders, which represents 25.2% of the mammal species occurring in Brazil. The most speciose orders were Chiroptera (90 spp.), followed by Rodentia (43 spp.), Carnivora (19 spp.) and Didelphimorphia (17 spp.). The following orders accounted for a smaller portion of the state diversity: Cetartiodactyla (7 spp.), Cingulata (7 spp.), Primates (4 spp.), Pilosa (2 spp.), Lagomorpha (1 sp.), and Perissodactyla (1 sp.). A total of 28 species (14.7%), mainly represented by medium and large-sized mammals, are nationally threatened while 12 (6.3%) are globally threatened. Our results indicate great portions of the state lacking a proper survey of mammals, especially the northwestern portion. We discuss species richness, distribution and conservation status of the mammals of Goiás state in national and regional scenarios. We highlight the need for mammal inventories based on complementary survey techniques with the collection of vouchers in order to provide karyologic, molecular, morphologic, parasitologic, and ecological data. These informations are the basis for integrative studies that lead to the understanding of current mammalian richness and diversity. Indeed, knowledge on species richness distribution in the state will guide conservation strategies, especially in areas undergoing habitat loss and fragmentation, such as the central-southern portion of Goiás. © 2021, Universidade Estadual de Campinas UNICAMP.

... There is a lack of data concerning its range in northeastern Brazil, with a few records in the state of Bahia (Pereira & Geise 2009;Ribeiro et al. 2013) and five specimens in university collections which are from the states of Paraíba, Pernambuco and Ceará (Feijó & Langguth 2013). Several records of C. tatouay were reported by Ubaid et al. (2010) in the western region of the state of São Paulo, Brazil. Oliveira et al. (2015) report the occurrence of C. tatouay in Rio Grande do Sul state, Brazil. ...
During a study to characterize the medium and large-sized mammal community of the Tijuca National Park (3953 ha; Rio de Janeiro state), we registered for the first time the naked-tailed armadillo (Cabassous sp.). From April to September 2016, 42 camera-traps were set in the area, resulting in a total effort of 4302 trap-days. From the 1434 independent records obtained, five were of Cabassous sp. Two species of naked-tailed armadillo occur in Brazil, C. tatouay and C. unicinctus. Both of their distribution limits are uncertain and Cabassous C. tatouay is considered data deficient. Unfortunately, it was not possible to identify precisely the species.
... Species of the genus Cabassous have been reported to have both nocturnal and diurnal activity. Cabassous tatouay has been recorded active during the daytime in the Cerrado of Mato Grosso do Sul (Massocato and Desbiez, 2017), but also in the late afternoon and early evening elsewhere (Ubaid et al., 2010). In contrast, C. chacoensis has only been reported to be active in the middle of the day (Monguillot and Miatello, 2009;Tamburini and Briguera, 2012). ...
The natural history of the southern naked-tailed armadillo Cabassous unicinctus squamicaudis is not well known. Here, we provide basic information about burrow systems, home ranges, activity, morphometric measures, and reproductive behaviour. We monitored 10 individuals through VHF telemetry and direct observations in the central Pantanal of Brazil for 24 months. Males (2.06 km²) had significantly larger home ranges than females (0.59 km²) and home ranges of males overlapped with those of several females. There was very little overlap in ranges of the same sex and very few social interactions were observed. Southern naked-tailed armadillos dug convoluted galleries to forage, and, unless they used their entrance to exit, they emerged on average 2 m away (ranging from 0.01 m to 17 m) from the burrow entrance. When leaving their burrows, they spend on average 6.5 min above ground, travelling an average of 83 m (ranging from 1 m to 781 m) before going back underground. They do not return to sleep in a particular burrow, changing burrows frequently. The studied armadillos were diurnal, and spend 99.25% of the day underground, emerging only during the hottest period of the day (mid-afternoon). The southern naked-tailed armadillos should be classified as a subterranean species, rather than fossorial since they spent most of their time underground where foraging also takes place. Minimum densities of C. u. squamicaudis were estimated at 2.21 adults/km². Gestation was estimated to last for 4 months. Parental care of a single young lasted on average 4 months. Niche overlap between E. sexcinctus and C. u. squamicaudis in the study area is minimal.
... In Brazil, it has been recorded in the Atlantic Forest, Cerrado, Pantanal, and the Pampas (Anacleto et al., 2006;Paglia et al., 2012). Its ecology and biology are poorly known (Ubaid et al., 2010). Species occurrence records are rare (e.g., Cherem et al., 2004;Modesto et al., 2008;Pereira & Geise, 2009;Ubaid et al., 2010;Ribeiro et al., 2013) and there are few specimens in scientific collections (Ubaid et al., 2010). ...

The Pampas comprise the southern boundary of Cabassous tatouay distribution, where it is thought to be rare. Here I modeled the species distribution in the Brazilian and Uruguayan Pampas to assess the proportion of vegetation remnants climatically suitable for the species and to indicate priority areas for biological sampling to find unknown populations. Results showed that climatically suitable areas for C. tatouay are not continuous over the Pampas and there are three main core areas, being 73% of its predicted distribution located in the Brazilian Pampas and only 27% in the Uruguayan Pampas. In Brazil, the proportion of climatically suitable habitat is 44%, being 56% lost to human activities. Predicted distribution of C. tatouay within protected areas in the Pampas represents only 6.1% of the whole predicted area and priority areas to the occurrence of unknown populations of C. tatouay are indicated. The species conservation in the Pampas is concerning because most of its records are outside protected areas and there is no information on population situation and no updated surveys confirming species persistence in areas of old occurrence data. I hope these suggestions will serve as a guideline to focus future conservation assessments for the species.

... The lack of physical records of these two armadillos in national scientific collections, and their infrequent appearance on local inventories, limit detailed studies on their taxonomy, phylogeny, geographical distribution, and conservation status (Fonseca et al., 1996; Nowak, 1999; Anacleto et al., 2006). That Cabassous tatouay, greater naked-tailed armadillo, is a poorly known species has been reported by Wetzel (1982), Redford (1985), Ubaid et al. (2010), Gonzales & Lanfranco (2010) and Hayssen (2014). The southernmost records of the species are from the Uruguayan provinces of Maldonado and Lavalleja (Coitiño et al., 2013). ...
Cabassous tatouay Desmarest, 1804 é considerada espécie rara no sul da América do Sul, apresentando registros escassos e imprecisos para o Rio Grande do Sul. O presente estudo descreve 40 localidades de ocorrência de C. tatouay e apresenta de um mapa de distribuição geográfica potencial, gerado por Modelagem Ecológica de Nicho. A modelagem de nicho sugere uma associação da espécie com áreas de matriz campestre, incluindo o Pampa e os Campos de Cima da Serra, associados à Mata Atlântica. Este estudo contribui para o melhor conhecimento do tatu-de-rabo-mole no Sul do Brasil e fornece dados-chave para sua conservação.
