Chiasmocleis is a genus of microhylid frogs. They are found in tropical South America north and east of the Andes. Their common name is humming frogs or silent frogs, the latter referring to the formerly recognized Syncope.
The pleasing poison frog is a species of frog in the family Dendrobatidae endemic to Peru. The specific name bassleri honors Harvey Bassler, an American geologist and paleontologist.
Proceratophrys concavitympanum is a species of frog in the family Odontophrynidae. It is endemic to Brazil and known from Rondônia, northwestern Mato Grosso, Pará, and Tocantins. It is the only Proceratophrys found in the Amazon rainforest.
Choerophryne brunhildae is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is known from the Adelbert Range, the Bewani Mountains, and the Hunstein Mountains.
Hamptophryne alios is a species of frog in the family Microhylidae. It is known from three localities in the southwestern Amazon Basin of Bolivia, Brazil, and Peru. This species used to constitute the monotypic genus Altigius, but molecular phylogenetic analyses have shown it to be close relative of the then-monotypic Hamptophryne, and the two genera have been merged.
Arcovomer is a genus of frogs in the family Microhylidae. It is monotypic, being represented by the single species Arcovomer passarellii, commonly known as Passarelli's frog. It is endemic to south-eastern Brazil and found in Espírito Santo, Rio de Janeiro, and São Paulo states. Frogs from Espírito Santo may represent another, undescribed species. The name honours Antonio Passarelli who collected the holotype.
Chiasmocleis alagoana is a species of frogs in the family Microhylidae. It is endemic to remnants of the Atlantic rainforest in the states of Alagoas, Paraíba, and Pernambuco in north-eastern Brazil. The specific name alagoana refers to Alagoas, the state where this species was first found.
Chiasmocleis anatipes is a species of frog in the family Microhylidae. As currently known, it is endemic to northeastern Ecuador, but it is likely to occur also in adjacent parts of Peru and perhaps Colombia too. The specific name anatipes refers to the "duck-like" feet of this frog, characterized by extensive webbing between the toes. Common name Santa Cecilia humming frog has been proposed for this species.
Chiasmocleis cordeiroi is a species of frog in the family Microhylidae. It is endemic to Bahia in eastern Brazil. It is known from Camamu, its type locality, and from few other localities on both sides of the De Contas River. The specific name cordeiroi honors Paulo Henrique Chaves Cordeiro, a Brazilian biologist. Common name Cordeiro's humming frog has been coined for this species.
Chiasmocleis crucis is a species of frog in the family Microhylidae. It is endemic to Bahia in eastern Brazil. It is known from Camamu, its type locality, and from the Serra Bonita Private Reserve of Natural Heritage in Camacan/Pau Brasil. The specific name crucis honors Carlos Alberto Gonçalves da Cruz, a Brazilian herpetologist.
Chiasmocleis hudsoni, also known as Hudson's humming frog, is a species of frog in the family Microhylidae. It is found in French Guiana, Suriname, Guyana, Guianan Venezuela, Colombia (Amazonas), and Amazonian Brazil. Chiasmocleis jimi has been included in this species but the most recent genetic analyses support its recognition as a distinct species; both species might include further distinct lineages that warrant recognition as species.
Chiasmocleis ventrimaculata, also known as the dotted humming frog, is a species of frog in the family Microhylidae. It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru. Its natural habitats are subtropical or tropical moist lowland forests, swamps, and intermittent freshwater marshes.
Cophixalus zweifeli is a species of frog in the family Microhylidae. It is endemic to northern Queensland, Australia, and only known from the area of its type locality in the Cape Melville National Park. The species was named to honour American herpetologist Richard G. Zweifel. Common name Zweifel's frog has been coined for it. It is one of the five northeast Australian Cophixalus species that are specialized in boulder field habitats.
Stereocyclops histrio is a species of frog in the family Microhylidae. It is endemic to the northeastern Bahia state of Brazil where it occurs in remnants of the Atlantic forest. After the holotype was collected in 1944, the species went unrecorded until a population was found in the Una Biological Reserve and its surroundings in 1999. It is now known from four locations. Common name Bahia yellow frog has been coined for it, perhaps in reference to the bright lemon yellow coloration of the holotype. It was the only species in the genus Hyophryne until 2012 when molecular data demonstrated that it is nested within Stereocyclops species.
Myersiella is a genus of frogs in the family Microhylidae. It is monotypic, being represented by the single species, Myersiella microps. It is endemic to southeastern Brazil and occurs in Espírito Santo, Rio de Janeiro, southeastern Minas Gerais, and southeastern São Paulo state. The genus name honors George S. Myers. The genus is sometimes known as the elongated frogs, while the sole species is known as Rio elongated frog.
Uperodon nagaoi, also known as the Nagao's pug-snout frog or Nagao's globular frog, is a species of frogs in the family Microhylidae. It is endemic to Sri Lanka and is known from the Central, Sabaragamuwa, Southern, and Western Provinces. The specific name nagaoi honours Eijiro Nagao, president of Marusan Securities who, through the Nagao Environmental Foundation, has supported research on Sri Lankan amphibians.
Stereocyclops incrassatus is a species of frog in the family Microhylidae. It is endemic to eastern Brazil and is known from Pernambuco and Alagoas in the north and then southward through Bahia to Minas Gerais and Espírito Santo. Earlier records from São Paulo state are now recognized as Stereocyclops parkeri. Common name Brazilian dumpy frog has been coined for this species.
Chiasmocleis antenori, also known as the Ecuador silent frog, is a species of frog in the family Microhylidae. It is found in eastern Ecuador, eastern Peru, and western Brazil (Acre). It might be a species complex.
Chiasmocleis quilombola is a species of frogs in the family Microhylidae. It is endemic to southeastern Brazil and found between the Doce River and the Mucuri River in the state of Espírito Santo. The specific name quilombola is derived from quilombo, the name for a Brazilian community founded by escaped slaves.
Chiasmocleis lacrimae, the central humming frog, is a frog in the family Microhylidae. It is endemic to Brazil, where it lives in lowland forest habitats.
