Species

Two species (see text)

Julianus is a genus of tree frogs in the family Hylidae. [1] Species of the genus are found in southeastern Brazil, Uruguay, and northeastern Argentina. [2] [3] This genus is considered poorly defined and is regarded by most to merely be a synonym of Scinax . [4]

This genus is named after Julián Faivovich, who has contributed a notable amount of knowledge to the study of South American tree frogs. [1] It was created because Scinax uruguayus differed from other Scinax in the larval oral disc morphology. [1] More specifically, the tadpole has two keratinized and pigmented plates on the lower jaw sheath, along with the posterior marginal papillae being larger than the papillae on the lateral margins. [5] The species Julianus pinimus was later added to this genus due to having similar features.

However, other papers claim that these frogs are not distinct enough to be grouped into an entirely different genus and should be readded to Scinax. This is because many of the characteristics used to define this genus are shared by other members of Scinax as well. [4] [6]

Species

There are two species in the genus Julianus. [1]

J. uruguayus is known from Treinta y Tres, Cerro Largo, and Tacuarembó in Uruguay, along with Santa Catarina, Brazil, and Corrientes, Argentina. [2] It may also occur in parts of Paraguay, but this is unconfirmed. J. pinimus is only known from a single locality in Minas Gerais, Brazil. [3]

Hylidae is a wide-ranging family of frogs commonly referred to as "tree frogs and their allies". However, the hylids include a diversity of frog species, many of which do not live in trees, but are terrestrial or semiaquatic.

<i>Scinax</i> Genus of amphibians

Scinax is a genus of frogs, commonly known as snouted treefrogs, in the family Hylidae. The genus is found from eastern and southern Mexico to Argentina and Uruguay, and in Trinidad and Tobago, and Saint Lucia. Member species are small to moderate-sized tree frogs, drably colored. Duellman and Wiens resurrected this genus in 1992. The name originates from the Greek word skinos, meaning quick or nimble.

<i>Sphaenorhynchus</i> Genus of amphibians

Sphaenorhynchus is a genus of frogs in the family Hylidae. They are also known as lime treefrogs or hatchet-faced treefrogs. They are found in the Amazon and Orinoco River basins of South America, the Guianas, Trinidad, and southern and eastern Brazil. The majority of the species are associated with the Atlantic Forest domain in Brazil.

<i>Pseudis</i> Genus of amphibians

Pseudis is a genus of South American frogs in the family Hylidae. They are often common and frequently heard, but easily overlooked because of their camouflage and lifestyle, living in lakes, ponds, marshes and similar waters with extensive aquatic vegetation, often sitting at the surface among plants or on floating plants, but rapidly diving if disturbed. Whereas the adults are medium-sized frogs, their tadpoles are large; in some species the world's longest.

<span class="mw-page-title-main">Spikethumb frog</span> Genus of amphibians

Spikethumb frogs are a genus (Plectrohyla) of frogs in the family Hylidae found in Central America from southern Mexico through Guatemala and northern El Salvador to central and northern Honduras. A major revision of the Hylidae moved an additional 21 species to this genus from the genus Hyla. The additional species moved to Plectrohyla were identified as the Hyla bistincta group, also called the Plectrohyla bistincta group; a separate group from the initial Plectrohyla guatemalensis group. This phylogenetic classification was later revised by moving the Plectrohyla bistincta group from the genus Plectrohyla into a new genus called Sarcohyla. Meanwhile, the guatemalensis group remained in Plectrohyla. They are called spikethumb because of the spike on their thumbs, which is called a prepollex. The genus name comes from the Greek word plēktron ("spur") and hyla.

<i>Charadrahyla</i> Genus of amphibians

Charadrahyla is a genus of frogs in the family Hylidae. It is endemic to tropical southern Mexico. The generic name was derived from Greek charadra ("ravine") and Hyla, in reference to the habits of these frogs. Accordingly, common name ravine treefrogs has been coined for the genus.

Megastomatohyla is a genus of frogs in the family Hylidae. They are endemic to the cloud forests of central Veracruz and Oaxaca, Mexico. All are rare species with restricted distributions. The generic name is derived from Greek mega (="large") and stem of the genitive stomatos (="mouth"), referring to the enlarged oral disc of the tadpoles, juxtaposed with Hyla, the genus in which the four Megastomatohyla species were previously placed. Common name large-mouthed treefrogs has been coined for this genus.

<i>Tlalocohyla</i> Genus of amphibians

Tlalocohyla is a genus of frogs in the family Hylidae, also known as rain treefrogs or Middle American yellow-bellied treefrogs. They occur in Middle America between Mexico and Costa Rica. This genus was created in 2005 following a major revision of the Hylidae. The five species in this genus were previously placed in the genus Hyla.

