It is distributed from approximately 27°18’S – 70°25’W in the north (Atacama) to 36°00’S – 73°7’W in the south (BíoBío). We report the finding of a cranium in excellent conditions, which is the first record of this species in the coastal shrubby Mediterranean desert of the Antofagasta Region.

  • New Record of Abrocoma Bennetti Murrayi (Rodentia, Abrocomidae) from the Atacama Region
    Volumen 30, Nº 2. Páginas 115-118 IDESIA (Chile) Mayo-Agosto, 2012 New record of Abrocoma bennetti murrayi (Rodentia, Abrocomidae) from the Atacama Region. Extension of distribution range in Chile Nuevo hallazgo de Abrocoma bennetti murrayi (Rodentia, Abrocomidae) en la Región de Atacama. Extensión de su rango de distribución en Chile Pablo Valladares1, Claudio Campos2 ABSTRACT The present note reports the first record of the rodent Abrocoma bennetti (Waterhouse 1837) for the Copiapó Valley, located between the cities of Copiapó and Caldera, Chile. Specimens were captured and then released to their natural environment. This record extends the northern and northwestern distribution limits of this rodent from Vallenar to Copiapó (ca. 145 km) and from Ramadilla to Copiapó (ca. 120 km), respectively. Other species collected were Oligoryzomys longicaudatus and Abrothrix olivaceus. We present a map of the new distribution range for this species based on taxonomic collections and previously published papers. Key words: chinchilla rat, Abrocoma, Copiapó, distribution. RESUMEN En la presente nota reportamos el primer registro de Abrocoma bennetti para el valle de Copiapó. Los especímenes fueron capturados y luego liberados a su ambiente natural en la localidad de Piedra Colgada. Este nuevo registro extiende su rango de distribución desde el valle de Vallenar a Copiapó en 145 kilómetros, y desde Ramadilla a Copiapó en 120 kilómetros, respectivamente. Otras especies colectadas en la zona fueron Oligoryzomys longicaudatus y Abrothrix olivaceus. Presentamos un mapa con el nuevo rango de distribución para la especie basada en la revisión de colecciones taxonómicas y artículos previamente publicados. Palabras claves: ratón chinchilla, Abrocoma, Copiapó, distribución.

  • Distribution of Two Andean Small Cats (Leopardus Jacobita and Leopardus Colocolo) in Bolivia and the Potential Impacts of Traditional Beliefs on Their Conservation

Field interviews were con- ducted with local villagers, in parallel with an intensive search for direct and/or indirect signs of the 2 species. Confirmed records for the Andean cat suggest that the species is mainly restricted to the high Andean region of Bolivia (elevations above 4100 m), whereas the pampas cat can be found both in this region and at lower elevations. Most of the confirmed records were for the pam- pas cat, suggesting that it is more abundant than the Andean cat. Both species are generally referred to by local people as ‘titi’ and are culturally associated with Earth’s abundance and fertil- ity.
