About Epipedobates machalilla (Coloma, 1995)
Epipedobates machalilla (Coloma, 1995) is a small poison dart frog species with distinct size differences between males and females. Males measure 14.4 to 16 millimetres (0.57 to 0.63 inches) in snout–vent length, while females range from 15.0 to 17.6 millimetres (0.59 to 0.69 inches). This species has heads that are longer than wide, with a small tympanum. Forelimbs are moderate in length, and the fingers are unwebbed. Toes lack lateral fringes, and their terminal discs are expanded. The dorsal skin is dark-coffee, marked with a cream-yellow or cream-white stripe that develops pinkish tones toward the posterior end. Upper surfaces of the hind legs are light brown, while the forelegs are orange. Individual frogs have a gold iris and cream-colored ventral body surfaces. This species is endemic to western Ecuador, where it inhabits dry and low elevation forests. It is primarily found in the provinces of Azogues, Bolívar, El Oro, Guayas, Los Rios and Manabí, and has also been recorded in the Choco rainforest. It occurs at altitudes ranging from 10 to 515 metres (33 to 1,690 feet). Its populations have recently declined as a result of agricultural activity and logging. At least three protected areas within its range host the species: Parque Nacional Machalilla, Reserva Jouneche, and Reserva Ecológica Manglares Churute.
