Anomaloglossus stepheni (common name: Stephen's rocket frog) is a species of frog in the family Aromobatidae. It is found in French Guiana and adjacent Suriname and Brazil. [2]
Colostethus stepheni is a small frog. Males measure about 14–17 millimetres (0.55–0.67 in) from snout to vent and females about 16–18 mm (0.63–0.71 in). Its general colour is some shade of brown and it has a dark stripe running down either side extending about half way along the body. There are bluish-white specks below this and on the toes. The male has a white or grey vocal sac and the female a pale throat. [3]
Colostethus stepheni occurs in French Guiana and adjacent Suriname [2] as well as in the Amazon rainforest of Brazil where it is widespread in the Adolfo Ducke Forest Reserve near the confluence of the Rio Negro and Solimões River. [3]
Colostethus stepheni is a diurnal, terrestrial species spending its life in forest litter where it forages on invertebrates such as termites, beetles and flies. [3] Breeding takes place in the rainy season. The male finds a suitable location and calls to attract a female. The nesting site is a boat-shaped curled up fallen leaf with another above acting as a roof. The female lays three to six eggs with gelatinous capsules inside the hollow leaf and remains at the nest for about an hour. After that she departs and the male returns and guards the eggs. He is territorial and drives off male intruders and seldom goes further than 20 centimetres (7.9 in) from the nest, continuing to remain nearby as the tadpoles develop. [4] Further females are encouraged to lay inside the nest which may come to have several developing clutches of eggs of different ages. The developing larvae are not transported to water, as is the case with the related dendrobatids, but complete their development on land. Metamorphosis into juvenile frogs occurs after about 31 days. [4]
Colostethus stepheni is listed as being of "Least Concern" in the IUCN Red List of Threatened Species. It is assumed to have a large population and wide range and the population appears to be stable. [1]
The blue poison dart frog or blue poison arrow frog is a poison dart frog found in the forests surrounded by the Sipaliwini Savanna, which is located in southern Suriname and adjacent far northern Brazil. D. tinctorius azureus is also known by its indigenous Tirio name, okopipi. Its scientific name comes from its azure (blue) color. While frequently considered a valid species in the past, recent authorities treat it as a variant of D. tinctorius.
The Bibron's toadlet or brown toadlet is a species of Australian ground-dwelling frog that, although having declined over much of its range, is widespread through most of New South Wales, Victoria, south-eastern Queensland and eastern South Australia, including Kangaroo Island.
Phyllomedusa bicolor, also known as the bicolour tree-frog, giant monkey frog, giant leaf frog, or waxy-monkey treefrog, is a species of leaf frog. It can be found in the Amazon basin of Brazil, Colombia, Bolivia, and Peru, and can also be found in the Guianan Region of Venezuela and the Guianas, and in Cerrado of the state of Maranhão in Brazil.
Allobates femoralis is a species of frog in the family Aromobatidae. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, and Suriname. Its natural habitat is tropical lowland forests.
Anomaloglossus baeobatrachus is a species of frog in the family Aromobatidae. It is found in northern Brazil south to Manaus, French Guiana, and Suriname; it is expected to occur eastern Guyana. It inhabits forest leaf-litter.
Anomaloglossus beebei is a species of frog in the family Aromobatidae. It is endemic to Guyana and only found on the Kaieteur Plateau, in the eastern edge of them Pacaraima Mountains. Recently, it has also been found on Mount Ayanganna.
Anomaloglossus degranvillei is a species of frog in the family Aromobatidae. It is known from French Guiana but is likely to occur also in Suriname and Brazil, and possibly in Guyana. It is named in honour of Jean-Jacques de Granville, a botanist from French Guiana.
Colostethus inguinalis is a species of frog in the family Dendrobatidae. It is endemic to northwestern and northcentral Colombia. Its vernacular name is common rocket frog, although this name can also refer to Colostethus panamansis that until 2004 was considered a junior synonym of Colostethus inguinalis. Much of the older literature on Colostethus inguinalis is actually about Colostethus panamansis.
Allobates marchesianus is a species of frog in the family Aromobatidae. It is found in the Amazon Basin in Brazil, Colombia, Ecuador, Peru, and Venezuela. However, this species might represent a cryptic species complex, where at least the populations from Venezuela belong to an undescribed species. Its natural habitats are secondary and old-growth tropical rainforests, where it lives on the forest floor. It is threatened by habitat loss.
Hyloxalus nexipus is a species of frog in the family Dendrobatidae. It is found on eastern slopes and foothills of the Andes from southeastern Ecuador south to the region of Yurimaguas in Peru.
Anomaloglossus tamacuarensis is a species of frog in the family Aromobatidae. It is found in the Sierra Tapirapecó in the Amazonas state of Venezuela as well as in the adjacent Amazonas state of Brazil.
Ameerega hahneli is a species of frog in the family Dendrobatidae. It is found in the Amazonian lowlands of Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana, French Guiana, and Suriname. It is named after Paul Hahnel, the collector of the type series.
Ameerega trivittata, formerly Epipedobates trivittatus, is a species of frog in the family Dendrobatidae commonly known as the three-striped poison frog. It is found in Bolivia, Brazil, Colombia, Guyana, Peru, Suriname, Venezuela, possibly Ecuador, and possibly French Guiana.
Dendropsophus microcephalus is a species of frog in the family Hylidae. It is found in southeastern Mexico, Central America, and northern South America in Colombia, Venezuela, Trinidad and Tobago, the Guianas, and northern Brazil. This widespread species might actually be a species complex. Its common names include yellow treefrog, small-headed treefrog, and yellow cricket treefrog.
Adelophryne gutturosa is a species of frogs in the family Eleutherodactylidae. It is found on the Guiana Shield from eastern Venezuela through Guyana to French Guiana and adjacent Brazil (Amapá), possibly extending to Suriname. Its type locality is Mount Roraima. Its local Spanish name is ranita guturosa.
The smoky jungle frog is a species of frog in the family Leptodactylidae. It is found in Bolivia, Brazil, Colombia, Ecuador, Costa Rica, Panama, French Guiana, and Peru. Its natural habitats are tropical and subtropical moist broadleaf forests, subtropical or tropical swamps, subtropical or tropical moist montane forest, rivers, freshwater marshes, intermittent freshwater marshes, and aquaculture ponds.
Leptodactylus rhodomystax is a species of frog in the family Leptodactylidae. It is found in the Guianas through northern and central Brazil to Amazonian Bolivia, Colombia, Peru, and Ecuador, and possibly in Venezuela where most if not all records represent misidentifications of Leptodactylus riveroi.
The Windward ditch frog or smooth-skinned ditch frog is a species of frog in the family Leptodactylidae. It is found in the Lesser Antilles, the Guianas, and in the northernmost Brazil (Roraima) and in Venezuela. The Lesser Antillean part of the range might be due to human introduction. In 2018, the species was recorded from Colombia for the first time.
Physalaemus ephippifer is a species of frog in the family Leptodactylidae. It is found in central and eastern Brazilian Amazonia, the Guianas, and southern Venezuela. It might not occur in French Guiana.
Anomaloglossus kaiei is a species of frogs in the family Aromobatidae, sometimes known as the Kaie rock frog. It is endemic to Guyana where it is known from the Kaieteur National Park and the Pacaraima Mountains. However, as it is found along the Guyana–Brazil border, it is also possibly present in Brazil. This frog shows maternal care: female frogs can provide tadpoles with trophic eggs.
