Contreras-Moreno1, Daniel Thornton2,3, and Mircea G. Hidalgo-Mihart1,4 ABSTRACT.—The northern naked-tailed armadillo (Cabassous centralis ) is one of the least known armadillo species. Due to its restricted distribution in Mexico and the few known records of the species, the northern naked-tailed armadillo is considered endangered by Mexican law. Using camera traps, we obtained a new record in Portaceli, Chia- pas, an area where the species was not previously recorded. The record was located 75 km north of the previously known range of the species in Mexico, and thus constitutes a range expansion of the species in the country. This record suggests that the species could be present in areas with similar environmental conditions where mammal research has been limited, especially in Tabasco, Mexico, and in Sierra del Lacandón, Guatemala. It is necessary to generate additional information on the species in order to determine the current status of the northern naked-tailed armadillo in Mexico. RESUMEN.—El armadillo de cola desnuda (Cabassous centralis; ACD) es una especie de hábitos poco conocidos, considerada en peligro de extinción por las leyes mexicanas. El armadillo cola desnuda presenta una distribución restringida en México y se cuenta con pocos registros en el país. Utilizando cámaras trampa obtuvimos una fotografía de ACD en Portaceli, Chiapas, un área nueva para la especie al noreste de Chiapas. El registro del armadillo se localizó 75 km al norte del área de distribución conocida de la especie en México, lo que constituye una ampliación en el área de distribución de la especie. El registro implica que probablemente la especie se encuentra presente en áreas poco estudi- adas desde el punto de vista mastozoológico y ambientalmente similares localizadas en Guatemala y México, especial- mente en la región del Cañón del Usumacinta. Se debe incrementar la información del armadillo cola desnuda en México con el fin de determinar el estatus que presenta en el país.

  • (Dasypus) in North America Based on Ancient Mitochondrial DNA
    bs_bs_banner A revised evolutionary history of armadillos (Dasypus) in North America based on ancient mitochondrial DNA BETH SHAPIRO, RUSSELL W. GRAHAM AND BRANDON LETTS Shapiro, B. Graham, R. W. & Letts, B.: A revised evolutionary history of armadillos (Dasypus) in North America based on ancient mitochondrial DNA. Boreas. 10.1111/bor.12094. ISSN 0300-9483. The large, beautiful armadillo, Dasypus bellus, first appeared in North America about 2.5 million years ago, and was extinct across its southeastern US range by 11 thousand years ago (ka). Within the last 150 years, the much smaller nine-banded armadillo, D. novemcinctus, has expanded rapidly out of Mexico and colonized much of the former range of the beautiful armadillo. The high degree of morphological similarity between these two species has led to speculation that they might be a single, highly adaptable species with phenotypical responses and geographical range fluctuations resulting from environmental changes. If this is correct, then the biology and tolerance limits for D. novemcinctus could be directly applied to the Pleistocene species, D. bellus. To investigate this, we isolated ancient mitochondrial DNA from late Pleistocene-age specimens of Dasypus from Missouri and Florida. We identified two genetically distinct mitochondrial lineages, which most likely correspond to D. bellus (Missouri) and D. novemcinctus (Florida). Surprisingly, both lineages were isolated from large specimens that were identified previously as D. bellus. Our results suggest that D. novemcinctus, which is currently classified as an invasive species, was already present in central Florida around 10 ka, significantly earlier than previously believed.

  • The Conservation Game
    From Penguins to Pandas - the conservation game Armadillo Fact Files © RZSS 2014 Armadillos There are 21 species of armadillo. They are divided into 8 groups: dwarf fairy giant hairy long nosed naked tail three banded yellow banded All armadillos have an outer covering of strong bony plates and horny skin. Most of the species can bring their legs in under this covering to protect themselves but it is only the three banded armadillos that can roll up into a tight ball. Most are active at night (nocturnal) and have poor eyesight but very good hearing and sense of smell. They all have large claws on their front feet to dig for insects and for burrowing. There is little known about some species of armadillo. At the time of writing (May 2014), the Royal Zoological Society of Scotland (RZSS) are studying four species - giant, southern naked tail, nine banded and yellow banded. Edinburgh Zoo, owned by RZSS holds 2 species, the larger hairy and the southern three banded. These animals are not on show but are sometimes seen in our animal presentations, such as ‘Animal Antics’.

