Article
Full-text available
A new lizard of the genus Liolaemus is described from the Tacna region of southern of Peru. This species belongs to the L. montanus group and was initially thought to be L. poconchilensis and L. insolitus. However, a series of diagnostic characters differentiate it consistently from these two species and all other species of the genus. To determine...

The diversity of reptiles in the Andes of southwestern Peru is poorly documented. Despite the fact that studies on saurians have intensified in recent years, mainly in the genus Liolaemus, information gaps on the biodiversity of this area remain. Such is the case of the Reserva Paisajística Subcuenca del Cotahuasi (RPSCC), Department of Arequipa, w...

The southwestern Andes of Peru harbor a hidden taxonomic diversity of reptiles. We describe a new species of Liolaemus Wiegmann (Iguania: Liolaemidae) from xerophytic environments of the southwestern slopes of the Andes of Peru, 2,400-2,900 m asl. The new species, previously considered to be a population of L. insolitus Cei, exhibits unique diagnos...
Article
Full-text available
The Andes of southern Peru contain a biodiversity with high degree of endemism due to its peculiar geography and bioclimate. In this work a new endemic species of the genus Liolaemus is described which would be restricted to an altitude between 3870–4100 m s.n.m., in the Salado river basin of the district and province of Espinar, department of Cusc...
Article
Full-text available
The known diversity of the genus Liolaemus continues to increase, principally due to its great degree of endemism, the increasing number of researchers working on it, and advances in the taxonomic and phylogenetic knowledge of the genus. This diversity positions Liolaemus as the second most species-rich tetrapod genus. The present work adds to evid...
Article
Full-text available
The desert of southern Peru and northern Chile is an area with a high degree of endemism in squamate reptiles. In this work, an endemic new species is described in the genus Liolaemus with a restricted geographical distribution on the western slopes of the La Caldera batholith in the Department of Arequipa, southern Peru, that inhabits the Desert p...
Article
Full-text available
Integrative evidence of several external morphological characters and molecular phylogenetic analyses of mitochondrial DNA (12S, cyt-b) are used to place a new species of Andean lizard of the genus Liolaemus (Iguania: Liolaemidae) in the Liolaemus montanus group and as sister group of the clade formed by L. signifer. The new species is characterize...
Article
The South American lizard genus Liolaemus comprises > 260 species, of which > 60 are recognized as members of the Liolaemus montanus group, distributed throughout the Andes in central Peru, Bolivia, Chile and central Argentina. Despite its great morphological diversity and complex taxonomic history, a robust phylogenetic estimate is still lacking f...
Article
We present data showing that the number of salamander species in Amazonia is vastly underestimated. We used DNA sequences of up to five genes (3 mitochondrial and 2 nuclear) of 366 specimens, 189 corresponding to 89 non-Amazonian nominal species and 177 Amazonian specimens, including types or topotypes, of eight of the nine recognized species in th...
Article

The genus Liolaemus presents great diversity among the current tetrapods. It is the second genus with the highest number of valid species described of the Iguana infraorder. In this study, we described a new species of sand lizard from the coastal lomas of Quilca, La Chira and Ocoña that belongs to the subgenus Eulaemus and group of Liolaemus monta...

Full-text available
The Liolaemus montanus group is a diverse group of lizards that ranges from central Peru to southwestern Mendoza, Argentina, including much of the Plurinational State of Bolivia (“Bolivia”) and Chile. The species of this group mainly inhabit high elevation areas with cold temperatures. In the last years, several species of this group have been desc...

Major threats to the Andean bear (Tremarctos ornatus) include habitat fragmentation and anthropogenic-caused mortality related to hunting and human–bear conflicts (HBC). The Andean bear is listed as vulnerable (VU) globally (Vélez-Liendo and García-Rangel 2017), and also under Peruvian law, but conservation efforts are increasing. In Peru, these ef...

El conflicto humano-oso es un tema conocido, pero sobre ello existe escasa información y pocos estudios en nuestro país. Sin embargo, las nuevas políticas y herramientas de gestión de fauna silvestre están sentando las bases para los próximos trabajos relacionados con la conservación de esta especie. El presente documento tiene la finalidad de brin...

Description and phylogenetic relationships of a new species of Liolaemus (Iguania: Liolaemidae) and notes on the L. montanus group of Peru. A new lizard species of the Liolaemus montanus group endemic of the Andes western slope, Huaytará Province, Huancavelica, Peru is described. This new species of Liolaemus is of medium size (maximum SVL 70.1 mm)...

We describe and name a new species of poison-dart frog from the Amazonian slopes of the Andes in Manu Province, Madre de Dios Department, Peru; specifically within the Amarakaeri Communal Reserve and the buffer zone of Manu National Park. Ameerega shihuemoy sp. nov. is supported by a unique combination of characters: black dorsum with cream to ligh...

We name and describe a new species of Anura, Pristimantis iiap, from the lowlands of the Peruvian Amazon, and allocate it to the Pristimantis conspicillatus group (sensu Padial et al. 2014). The new species was collected along the Sepahua River, a small tributary of the Urubamba River (Departamento Ucayali, Peru) running west from the slopes of the...

We describe a new species of terrestrial frog of the genus Bryophryne (Anura: Craugastoridae) from the wet puna and elfin forests of the Amazonian versant of the Andes. The new species seems to be restricted to high altitude environments at elevations between 3506-3651 m in the area now protected by Megantoni National Sanctuary and Manu National Pa...

El fenómeno climático ENSO ocasiona cambios notables en la dinámica y estructura de los ecosistemas. Uno de estos cambios son las explosiones demográficas de algunas especies de roedores, conocidas como ratadas en el sur del Perú. En la última ratada de 1998 en Atiquipa, hemos registrado siete especies de roedores y un pequeño marsupial. Oryzomys...
