The European hare was introduced into Argentina and Chile between the late 19th and early 20th centuries, and since then has progressed throughout South America. In 1983 the hare reached southern Brazil, the Tarija department in southern Bolivia, and the Copiapo River area in Chile. In 2002 and 2004 we see some wild hares in the departments of Tacna and Arequipa, up to an altitude of 4300 m. According to interviews with inhabitants of these areas, the hare reached Peru between 1995 and 1998, which would represent an minimal dispersal speed of 44,34 km per year from Tarija. The interviewed subjects explained that the hare served no use but created problems by consuming vegetation. The present notice is a warning against the arrival of the European hare in Peru and the possible consequences of its presence.

A new species of Mummuciidae, Mummucina huaripampae sp. nov., from Huaripampa, between 3352 and 3568 m a.s.l. in the department of Junín, central Peru, is described and illustrated. This is the first Mummucina species registered for Junín, and the fourth for Peru. With this description, the number of known Mummucina species rises to seven.

This study describes and illustrates a new species of arachnid, the pseudoscorpion Stenolpium sayrii sp. nov., collected at Pucllana, an archaeological site in the city of Lima, Peru. With this description, the total number of known Stenolpium species worldwide reaches eight, and in Peru specifically, it increases to seven. The discovery of this new species in Peru's most populous city serves as an exemplar highlighting the extensive scope for further research on Peruvian fauna in general, particularly on its arachnids.

This study characterized the diet of Leopardus colocolo from the surroundings of Junín lake, in the center of Peru, from prey remnants found within 43 scats. Origin of predator scats was determined from mitochondrial DNA from intestinal epithelial cells existing on the surface of the scats, using as a marker the control region. The prey remnants were identified using specialized literature and comparison with a voucher collection, identifying a total of 14 food items belong to mammals of Cricetidae (6), Chinchillidae (1) and Caviidae (1) families, birds of Anatidae (3) and Rallidae (2) families and one group of unidentified birds. The rodents were the main component of the diet of L. colocolo, in frequency and biomass, followed by birds. Among the food items consumed, the small cricetine rodent Calomys sp. was the most frequent; however, the greatest relative biomass contribution was pr...

Este estudio caracteriza la dieta de Leopardus colocolo en los alrededores del lago Junín, en el centro del Perú, a partir de los restos de las presas presentes en 43 heces. El origen de las heces del predador se determinó a partir del ADN mitocondrial de las células epiteliales intestinales adheridas a la superficie de las heces, utilizando como marcador la región de control. Los restos de las presas fueron identificados utilizando literatura especializada y la comparación con especímenes de colección, identificando un total of 14 ítems alimenticios pertenecientes a mamíferos de las familias Cricetidae (6), Chinchillidae (1) y Caviidae (1) y aves de las familias Anatidae (3) y Rallidae (2), y un grupo de aves no identificadas (1). Los roedores fueron el principal componente de la dieta de L. colocolo, en frecuencia y biomasa, seguido por las aves. Entre los ítems alimenticios...

New evidence on the presence of the Machupicchu Arboreal Chinchilla Rat (Cuscomys oblativus: Abrocomidae) from Machupicchu Historic Sanctuary are reported, using camera tramps during april 2018 to april 2019. 67 photographic records were obtained in five mountain forest localities between 2842 and 3413 meters of altitude. All the records correspond to adult specimens and present nocturnal habits with more activity from 10 pm to 04 am. At the moment, no records are known of C. oblativus outside the Machupicchu, being one of the three endemic mammal species of the protected natural area.

Se reporta por primera vez la presencia del tigrillo u ocelote (Leopardus pardalis), en el Santuario Histórico de Machupicchu, mediante el uso de cámaras trampa. Se obtuvieron 21 registros fotográficos independientes en cuatro sectores de bosque montano entre junio de 2018 y marzo del 2020. El rango altitudinal registrado para esta especie dentro del Santuario comprende desde 2193 hasta 3414 m de altitud, lo que incluye el segundo registro a mayor elevación en el Perú. Los registros indican un patrón de actividad catemeral, es decir sin ninguna preferencia de actividad horaria entre el día y la noche, y sugieren que la presencia de tigrillo en algunas áreas a más de 3000 m puede ser más común de lo que se pensaba, con ejemplares presentes todo el año.
