Different kinds of constitutive heterochromatin variation were observed in 72 specimens of Cebus apella, belonging to five distinct subspecies, captured in four geographic regions of South America. One particular chromosome type, affecting pair 19, was found to be exclusive of one subspecies (Cebus apella paraguayanus) and to have a distribution significantly different from that expected at equilibrium. Conversely, some other chromosome polymorphisms were more widespread, with distributions compatible with equilibrium. Other variant types, probably resulting from paracentric inversions involving both heterochromatin and euchromatin, were rarer and restricted to single specimens. Finally, a distinctive chromosome type 11 was found to be exclusive of one subspecies (Cebus apella xanthosternos), where it appeared as a fixed trait.

“…The taxonomy of Neotropical primates has changed considerably in the past few years, reflecting current research efforts focusing on the group across the South American continent. Although Paraguayan specimens have been used in regional studies including morphology (Arístide et al 2014), genetics (Matayoshi et al 1986;Mudry et al 1987;Pargament and Slavutsky 1987;Martínez et al 2004;Mudry et al 2007;Casado et al 2010), phylogenetics and phylogeography (Hoyos et al 2016), ecology (Boyle 2014) and zoonosis (Díaz et al 2007), little research has been done on this group within Paraguay; the few works available focus on rare or uncommon species such as Mico melanurus (Stallings and Mittermeier 1983), Aotus azarae , and on the more common Alouatta caraya (Giordano and Ballard 2010). Conservation status of primates in Paraguay was assessed by Stallings (1985) and Rumiz and Stallings (1989) and has not been revised since.…”

As the center of convergence of some of the major bioregions of South America, Paraguay is a biodiverse country of biogeographic importance. Yet despite a long history of natural history research, basic knowledge of its fauna, including mammals, is still lacking. The last updated list of Paraguayan mammals was published in 2002, but increased research efforts since that time have brought about numerous changes in the taxonomy and known distribution of many species. We present an updated and annotated checklist on the mammals of Paraguay through 2016. Only species records based on the assessment of some type of verifiable voucher are included here. Because the Paraguay River has been considered a significant biogeographic boundary, the distribution of each species (east of the river, west of the river, present on both sides) is tabulated as well. We recorded 181 native species of mammals, 30 more than in 2002, belonging to 10 orders, 33 families, and 116 genera. Chiroptera (58) was the most diverse order, followed by Rodentia (56), Carnivora (20) and Didelphimorphia (18). Ctenomys pilarensis, C. paraguayensis y C. dorsalis are known only from Paraguay. The inventory is likely incomplete, as well as our knowledge of species distributional limits. Continued collecting of tissues and vouchers, as well as an examination of museum specimens, is necessary to address numerous unsolved questions concerning distribution, taxonomy, ecology, biogeography, population biology and the effects of anthropogenic modification.Paraguay, localizado en el centro sur de América del Sur, incluye dentro de sus límites algunas de las grandes ecorregiones del continente. A pesar de una larga historia de investigación mastozoológica, el conocimiento básico sobre los mamíferos de Paraguay es aún escaso. El último listado actualizado de especies se publicó en 2002; a partir de entonces se han realizado numerosos cambios taxonómicos y ajustes distribucionales. En este trabajo se presenta una lista de los mamíferos nativos de Paraguay actualizada a 2016 con base en investigación bibliográfica. Sólo se incluyeron en la lista especies nativas cuya ocurrencia en Paraguay fuese respaldada por la evaluación de algun voucher verificable. Dado que el río Paraguay se ha considerado un límite biogeográfico relevante (oriente y occidente del Paraguay), se registró la ocurrencia de las especies en cada una de estas regiones. Se contabilizaron 181 especies nativas (30 más que en 2002) pertenecientes a 10 órdenes, 33 familias y 116 géneros. Chiroptera (58) fue el orden más diverso, seguido por Rodentia (56), Carnivora (20) y Didelphimorphia (18). Ctenomys pilarensis, C. paraguayensis y C. dorsalis se conocen sólo de Paraguay. El inventario es probablemente aún incompleto, así como las distribuciones de muchas especies son todavía inciertas. Es preciso continuar con la colecta en campo de ejemplares y tejidos, así como el estudio de colecciones de museo, con el fin de abordar vacios de conocimiento sobre distribución, taxonomía, ecología, biogeografía y el ...

“…The G-and Q-banding patterns proposed [6] were based on a sample of 40 specimens of C. a. paraguayanus, which is considered [4] to be a subpopulation of the subspecies C. a. libidinosus. According to this banding pattern, all animals have a diploid number of 54 chromosomes, with 10 pairs of metacentrics and 16 pairs of acrocentrics making up the complement of autosomes.…”
