A new species of Anomaloglossus (Anura: Aromobatidae) from the Pakaraima Mountains of Guyana Vrije Universiteit Brussel
We describe a new species of Anomaloglossus from the Pakaraima Mountains of Guyana. Anomaloglossus megacephalus sp. nov. is currently known from Maringma Tepui at 1060 m elevation and from Mt. Ayanganna at 1490 m elevation. The new species can be distinguished from all known congeners by the following combination of characters: relatively large size (females up to 28.3 mm), head large, Finger I subequal or shorter than II, the tip of Finger IV ...
Two new endangered species of Anomaloglossus (Anura: Aromobatidae) from Roraima State, northern Brazil Vrije Universiteit Brussel
We describe two new species of Anomaloglossus from Roraima State, Brazil, that are likely endemic to single mountains currently isolated among lowland forest and savanna ecosystems. The first species, Anomaloglossus tepequem sp. nov. was collected in 1986 and 1992 along a single stream at >500 m elevation on a tepui-like mountain named Tepequém, but was not detected during recent investigations. It is mainly diagnosed from other ...
Cryptic diversity in Amazonian frogs: Integrative taxonomy of the genus Anomaloglossus (Amphibia: Anura: Aromobatidae) reveals a unique case of diversification within the Guiana Shield Vrije Universiteit Brussel Universiteit Antwerpen
Lack of resolution on species boundaries and distribution can hamper inferences in many fields of biology, notably biogeography and conservation biology. This is particularly true in megadiverse and undersurveyed regions such as Amazonia, where species richness remains vastly underestimated. Integrative approaches using a combination of phenotypic and molecular evidence have proved extremely successful in reducing knowledge gaps in species ...
A new species of Anomaloglossus (Anura: Aromobatidae) of the stepheni group with the redescription of A. baeobatrachus (Boistel and de Massary, 1999), and an amended definition of A. leopardus Ouboter and Jairam, 2012 Universiteit Antwerpen Vrije Universiteit Brussel
Anomaloglossus is a species-rich genus of frogs endemic to the Guiana Shield that still harbors several unnamed species. Within the A. stepheni species group (which includes four valid nominal species), A. baeobatrachus has an uncertain taxonomic status, notably because the holotype was an unvouchered specimen depicted in a popular journal. Another member of this group, A. leopardus, was only superficially described, lacking information on the ...
A New Diagnosis and Description of Anomaloglossus roraima (La Marca, 1998) (Anura: Aromobatidae: Anomaloglossinae), with Description of Its Tadpole and Call Vrije Universiteit Brussel
La rana Anomaloglossus roraima fue originalmente descrito como Colostethus roraima por E. La Marca en 1998 con base a un único e inmaduro ejemplar hembra, recolectado a 2700 m de elevación sobre la parte alta del monte Roraima, un tepui (macizo montañoso) locali- zado en el sureste de Venezuela. Se ofrece una redescripción de la especie con base a nuevos ejemplares del Wei-Assipu-tepui y Maringma-te- pui en Guyana. La redescripción incluye su ...
A redescription of Anomaloglossus praderioi (La Marca, 1998) (Anura: Aromobatidae: Anomaloglossinae), with description of its tadpole and call Vrije Universiteit Brussel
Anomaloglossus praderioi was originally described as Colostethus praderioi by E. La Marca in 1998 on the basis of two male specimens. The present paper provides a redescription of the species on the basis of new material from Maringma Tepui in Guyana and an additional specimen from Sierra de Lema in Venezuela. The redescription includes descriptions of the tadpole and vocalisation. Anomaloglossus praderioi is a medium-sized species mainly ...
On the brink of extinction Vrije Universiteit Brussel Universiteit Antwerpen
A large portion of the amphibian species occurring in Amazonia remains undescribed. A recent study on species delineation in Anomaloglossus, a genus endemic to the Guiana Shield, demonstrated the existence of two undescribed species previously identified as A. degranvillei, which we describe herein. In addition to divergence at the molecular level, these two new taxa are also distinguished by subtle morphological characters and substantial ...
