Euparkerella, sometimes known as Guanabara frogs, is a genus of frogs in the family Strabomantidae. [2] [3] They are endemic to the Atlantic coastal forests in the south-eastern Brazilian states of Espírito Santo and Rio de Janeiro. [2] [4] The name Euparkerella honours H. W. Parker, a herpetologist who named the type species, with the Greek prefix eu meaning true and suffix ella, a diminutive form. [5]

Taxonomy

Species of Euparkerella are traditionally distinguished using morphological traits. However, these species do not align well with genetically distinct units, with the latter suggesting higher diversity than the former, especially within Euparkerella brasiliensis and Euparkerella cochranae . It remains unresolved whether the genetically distinct units qualify as different species. [4]

Description

Species of Euparkerella are small frogs, growing to 22 millimetres (0.87 in) snout–vent length at most. The digits are extremely reduced, compared to those of their larger relatives. [4] Head is narrower than the body. Differentiated tympanic membrane and tympanic annulus are absent. Dorsum is finely granular. Venter is areolate. [5]

Species

The following species are recognized in the genus Euparkerella: [2] [3]

<i>Adelophryne</i> Genus of amphibians

Adelophryne is a genus of frogs in the family Eleutherodactylidae. They are native to northern South America east of the Andes, known roughly from the area corresponding to the Guiana Shield, as well as to the coastal area of Bahia, Brazil. Whether the genus is truly distinct from Phyzelaphryne remains uncertain. Common name shield frogs has been proposed for this genus, although the stem flea frog is used for some species.

<i>Barycholos</i> Genus of amphibians

Barycholos, common name Chimbo frogs, is a genus of small frogs in the family Strabomantidae found in south-eastern Brazil and tropical lowland Ecuador. The name Barycholos, from the Greek βαρύχολος ("savage"), is in honor of herpetologist Jay M. Savage.

Mount Duida frogs (Dischidodactylus), is a genus of craugastorid frogs endemic to the tepuis of southern Venezuela. The scientific name is derived from the Greek dischidos, meaning divided, and dactylos, meaning finger or toe, in reference to the divided ungual flap.

Ischnocnema is a genus of frogs from eastern Brazil and north-eastern Argentina. They comprise the former Eleutherodactylus from this region, but they are closer to Brachycephalus than the "true" Eleutherodactylus. Consequently, they are now placed in their own genus Ischnocnema in the family Brachycephalidae.