Yogui3,4, Mario Henrique Alves3,5, Danny Fuentes‑Castillo1, Catalina Ospina‑Pinto1, Roberta Ramblas Zamana1, Arnaud Leonard Jean Desbiez3,6 & Jose Luiz Catão‑Dias1 Knowledge of infectious diseases in wildlife provides important information for preventing potential outbreaks of zoonotic diseases. Adiaspiromycosis is a neglected human disease caused by dimorphic Onygenales fungi. The disease is produced by the infammatory response against growing adiaspores, leading to granulomatous pneumonia. In humans, adiaspiromycosis is relevant in immunosuppressed patients. In animals, it is associated with pneumonia in fossorial species. Given the potential role of armadillos in the epidemiology of adiaspiromycosis, in this study, we sought to investigate the occurrence and pathological features of adiaspiromycosis in roadkilled armadillos. In total, 54 armadillo carcasses were suitable for postmortem pathologic examinations between February 2017 and 2020. Adiaspores, associated with granulomatous lesions, were observed in ten six‑banded (Euphractus sexcinctus) and two southern naked‑tailed armadillos (Cabassous unicinctus). A previously uncharacterized Onygenales species was molecularly identifed in two E. sexcinctus. In summary, herein we report 12 cases of pulmonary adiaspiromycosis (PA) in two species of free‑ living armadillos in Brazil. Both, the morphology of the fungus, as well as the histopathological fndings (granulomatous infammatory response to adiaspores) are consistent with PA; however, as the molecular identifcation difers from the reported species, the potential impact of this fungus for human PA is unknown, and we cannot rule out its impact on public health.

    Smith P - Cabassous unicinctus - FAUNA Paraguay Handbook of the Mammals of Paraguay Number 40 20011 SOUTHERN NAKED-TAILED ARMADILLO Cabassous unicinctus (Linnaeus, 1758) FIGURE 1 - Adult dorsal view. Estancia Pa´i Kuára, Departamento Amambay, January 2006. (Photo Hugo del Castillo). TAXONOMY: Class Mammalia; Subclass Theria; Infraclass Eutheria; Order Cingulata; Family Dasypodidae; Subfamily Tolypeutinae, Tribe Priodontini (Myers et al 2006). The genus Cabassous was defined by McMurtrie (1831) and contains four species, three of which are present in Paraguay. The genus was reviewed by Wetzel (1980). There are two quite distinct subspecies, one of which, C.u.squamicaudis , is present in Paraguay (Wetzel 1980). It is possible that these two subspecies in fact represent distinct species, with the divergence between them in morphology and other characters of taxonomic importance greater than or equal to differences between C.u.unicinctus and other species in many cases. Wetzel (1980) retained them as subspecies presumably on the basis of a reported zone of intergradation in the Amazon River area, though the intergradation of two closely related but distinct species in a zone of overlap may not be completely out of the question. The species name unicinctus means "single band" in Latin. The subspecies name squamicaudis means "scaly tail" presumably in reference to the increased presence of tail scutes when compared with the nominate subspecies. Xenurus squamicaudis (Lund 1843) was considered a fossil species upon its discovery in mixed material from caverns of Minas Gerais, and this arrangement was followed by Winge (1915) and Paula Couto (1950, 1973). Wetzel (1980) however found the material to be referable to this species.

Like all armadillos, it bears a carapace of ossified dermal scutes covered by epidermal scales. This diurnal species mainly inhabits grasslands on humic soils in Argentina, Uruguay, Paraguay, and southern Brazil. D. hybridus is omnivorous with a tendency to myrmecophagy and gives birth to 6–12 presumably genetically identical offspring. Listed as “Near Threatened” by the International Union for Conservation of Nature and Natural Resources, it is mainly threatened by habitat loss and hunting.

Abstract: We compared characteristics of a population of nine-banded armadillos (Dasypus novemcinctus) studied in the southern United States with a population found in the Atlantic coastal rainforest of Brazil. Adult armadillos in Brazil weighed less than those in the U.S., but when weight was accounted for, did not differ in other measures of body size. However, juveniles in the U.S. were proportionately bigger than those in Brazil. Armadillos in Brazil were less abundant (numbers sighted per h of observation) and were active later at night than those in the U.S. Adult sex-ratios were male-biased in both populations: Finally, there was no significant difference in the incidence of litterrnate associations observed in the two populations, but groups of juveniles (which included non-litterrnates) were observed more frequently in the U.S. Many of these differences may be due to the fact that armadillos are hunted extensively in Brazil but not in the United States.
