ABSTRACT. We identified the species of bats and their roosts in the urban area of Lules, Tucuman. This is the first systematic study in Argentina in an urban area. Seven species were collected mainly housed in roofs, outstanding the collection of Eumops glaucinus, representing the second record of this species for the province.En Argentina, el conocimiento sobre los murciélagos urbanos y sus refugios es escaso (Romano et al. 1999;Vaccaro & Varela 2001;Varela et al. 2004), y no se han realizado estudios sistemáticos sobre el tema, siendo este tipo de estudios muy importantes ya que varios trabajos han demostrado que muchas especies que se registran en ciudades han representado novedades distribucionales y biogeográficas, y muchas veces han incrementado el número de especies conocidas para el área o región de registro (Barquez et al. 1999; Díaz 2011; Barquez et al., en prensa).Los objetivos del presente trabajo fueron identificar las especies que habitan el área urbana de Lules y su abundancia, determinar la presencia de refugios en las construcciones humanas y establecer las características de los mismos. Adicionalmente, se inspeccionaron áreas arboladas como jardines, plazas y parques. El estudio se realizó en la zona urbana de San Isidro de Lules (26°55'05.63''S, 65°20'52.71''O, 382 m snm), departamento Lules, provincia de Tucumán, ubicado a 22 km al SO de la capital de la provincia. Se colectaron murciélagos, entre enero de 2011 y enero de 2012, de ocho construcciones humanas, usando de una a cuatro redes de niebla de 6, 9 y 12 metros. En las áreas arboladas sólo se realizaron muestreos durante los meses más cálidos (primavera y verano). Se muestrearon un total de 6324 m × red (esfuerzo de captura) que corresponden a 367 horas en 95 noches. En cada uno de los refugios se registraron temperatura y humedad, tipo de construcción, altura máxima, tipo y número de refugios. Respecto a las variables ambientales, se registraron los datos de
Neotyphloceras crassispina hemisus Jordan is redescribed from male and female specimens collected at the type locality (Otro Cerro, Catamarca Province, Argentina) and nearby localities. New diagnostic morphological characters for both sexes are provided, which include the shape of the upper lobe of the fixed process of clasper, the crochet of the aedeagus and the shape and chaetotaxy of the distal arm of sternum IX for males, and the contour of the distal margin of sternum VII for females.
The mammalian and flea fauna of La Rioja Province is one of the least known from northwestern Argentina. In this study, the distribution and nomenclature of 13 species of fleas of bats and rodents from La Rioja Province are updated. Four species of fleas are recorded for the first time in La Rioja Province including a new record for northwestern Argentina, and two new flea-host associations. An identification key and distribution map are included for all known species of Siphonaptera of bats and rodents from La Rioja Province, Argentina.
We present the results obtained from 12 small-mammal surveys conducted between 1996 and 2013 in “Finca Las Capillas”, province of Jujuy, Argentina. This region has been formally recognized as an “Area of Importance for the Conservation of Bats” (AICOM) based on the diversity of species detected in our previous studies. This site in the Yungas forests of northwestern Argentina still maintains an excellent conservation status due to restrictions to human activities involving deforestation and limitations to cattle-raising imposed 50 years ago. A total of 39 species belonging to three orders, namely, Didelphimorphia, Chiroptera and Rodentia, were recorded. The species accumulation curve revealed that our records represent 83–95% of the community, and with high diversity indexes. Several of the genera and species that we recorded from our collection trips have been included in the fauna of Argentina. Our previous studies and the present findings provide new records for the province or significant extensions to previously known distributions of several taxa of small mammals. These results show that the site represents an icon for conservation in such a fragmented and exploited area as the Yungas in Argentina today.
A new species of flea (Siphonaptera: Rhopalopsyllidae) is described from sigmodontine rodents collected during a survey of small mammals in northwestern Argentina. The new species belongs to the subgenus
Tetrapsyllus
and can be distinguished from all species of the subgenus by characteristics of the modified abdominal segments and genitalia. A phylogenetic analysis of the genus
Tetrapsyllus
using morphological characters is presented and the analysis supports the erection of this new
Tetrapsyllus
species in the subgenus
Tetrapsyllus
. The unique occurrence of a sinus in the caudal margin of the sixth sternite of females that is present only in the subgenus
Tetrapsyllus
(also unique across the Order Siphonaptera) is provided with a discussion of how this adaptation is mirrored in the parallel development of a spur on the sclerotized inner tube of males. Additional host and locality data are recorded for
Tetrapsyllus
(
P
.)
bleptus
. A key to the genus
Tetrapsyllus
is provided. The increased diversity of flea fauna bordering a known plague endemic area in northwestern Argentina may prove useful in implementing sustainable control measures in the future.
