The original description was based on two specimens, an adult and a juvenile, from one locality in southern Bolivia (Tapecua, 1500 m, 21°26' S, 63°55' W, Department of Tarija). The second record for the species and first mention for Argentina was published recently by Barquez et al. (2006), based on a young specimen collected at "Finca Las Capillas, cercanías de Arroyo Los Matos y Ruta Provincial 20, 1200 m, 24º04' S, 65º08' O, Jujuy Province". This rare genus was known until now, from these two localities and three specimens. Here, we report a new record for the species in Argentina, also from Jujuy Province. The new

Two subspecies are recognized by the shape of the dorsal margin of the helmet, apical shape of the spines in helmet and genal combs, length of first and fourth segments of the maxillary palpus, and shape of the hilla of the spermatheca. The validity of the characters used to separate the 2 subspecies of Nonnapsylla rothschildi Wagner, 1938 is discussed based on information from the literature, as well as from direct observation of type specimens and specimens collected in northwestern Argentina. We conclude that Nonnapsylla rothschildi wagneri Johnson, 1957 should be considered as a synonym of the nominal subspecies. We also extend the southern limits of the distribution of the species and report its presence in Argentina.

Plocopsylla (P.) inti is cited for the first time in Argentina, extending its distribution ∼ 970 km further south than previously documented. New locality data and flea-host associations are recorded. The contributions of this study are relevant because they increase knowledge of the diversity of flea fauna in northwestern Argentina bordering a plague endemic area and will be useful in the implementation of plague control management plans in the future.

It is a member of the lineage consisting in Octodontomys as a sister clade containing Octodon and of a clade represented by Spalacopus and Aconaemys . Although the external and cranio-dental morphology have been well studied, little is known of the postcranial morphology of S . cyanus . Because of the peculiarities of its lifestyle and locomotion among the members of the family, it is interesting to characterize details of the morphology of the postcranial skeleton of this species and to infer their functional aspects of the morphology. Twenty-nine specimens with postcranial material stored in two collections were studied: Museo de La Plata (MLP), La Plata, Buenos Aires, Argentina and Coleccion de Mamiferos del Instituto de Ciencias Ambientales y Evolutivas (UACH), Universidad Austral de Chile, Valdivia,...

A pesar de que los registros geográficos de las especies están bien documentados, sus patrones distribucionales a escala nacional no han sido estudiados hasta el momento. En este trabajo analizamos la totalidad de los registros validados, con el fin de identificar patrones de riqueza de especies y congruencia distribucional. La mayor riqueza específica se concentra en la Selva Paranaense y en las Yungas y se observa una marcada caída de riqueza en el gradiente latitudinal. La coincidencia de los rangos geográficos de las especies define un total de 47 áreas de congruencia distribucional consenso, y cada una fue asignada a uno de los ocho patrones identificados: las Yungas, el sector norte de las Yungas (anidado con el anterior), el noreste, un patrón disyunto que incluye el noroeste y el noreste del país, la región chaqueña unida a otras regiones circundantes y la región patagónica. Cincuenta y un especies (76% del total) resultaron caracterizadoras. Varios de los patrones encontrados son coincidentes con áreas recuperadas para otros organismos (vegetales y animales), aspecto que podría sugerir la existencia de áreas con historias comunes para gran parte de la biota de la región. ABSTRACT. Biogeographic patterns of the bats of Argentina: species richness and distributionalcongruence. Currently 67 species of bats are recognized for the fauna of Argentina. Notwithstanding the geographical records of the species are well documented, their distributional patterns on a national scale have not been studied so far. In this study, we analyze all the validated records, in order to identify patterns of species richness and distributional congruence. The highest species richness was located in the Paraná forest (northeast) and the Yungas forest (northwest), with a marked drop in richness in the latitudinal gradient. The coincidence of the geographical ranges of the species defined a total of 47 consensus areas of distributional congruence, and each one was assigned to one of eight identified patterns: the Yungas, the northern sector of the Yungas (nested with the previous one), the northeast, a disjunct pattern that includes the northwest and northeast of the country, the Chaco region along with other surrounding regions, and the Patagonian region.

A modo de comparación se ha analizado también las especies que habitan las Yungas de Bolivia. Desde mediados de los años '70 se han desarrollado estudios intensivos de campo a numerosas localidades de las Yungas en Argentina. A esta información se ha agregado la obtenida en colecciones científicas, con un total de 1682 ejemplares examinados, así como los registros de la literatura. Como resultado, se ha definido que las Yungas de Argentina contienen actualmente una especie de noctiliónido, 12 phyllostómidos, 13 vespertiliónidos y 13 molóssidos. Para cada especie se detallan los ejemplares examinados, registros adicionales, comentarios sobre diferentes aspectos de su biología, distribución, reproducción, y otros ...

