Sarcohyla bistincta, also known as the Mexican fringe-limbed treefrog or Cope's streamside treefrog, is a species of frog in the family Hylidae. It is endemic to Mexico; it is widespread and occurs from southern Sinaloa and Durango southeastward to Veracruz and Oaxaca. [2] [3] The nominal Sarcohyla bistincta consists of several lineages that may eventually be described as distinct species. [1] [3]

Description

Males grow to a snout–vent length of 57 mm (2.2 in) and females to 60 mm (2.4 in). The head is wider than it is long; the snout is short and rounded. The tympanum is distinct but partly obscured by the supratympanic fold. The fingers are moderately long and slender and bear moderately large discs; only vestigial webbing is present. The toes are moderately long and slender too and bear discs that are slightly smaller than the finger ones. The toes are partially webbed. Skin is dorsally smooth but ventrally granular. Dorsal coloration varies from yellowish brown to dark brown (juveniles in some populations are greenish); the flanks are yellow to pale brownish tan with pattern of coarse dark brown to black anastomosing lines. The thighs are posteriorly blackish with bold yellow spots, with the yellow spotting also present on the anterior surface. The ventral surfaces are usually uniform pale yellow, but occasionally with sparse dark vermiform mottling, especially on throat and chest. The iris is deep reddish bronze. [4]

Habitat and conservation

Sarcohyla bistincta occurs in pine-oak and pine-fir forests [2] at elevations of 1,219–2,900 m (3,999–9,514 ft) above sea level [4] and in the associated streams. [2] They are often found sitting on large streamside boulders or on vegetation or exposed tree roots, but can also be found far from flowing water. [4] Breeding takes place in streams. It is threatened by habitat loss and potentially also by chytridiomycosis. Its range includes some protected areas. [2]

Charadrahyla nephila is a species of frog in the family Hylidae. It is endemic to Mexico and occurs in the Sierra de Juárez and Sierra Mixe in the northern Oaxacan highlands; there is also a questionable record from the Sierra de los Tuxtlas, Veracruz. Prior to its description, it was mixed with Hyla chaneque. The specific name nephila is derived from Greek nephos ("cloud") and philia ("fondness"), referring to the cloud forest habitat of this species. Common name Oaxacan cloud-forest treefrog has been coined for it.

Dendropsophus joannae is a species of frogs in the family Hylidae. It is known from the Pando Department, northern Bolivia, western Brazil, and Madre de Dios Region of southeastern Peru. It is similar to Dendropsophus leali but is smaller, has a shorter snout, more protuberant eyes, and more tuberculate dorsal skin. The specific name joannae honors Mrs. Jo Ann Oxley Foster, a BIOPAT patron supporting taxonomic research and nature conservation.

<i>Sarcohyla labeculata</i> Species of frog

Sarcohyla labeculata is a species of frog in the family Hylidae. It is endemic to the Sierra Mixe in Oaxaca, Mexico. This species was resurrected from synonymy of Sarcohyla bistincta in 2018, while at the same time bringing Sarcohyla calthula and Sarcohyla ephemera in its synonymy. Common name Mixe streamside treefrog has been proposed for this species, whereas the common names yellow-robed treefrog and Cerro Las Flores spikethumb frog referred to the former S. calthula and S. ephemera, respectively.

Sarcohyla celata, also known as the Oaxaca treefrog, is a species of frog in the family Hylidae. It is endemic to Mexico and only known from the Sierra de Juárez in northern Oaxaca. After having not been seen after 1984, it was feared that the species might be extinct. However, the species was rediscovered in field surveys during 2011–2014 and some subpopulations are at healthy levels.

Sarcohyla cyanomma, also known as the blue-eyed aquatic treefrog, is a species of frog in the family Hylidae. It is endemic to Mexico and only known from the northern slope of Cerro Pelón, in Sierra de Juárez in northern Oaxaca. It is feared that the species might be extinct.

Sarcohyla sabrina, also known as the Sierra Juarez treefrog, is a species of frog in the family Hylidae. It is endemic to the northern slopes of Sierra de Juárez in northern Oaxaca, Mexico. The specific name sabrina is Latin for river nymph and refers to the close association of this species with streams.

Sarcohyla siopela, also known as the voiceless treefrog or mute treefrog, is a species of frog in the family Hylidae.

It is endemic to Mexico and known from the Atlantic slopes of the Sierra Madre de Oaxaca in northern Oaxaca and adjacent central-western Veracruz. Before being described as a new species in 2000, it was mixed with Ptychohyla leonhardschultzei. The specific name zophodes is a Greek word meaning "dusky" or "gloomy" and refers to the distinctive dark coloration of the species as well as its cloud forest habitat. Common name gloomy mountain stream frog has been coined for it.

Scinax exiguus is a species of frog in the family Hylidae. It is found in the Gran Sabana of Venezuela and in the Roraima state of the adjacent northern Brazil, as far south as Boa Vista, Roraima. Common name Gran Sabana snouted treefrog has been coined for it.

<i>Pristimantis danae</i> Species of frog

<i>Sarcohyla</i> Genus of amphibians

Sarcohyla is a genus of frogs in the family Hylidae. It is endemic to Mexico and is found in the montane parts of the country between Durango in the north and Guerrero in the south. These frogs typically occur in pristine habitats along streams in pine-oak woodland at elevations between 1,500 and 3,100 m above sea level. The generic name is derived from the Greek sarkodes meaning "fleshy" in combination with Hylas and refers to the thick, glandular skin characteristic of most of the species in the genus.

<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.

Sarcohyla hapsa, the northern streamside tree frog, is a frog in the family Hylidae, endemic to Mexico.
