—A new species of Eleutherodactylus is described from the Serranı́a de Pirre, Darién Province, Panama. This species is similar to Eleutherodactylus altae and Eleutherodactylus pardalis, but can be differentiated by the lack of red or white spots on groin and limbs. RESUMEN.—Se describe una especie nueva de Eleutherodactylus de la Serranı́a de Pirre, Provincia de Darién, Panamá. Esta especie se as...

Amphibian taxonomy is currently experiencing rapid changes, particularly within eleutherodactyline frogs, as a result of DNA Abstract A new species of the Eleutherodactylus lacrimosus assemblage (Anura, Brachycephalidae) from the lowland rainforest canopy of Yasuni National Park, Amazonian Ecuador. A new species of Eleutherodactylus from the lowland rainforest canopy in northeastern Amazonian E...

-Eleutherodactylus fraudator, new species, E. mercedesae, new species, and E. rhabdolaemus are reported from cloud forests in Departamento Cochabamba, Bolivia. Eleutherodactylus pharangobates Duellman is placed as a synonym oíE. rhabdolaemus Duellman. Although the genus Eleutherodactylus is extraordinarily speciose in many areas of northern South America and especially on the Andean slopes, it ...

Advertisement calls can be used to aid solving taxonomic problems and understanding the evolution of certain groups. In this study, the advertisement call of Eleutherodactylus bilineatus is described. It is composed by two different notes with a total duration of 0.529–4.241 seconds and dominant frequency of 1.72–3.45 kHz. Additionally, new data is provided on the geographical distribution of E...

We describe two new species of Eleutherodactylus, subgenus Syrrhophus, from two separate mountain ranges in western Mexico. Eleutherodactylus grunwaldi sp. nov. inhabits the Sierra de Manantlán in Colima and Jalisco from 1300 to 2200 m, whereas E. wixarika sp. nov. is known from a single locality in the Sierra Huichola of northern Jalisco at 2400 m, but is probably more widespread. Eleutherodac...

Direct development in amphibians is an evolutionarily derived life-history mode that involves the loss of the free-living, aquatic larval stage. We examined embryos of the direct-developing anuran Eleutherodactylus coqui (Leptodactylidae) to evaluate how the biphasic pattern of cranial ontogeny of metamorphosing species has been modified in the evolution of direct development in this lineage. W...

A N adult anuran can still walk or swim if the nerves supplying one or even two limbs are de-afferentated (Gray, 1950). However, in a developing amphibian, a limb at motile stages becomes paralysed when deprived of its sensory input. A sequence of degenerative changes then follow in the cord and in peripheral nerves. Tadpoles of Bufo marinus and late embryos of Eleutherodactylus martinicensis h...

In cases where uninvolved bystanders pay to punish defectors, this behavior has typically been interpreted in terms of group-level rather than individual-level benefits. Male cleaner fish, Labroides dimidiatus, punish their female partner if she cheats while inspecting model clients. Punishment promotes female cooperation and thereby yields direct foraging benefits to the male. Thus, third-part...

Four phylogenetically independent lineages of frogs are currently known to sequester lipid-soluble skin alkaloids for which a dietary source has been demonstrated. We report here a remarkable fifth such instance, in Eleutherodactylus iberia and Eleutherodactylus orientalis, two species of miniaturized frogs of the family Eleutherodactylidae from Cuba. Six pumiliotoxins and two indolizidines wer...