We review the taxonomy of the flea genus Agastopsylla including the re-description of two species and one subspecies, and designate neotype and neallotype for Agastopsylla hirsutior, neotype for Agastopsylla nylota nylota from the "Colección Mamíferos Lillo Anexos" (CMLA), Universidad Nacional de Tucumán, Argentina, and neotype and neallotype for Agastopsylla pearsoni from the Natural History Museum (London, U.K.). Additionally, a key to identification of the species of Agastopsylla and a distribution map of the species of the genus are included.

We quantified the prevalence of leptospiral colonization in bats in the Peruvian Amazon in the vicinity of Iquitos, an area of high biologic diversity. Of 589 analyzed bats, culture (3 of 589) and molecular evidence (20 of 589) of leptospiral colonization was found in the kidneys, yielding an overall colonization rate of 3.4%. Infection rates differed with habitat and location, and among different bat species. Bayesian analysis was used to infer phylogenic relationships of leptospiral 16S ribosomal DNA sequences. Tree topologies were consistent with groupings based on DNA-DNA hybridization studies. A diverse group of leptospires was found in peri-Iquitos bat populations including Leptospira interrogans (5 clones), L. kirschneri (1), L. borgpetersenii (4), L. fainei (1), and two previously undescribed leptospiral species (8). Although L. kirschenri and L. interrogans have been previously isolated from bats, this report is the first to describe L. borgpetersenii and L. fainei infection of bats. A wild animal reservoir of L. fainei has not been previously described. The detection in bats of the L. interrogans serovar Icterohemorrhagiae, a leptospire typically maintained by peridomestic rats, suggests a rodent-bat infection cycle. Bats in Iquitos maintain a genetically diverse group of leptospires. These results provide a solid basis for pursuing molecular epidemiologic studies of bat-associated Leptospira, a potentially new epidemiologic reservoir of transmission of leptospirosis to humans.

The new record of this species increases its geographical distribution, previously known from Catamarca, Entre Ríos, and Buenos Aires Provinces. The examined materials correspond to a fragmentary hemimandible with m2-m3 and an isolated lower molar, which provide information on the occlusal morphology of Paramyocastor diligens in early ontogenetic stages.

In this work, I present information related to the diversity of bat species in the Amazonian region of Iquitos, Peru, where nearly 60% of the 152 bat species known to Peru recorded. Unlike in previous investigations in this area, bat surveys were designed to detect species living in urban and rural areas. The results have added a new bat species (Eumops delticus) to the Peruvian fauna, eight new species for the region around Iquitos (Peropteryx macrotis, Peropteryx pallidoptera, Anoura caudifer, Lionycteris spurrelli, Vampyrum spectrum, Thyroptera lavali, Cynomops planirostris, and Molossus coibensis), and a new species for Northeast Peru (Eumops maurus).

The fauna includes 9 orders, 29 families, 96 genera, and 141 species. A checklist of the extant species and species of probable occurrence is included, as is a gazetteer of localities. We review the literature published since the publication of Mares et al. (1981a) and Ojeda and Mares (1989), and include new collecting localities.

Myotis izecksohni and Myotis lavali were recently described from the States of Río de Janeiro, Paraná and Pernambuco, Brazil. These are clearly different from all other known species of the genus in their external and cranial characters, which are exactly comparable with our specimens collected in Argentina. This allows to greatly expand the known geographic distributions for these two species. The addition to Argentina of Myotis lavali with specimens collected in the Yungas ecoregion of Salta Province, and Myotis izecksohni with specimens collected in the Fields and Weedlands ecoregion of Misiones Province, increases the known ecoregions to date for the distribution of the two species.

Here we report the first record of H. magellanicus in the Maulino Temperate Forest of central Chile, a Mediterranean-climate ecosystem, suggesting that the species might not be exclusive to subantarctic forests, as previously thought. This constitutes the northernmost continental record for the species, extending its range ca. 400 km the previous known northern locality.

Jujuy Province supports 143 species of mammals, represented by 9 didelphimorphs, 10 edentates, 36 bats, 2 primates, 20 carnivores, 1 perissodactyl, 8 artiodactyls, 56 rodents, and 1 lagomorph. One of the species is new to science, 4 are new for argentina, 2 are new for NW argentina, and 14 are new for the province. Other species of mammals are here considered as probable for the province based on recent references or records we have yet to confirm; these include 1 xenarthran, 1 bat, 2 artiodactyls, and 3 rodents. additionally, 2 artiodactyls are probable according to historical records. Four introduced species (3 Muridae and 1 Leporidae) are not included in the checklist of species, and 5 species are excluded from Jujuy Province. Using these data we conducted a biogeographic analysis to determine the degree of similarity among the phytogeographic regions of Jujuy.

