Trachycephalus quadrangulum, the Chocoan milk frog, is a species of frog in the family Hylidae. It is endemic to the Pacific slopes of the Andes in Ecuador and Peru. Scientists have seen it between 20 and 350 meters above sea level. [1] [2]
The adult male frog measures 53.4 to 76.9 mm in snout-vent length and the adult female frog 60.5 to 80.8 mm. The adult frog is brown or gray in color with a four-sided darker gray mark on its back. Its head is wider than it is long. [2]
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.
Trachycephalus is a genus of frogs, commonly known as the casque-headed tree frogs, in the family Hylidae. They are found in Mexico, Central America, and South America. In a recent revision, the seven species of the genus Phrynohyas were included in this genus, and Phrynohyas is now considered a synonym of Trachycephalus. These frogs inhabit the canopies of tropical rainforests, where they breed in tree cavities, and seldom, if ever, descend to the ground.
The Mission golden-eyed tree frog or Amazon milk frog is a large species of arboreal frog native to the Amazon Rainforest in South America. It is sometimes referred to as the blue milk frog. It was first discovered along the Maracanã River in Brazil. This species was previously within the genus Phrynohyas, which was recently synonymized with Trachycephalus.
Allobates marchesianus, also known as the dull rocket frog, 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.
Scinax boulengeri is a species of frog in the family Hylidae. It is found in Colombia, Costa Rica, Nicaragua, Panama, and possibly Honduras. Its natural habitats are subtropical or tropical moist lowland forests, intermittent freshwater marshes, pastureland, plantations, rural gardens, and urban areas. It has been found as high as 600 meters above sea level.
Trachycephalus lepidus is a species of frogs in the family Hylidae endemic to Brazil. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss. This species was previously within the genus Phrynohyas, which was recently synonymized with Trachycephalus.
Trachycephalus mesophaeus is a species of frog in the family Hylidae. It is endemic to eastern Brazil and occurs in the Atlantic Forest between Pernambuco and Rio Grande do Sul, extending inland to central Minas Gerais. It is found at elevations below 800 m (2,600 ft). Common name Porto Alegre golden-eyed treefrog has been coined for it, Porto Alegre being its type locality.
The veined tree frog, or common milk frog, is a species of frog in the family Hylidae. This species was previously within the genus Phrynohyas, which was recently synonymized with Trachycephalus . It is found in Central and South America. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, subtropical or tropical moist shrubland, subtropical or tropical dry lowland grassland, rivers, intermittent rivers, freshwater lakes, freshwater marshes, intermittent freshwater marshes, arable land, pastureland, plantations, rural gardens, urban areas, heavily degraded former forest, water storage areas, and ponds. The veined tree frog is nocturnal, and can typically be found in tree branches and in areas with large amounts of vegetation. This frog is one of several other tree frogs in the family Hylidae that secrete a toxic substance from their skin that produces extreme irritation and pain when in contact with mucosal membrane surfaces.
The Patzcuaro frog is a species of frog in the family Ranidae. Within the former, broadly defined genus Rana, it belongs to the Rana montezumae subgroup of the Rana pipiens complex. It is endemic to the Michoacán state, Mexico, where it is locally known as rana de Pátzcuaro. It occurs in Lake Pátzcuaro, Lake Cuitzeo, and the surrounding streams in Río de Morelia.
