“…About this statement, three assumptions were made here: (1) The record from Paraguay was cited by de la Sancha et al (2009) as a probable reference to J. pictipes. These authors mention that no voucher specimen can be associated to Santissima Trinidad, leaving uncertainty about its real identity.…”

“…The 151 species reported by Myers et al (2002); sent to publication in 1997) increased to 167 in the list by Neris (1998), and to 181 in this account, an increase of 19.9 % from Myers et al (2002) in less than 20 years. Species have been added due to new findings in the field, review of museum material, taxonomic revisions, and phylogenetic analyses (e. g., López-González et al 1998;Willig et al 2000;Voss et al 2005López-González 2005;Weksler and Bonvincino 2005;de la Sancha et al 2007;D'Elía et al 2008aD'Elía et al , 2008bPercequillo et al 2008;de la Sancha et al 2009;Stevens et al 2010;de la Sancha et al 2011;Bornholdt et al 2013;González-Ittig et al 2014;Moratelli and Wilson 2013;Owen et al 2014;de la Sancha and D'Elía 2015;Moratelli et al 2015;Timm et al 2015;Pardiñas et al 2016). The number of nomenclatural and taxonomic changes observed reflects an improving understanding of the diversity and phylogenetic relationships of the South American mammalian fauna in general, and the Paraguayan assemblage in particular.…”

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 history of mammalogy is among the earliest of South America with mammalian records as early as 1550 to 1770 by the Jesuit missionaries of the region (López-González et al, 2014). However, the mammalian fauna of Paraguay is still among the least studied and understood in the continent (Myers et al, 2002;López-González et al, 2014) as indicated by the number of recent new and noteworthy records from this country (de la Sancha et al, 2007(de la Sancha et al, , 2009(de la Sancha et al, , 2011D'Elía et al, 2008;de la Sancha & D'Elía, 2015; among others) many of which reflect new recent collections.…”

Paraguay is a small landlocked country whose mammalian fauna is among the least studied in South America, as well as their parasites. As a result of a study of the effects of habitat fragmentation on small mammal biodiversity in eastern Paraguay, we have collected some parasites of cricetid rodents. Herein, we describe a new species of Litomosoides Chandler, 1931 parasitising the body cavity of the tuft-toed rice rat Sooretamys angouya (Fischer) and Litomosoides esslingeri Bain, Petit & Diagne, 1989 parasitising Oligoryzomys nigripes (Olfers), thus expanding its geographical distribution into Paraguay. Litomosoides ysoguazu n. sp. is characterised by the large size of the females (92.2-117.6 mm long) and by having buccal capsule with an anterior widening with rounded edges on the chitinous segment and a rounded widening at the base; male tail with a single pair of adcloacal papillae, three to five pairs of asymmetrical postcloacal papillae, and one or two unpaired papillae in the median ventral line; spicules corresponding to the "sigmodontis" species group; and microfilaria with a sheath stuck to the body and visible in the anterior extremity. We also describe a fourth-stage female larva. Oligoryzomys nigripes is a new host record of L. esslingeri; this enlarges the host record to eight species highlighting the low specificity of this species.