These rodents, highly adapted to desert environments, are semi-fossorial with capacity to move on the surface as well as to build burrows. The shape, structure, and size of the limbs are described. Contrary to what was expected for scratch digging semi-fossorial species, Tympanoctomys have slender humerus, radius and ulna; with narrow epicondyles of the humerus and short olecranon of the ulna with poorly developed processes. Following our descriptions, no intrageneric morphological variation regarding to the configuration of the limbs was detected, probably due to phylogenetic proximity, and not related to specific variations in response to different use of substrates or habits. The obtained results constitute a source of previously unpublished information as well as an important base for future analysis in different studies, such as morphometric, morpho-functi...

These rodents, highly adapted to desert environments, are semi-fossorial with capacity to move on the surface as well as to build burrows. The shape, structure, and size of the limbs are described. Contrary to what was expected for scratch digging semi-fossorial species, Tympanoctomys have slender humerus, radius and ulna; with narrow epicondyles of the humerus and short olecranon of the ulna with poorly developed processes. Following our descriptions, no intrageneric morphological variation regarding to the configuration of the limbs was detected, probably due to phylogenetic proximity, and not related to specific variations in response to different use of substrates or habits. The obtained results constitute a source of previously unpublished information as well as an important base for future analysis in different studies, such as morphometric, morpho-functi...

The specimen corresponds to a complete head, with skull included, preserved in alcohol, collected by Dr.
Clave de Identificación de los Murciélagos Neotropicales - Chave de Identificação dos Morcegos Neotropicais, 2021
Para facilitar esfuerzos de identificación de murciélagos en la región, ponemos a disposición la ... more Para facilitar esfuerzos de identificación de murciélagos en la región, ponemos a disposición la presente clave de identificación, estructurada a nivel de familias, subfamilias, géneros y especies, incluyendo a todas aquellas citadas hasta ahora para la región neotropical. Se incluyen mapas de la región Neotropical para indicar los países y territorios que la integran, y tablas por regiones y familias en las que se indican los países donde encuentran las especies. El objetivo principal de esta clave es que sea de utilidad para la identificación de especies, no sólo por investigadores en el área específica, sino también por estudiantes, guardaparques y público en general y que, al mismo tiempo, ayude a incentivar estudios sobre este grupo de mamíferos en la región. Los caracteres utilizados en la clave han sido seleccionados para ayudar, principalmente, en la identificación de especies en el campo pero, debido a que para muchas de las especies nuevas nombradas en los últimos tiempos no se ofrecen caracteres muy evidentes de su morfología externa, hemos tenido que agregar caracteres craneales y de la dentición, algunos de los cuales no son fáciles de observar en el campo ni sencillos de interpretar por observadores no especializados en el estudio de los murciélagos. A pesar de esto la clave permitirá, en el campo, una aproximación muy cercana hasta el nivel de especie en casi todos los casos. Al final se agrega una versión de la clave traducida al portugués. En la actualidad reconocemos para el Neotrópico nueve familias, 106 géneros y aproximadamente 450 especies de murciélagos: 22 Emballonuridae, 226 Phyllostomidae, 18 Mormoopidae, 2 Noctilionidae, 2 Furipteridae, 5 Thyropteridae, 11 Natalidae, 56 Molossidae y 108 Vespertilionidae. Respecto las especies por país, aunque existe la misma cautela respecto a diferencias en la taxonomía en uso por cada autor, los datos son los siguientes, indicando los confirmados (y los probables entre paréntesis): SUDAMÉRICA: Argentina 67, Bolivia 146 (1), Brasil 181 (4), Colombia 217 (4), Chile 14, Ecuador 183 (3), Guyana 125 (6), Guayana Francesa 101 (2), Paraguay 57 (2), Perú 188 (2), Surinam 99 (8), Uruguay 22 (3) y Venezuela 172 (2); NORTEAMÉRICA: México 141 (2); CENTROAMÉRICA: Belice 71 (11), Costa Rica 117, El Salvador 68 (3), Guatemala 104, Honduras 113 (2), Nicaragua 111, Panamá 112; CARIBE: Antillas Mayores: Cuba 26, Haití 17, Jamaica 22, Puerto Rico 13, República Dominicana 18; Antillas Menores: Antigua y Barbuda 7 (1), Barbados 10, Dominica 12 (1), Granada 15, San Cristóbal y Nieves 10, San Vicente y Las Granadinas 11, Santa Lucía 9, Trinidad y Tobago 67 (1).

Especies afines: por el gran tamaño corporal, orejas y la forma de la hoja nasal no puede confundirse con otras especies. Tonatia bidens tiene un aspecto similar, pero es de menor tamaño. Alimentación: carnívora; incluye pequeños vertebrados como aves, reptiles, murciélagos y roedores; algunos autores han reportado la ingesta de insectos y de frutos. Refugios: cuevas y túneles, en lo más denso de los bosques.