<i>Cruziohyla</i> Genus of amphibians

Cruziohyla is a genus of frogs in the subfamily Phyllomedusinae. They occur from Honduras in Central America south to the Amazon Basin in South America. This genus was erected in 2005 following a major revision of the Hylidae and fully reviewed in 2018. Species in this genus were previously placed in the genera Agalychnis or Phyllomedusa.

<i>Ecnomiohyla</i> Genus of amphibians

Ecnomiohyla, commonly known as fringe-limbed treefrogs or marvelous frogs, is a genus of frogs in the family Hylidae. This genus was erected in 2005 following a major revision of Hylidae. The ten original species in this genus were previously placed in the genus Hyla. The generic name Ecnomiohyla comes from Greek ecnomios and Hylas, the companion of Hercules.

<i>Bokermannohyla</i> Genus of amphibians

Bokermannohyla is a genus of frogs in the family Hylidae. It was erected in 2005 following a major revision of the Hylidae. Twenty-three species previously placed in the genus Hyla were moved to this genus named in honor of Werner Carlos Augusto Bokermann, Brazilian herpetologist. The genus is endemic to southern Brazil.

Bromeliohyla, sometimes known as the bromeliad treefrogs, is a genus of frogs in the family Hylidae. This genus was erected in 2022 following a major revision of the Hylidae. The original two species in this genus were previously placed in the genus Hyla. They are found in tropical southern Mexico, Belize, Guatemala, and northern Honduras.

<i>Dendropsophus</i> Genus of amphibians

Dendropsophus is a genus of frogs in the family Hylidae. They are distributed in Central and South America, from southern Mexico to northern Argentina and Uruguay. They are sometimes known under the common name Fitzinger neotropical treefrogs or yellow treefrogs

<i>Boana</i> Genus of amphibians

Boana is a genus of frogs in the family Hylidae. They are commonly known as gladiator frogs, gladiator treefrogs or Wagler Neotropical treefrogs. These frogs are distributed in the tropical Central and South America from Nicaragua to Argentina, as well as in the Caribbean.

<i>Dendropsophus marmoratus</i> Species of frog

Dendropsophus marmoratus is a species of frog in the family Hylidae. It is found in the Amazon rainforest and montane forests in the eastern piedmont, in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forests, intermittent freshwater marshes, and heavily degraded former forest. "Marmoratus" in Latin means "marble," perhaps referring to the dorsal coloring pattern. It is threatened by habitat loss.

<i>Itapotihyla</i> Genus of amphibians

Itapotihyla is a genus of frogs in the family Hylidae. It is monotypic, being represented by the single species Itapotihyla langsdorffii, commonly known as the ocellated treefrog. It is found in the Atlantic Forest biome of Brazil, with an isolated population in eastern Paraguay and adjacent Brazil and northeastern Argentina.

<span class="mw-page-title-main">Hylinae</span> Subfamily of amphibians

Hylinae is a large subfamily of "tree frogs", family Hylidae.

<span class="mw-page-title-main">Dendropsophini</span> Subfamily of amphibians

Dendropsophini is a tribe of small neotropical tree frogs in the subfamily Hylinae. They are distributed from southern Mexico, throughout Central America, and down South America to northern Argentina and Uruguay. Removed from the synonymy of Hylinae in 2016, this taxon was formerly considered its own subfamily before being reclassified as a tribe. As defined by Favovich et al. in 2005, the tribe Dendrosophini contains the members of three former subfamilies within the Hylidae prior to taxonomic rearrangement: Dendropsophinae, Pseudinae, and Scinaxinae.

<i>Pithecopus</i> Genus of amphibians

Pithecopus is a genus of frogs in the subfamily Phyllomedusinae. Species of the genus Pithecopus are found in tropical South America east of the Andes, from southern Venezuela to northern Argentina. Resurrected from the synonymy of Phyllomedusa in 2016, it corresponds to the former Phyllomedusa hypochondrialis group. Its sister group is Callimedusa.

<i>Rheohyla</i> Genus of amphibians

Rheohyla is a genus of frogs in the family Hylidae. As currently recognized, it is monotypic, containing only Rheohyla miotympanum, also known as the small-eared hyla or small-eared treefrog. However, the nominal species likely is a complex of more than one species. It is endemic to eastern and central Mexico. The generic name refers to streams, the breeding habitat of this frog. The specific name is derived from Greek meion, a diminutive prefix, together with Greek tympanon (='drum') and refers to the small tympanum.
