Integrative taxonomy and preliminary assessment of species limits in the Liolaemus walkeri complex (Squamata, Liolaemidae) with descriptions of three new species from Peru
The phylogenetic analysis shows that L. walkeri, L. tacnae and the three new species are strongly separated from other species assigned to the alticolor-bibronii group, and this highlights the need to integrate other sources of data to erect strong hypothesis of species limits.

A large proportion of hidden diversity is document within a set of populations that were previously treated as a single, widely distributed species, Osteocephalus buckleyi, and three new species are described.
Phylogeny and biogeography of the most diverse clade of South American gymnophthalmid lizards (Squamata, Gymnophthalmidae, Cercosaurinae).
Systematics of the Dendropsophus leucophyllatus species complex (Anura: Hylidae): Cryptic diversity and the description of two new species
Assessment of phylogenetic relationships and species boundaries of two Amazonian species of the Dendropsophus leucophyllatus species group reveals the existence of five confirmed and four unconfirmed species, including the most widely distributed species, D. triangulum sensu lato.
Two new species of Andean gymnophthalmid lizards of the genus Euspondylus (Reptilia, Squamata) from central and southern Peru
Two new species of lizards assigned to the genus Euspondylus from the montane forests of the Peruvian Andes in the Pasco Department and Ayacucho Department both at elevations of 2550 and 3450 m, respectively, are described.
Taxonomic revision and phylogenetic position of Osteocephalus festae (Anura, Hylidae) with description of its larva
A phylogeny based on mitochondrial DNA sequences, genes 12S and ND1, shows that Osteocephalus festae is closely related to OsteOcephalus buckleyi, Osteecephalus mutabor and Osteacephalus verruciger, which is characterized by stream dwelling tadpoles.
Morphological Variation of Atractus carrioni (Serpentes: Dipsadidae)
New localities and data on meristic, morphometric, color pattern, and hemipenis variation for Atractus carrioni are reported, which associate the variation displayed by these character systems with sexual, geographic, and ontogenetic phenomena.
A new bush anole (Iguanidae, Polychrotinae, Polychrus) from the upper Marañon basin, Peru, with a redescription of Polychrus peruvianus (Noble, 1924) and additional information on Polychrus…
A new colorful species of Polychrus with a conspicuous sexual dimorphism from the dry forest of the northern portion of Región de La Libertad, Peru, which has very small dorsal scales and thus a higher number of scales around midbody and in the middorsal line.
A new species of arboreal microteiid lizard of the genus Euspondylus (Gymnophtalmidae: Cercosaurinae) from the Andean slopes of central Peru with comments on Peruvian Euspondylus.
A new species of arboreal gymnophtalmid lizard from the eastern Andean slopes in central Peru is described and a revision of the type material of E. maculatus is included to clarify morphological differences with the new species.
Two New Sympatric Species of Leaf-Toed Geckos (Gekkonidae: Phyllodactylus) from the Balsas Region of the Upper Marañon Valley, Peru
Two new species of the genus Phyllodactylus are described based on material collected in the southern portion of Departamento de Amazonas, Peru, and exhibit some similarities to other assemblages of sympatrics in South America.
