Full-text available
Integrative taxonomy (IT) is becoming a preferred approach to delimiting species boundaries by including different empirical criteria. IT methods can be divided into two types of procedures both of which use multiple kinds of evidence: step-by-step approaches test hypotheses by sequential evaluation in a hypothetic-deductive framework, while model-...

Bothrops pictus is a medically important pit viper endemic to Peru, usually found on the western slopes of the Andes, coastal foothills and river valleys along the central Pacific coast. Little is known about this species despite the fact it was described 177 years ago. In particular, the lack of DNA data has limited our knowledge of its phylogenet...

Telmatobius is the most diverse group of anurans in the Andean Altiplano (highlands) Morphologically, these amphibians have a generally conserved morphology but in turn present large intraspecific variation, which has led to a complex taxonomy and systematics. T. marmoratus has the widest distribution of the genus and forms a complex composed of at...

The taxonomic status of the strabomantid frog species Pristimantis nebulosus (Henle, 1992), originating from the southern Cordillera Azul in central Peru, is investigated based on examination of the holotype and its comparison with freshly collected topotypic material. Following current standards, we provide a redescription of the holotype. It is i...

We studied the status of toads of the genus Rhinella collected in the southern Cordillera Azul, central Peru. Molecular analysis of the mitochondrial 16S rRNA gene revealed them to be members of the recently proposed Rhinella festae species group, and sister to R. lilyrodriguezae, a species known from northern areas of the Cordillera Azul. The new...

A new species of the genus Stenocercus is described from the Peruvian coastal desert in the Ica region. The new species is similar in ecology and morphology to Stenocercus modestus, but differs from it in lacking an oblique neck fold, a distinct patch of small scales posterior to the lateral region of the neck, and bright yellow lateral dots on the...

This study assessed the diet of the Neotropical lizard Liolaemus polystictus from Huancavelica region in the Peruvian central Andes. The diet composition was identified from 54 sample stomach contents. Percentage of vegetable content was higher than the animal one (V% animal content= 22.97 and V% vegetable content= 77.03), and arthropods were the h...
Article
The Rhinella spinulosa group is a clade of toads that inhabit the Andes mountains from northern Ecuador to Patagonia. Its taxonomy was recently revised, and in its new arrangement comprises nine species, including Rhinella gallardoi, traditionally placed in a different intrageneric group. In this work we studied the larval external and internal mor...
Article
We describe a new species of Adenomera from southwestern Amazonia. The new species corresponds to one of the acoustic patterns and morphotypes from Tambopata National Reserve (Adenomera ‘‘Forest Call II’’), which was associated with the candidate species identified via molecular data as Adenomera sp. C in the phylogeny of the genus. The new species...

Se revisa el estado taxonómico de Gastrotheca peruana usando métodos loge- né cos en base a secuencias de 16S rRNA. Los árboles de máxima verosimilitud y Bayesiano mostraron que las variantes génicas de G. peruana forman dos clados que no son hermanos. Uno de estos clados se distribuye en el norte de Perú, incluyendo un individuo procedente de la l...

Se describe el renacuajo de Telmatobius brachydactylus desde el estadio 30 al 41 de Gosner. El renacuajo de T. brachydactylus es similar a las otras larvas de Telmatobius con morfología de tipo poza, pero se diferencia de la especie simpátrica, Telmatobius macrostomus, por tener la cola más larga en relación al cuerpo y una longitud total significa...
Article
Adenomera andreae and A. hylaedactyla are two widespread Amazonian frogs that have been traditionally distinguished from each other by the use of different habitats, toe tip development, and more recently through advertisement calls. Yet, taxonomic identification of these species has always been challenging. Herein we undertake a review of type spe...

Three new species of Liolaemus belonging to the L. montanus group are described from Perú. Two new species are restricted to the Ica and Moquegua departments on the Pacific coast, and one new species is only known from an isolated highland in Ayacucho department. These three new species differ from closely related species in their coloration patter...

Convergence is a pervasive phenomenon in the Tree of Life, and evolution of similar phenotypes sharing the same environmental conditions is expected in phylogeneti-cally closely related species. In contrast, contingent factors are probably more influential in shaping phenotypic diversity for distantly related taxa. Here, we test putative convergent...
Article
Species delimitation in Phymaturus has been a difficult task due to the highly conserved morphological and ecological features present in this genus. Almost all species of Phymaturus have been described without DNA data or lacking statistical analyses which makes even more difficult to compare species. Although two molecular phylogenetic studies ha...

Subsequent to the Miocene (approximately 35 Mya), Borneo has served as an insular refuge and a source of colonization for a broad range of species emigrating to others parts of Sundaland. A phylogeny-based historical biogeographical hypothesis for the Stream Toad genus Ansonia supports multiple instances of an out-of-Borneo scenario. An ancestral r...

A new species of limestone cave-adapted gecko of the Cyrtodactylus pulchellus complex, C. hidupselamanya sp. nov., is described from an isolated karst formation at Felda Chiku 7, Kelantan, Peninsular Malaysia. This formation is scheduled to be completely quarried for its mineral content. From what we know about the life history of C. hidupselamanya...

An integrative taxonomic analysis used to identify a new population of Bronchocela from Phuket Island, Thailand indicates it is conspecific with B. rayaensis from the Langkawi Archipelago of northwestern Peninsular Malaysia. An additional specimen photographed from Khura Buri District, Phang-nga Province is also considered to be B. rayaensis and re...
Article
Viviparity is a remarkable feature in squamate sauropsids and it has evolved multiple times in parallel with the formation of a placenta. One example of this repeated evolution of viviparity and placentation occurs in the species-rich South American genus Liolaemus with at least six independent origins of viviparity. However, evolutionary studies o...

The Liolaemus alticolor-bibronii group (subgenus Lioalemus) is distributed over a wide altitudinal and latitudinal geographic range, from central Perú to southern Argentina (Fig. 1A) and currently includes 30 known species. Current hypotheses of phylogenetic relationships are mostly based on morphological evidence (Quinteros 2013), but lack of reso...

Species delimitation studies based on integrative taxonomic approaches have received considerable attention in the last few years, and have provided the strongest hypotheses of species boundaries. We used three lines of evidence (molecular, morphological, and niche envelopes) to test for species boundaries in Peruvian populations of the Liolaemus w...

It is predicted that climate change will cause species extinctions and distributional shifts in coming decades, but data to validate these predictions are relatively scarce. Here, we compare recent and historical surveys for 48 Mexican lizard species at 200 sites. Since 1975, 12% of local populations have gone extinct. We verified physiological mod...

Batrachophrynus and Telmatobius are the two genus of Telmatobiinae from the central Andes. Both genera have species with adaptations for life at high altitude in the Andes, with aquatic or semi-aquatic habits in creeks, lagoons and lakes. The objective of this study is to evaluate the phylogenetic relationships between Batra- chophrynus and 13 spec...
