Euparkerella
Euparkerella is a genus of craugastorid frogs. The common name coined for them is Guanabara frogs. They are endemic to Atlantic coastal forests in the southeastern Brazilian states Espírito Santo and Rio de Janeiro. 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. Taxonomy. The phylogenetic position of "Euparkerella" is uncertain as they have not been included in any molecular phylogeny. On the basis of their morphological similarity to "Holoaden", they are provisionally placed in subfamily Holoadeninae. The AmphibiaWeb keeps Holoadeninae , and consequently "Euparkerella", in Strabomantidae, a family no longer recognized by the Amphibian Species of the World. "Euparkerella" species 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. Description. "Euparkerella" are small frogs, growing to snout–vent length at most. The digits are extremely reduced, compared to those of their larger relatives. Head is narrower than the body. Differentiated tympanic membrane and tympanic annulus  are absent. Dorsum is finely granular. Venter is areolate. Species. The following species are recognized in the genus "Euparkerella":
