Edalorhina perezi (Perez's snouted frog) is a species of frog in the family Leptodactylidae. It is one of the only two species in the genus Edalorhina in the family Leptodactylidae. This species is diurnal and terrestrial. During mating season both female and male frogs gather around treefall pools. It is found in Brazil, Colombia, Ecuador, and Peru, and possibly Bolivia. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and freshwater marshes. The species listed as least concern on the IUCN Red List and the population is stable. Description General Identification Adult Similar to many other frog species, female Perez’s snouted frogs (E. perezi) are larger than males. Males are on average 28-36 mm in size and the females are 35-40 mm. The general color of this frog is very similar to leaf litter, which is a cryptic color protection in its habitat. Dorsum skin color is brown and there are usually many random dark brown markings on the back, such as tubercles and longitudinal ridges. Distinct characteristics of this frog include its eyelids, which have conical tubercles growing around the edge, a vertical ridge between the eyes, and the underdeveloped vomerine teeth. The iris is bronze and has some radiating grayish-brown lines. The body is a concaved shape with the spine dips down, differentiating the species from its sister taxon. The ventral side is smooth and white, with large black dots at lateral and posterior areas. The limbs are barred and the groin has an orange color decorated with black dots. It has unwebbed toes as a terrestrial frog species, and the first and second toes are of equal length. The snout of this frog is pointed, but the mouth part of the other species E. nasuta in the same genus looks sharper because of a long, fleshy proboscis. This sister species also differs from E. perezi by having smaller eyelid tubercles. A similar species from another genus is "Physalaemus Petersi", which also has an orange groin, but this species doesn’t has eyelid tubercles and has a different black and white belly pattern. "P. petersi" also has a gray throat and chest that is also different from the Perez’s snouted frog.There are several small but marked differences between them and their closely related species. Offspring Tadpoles in genus Edalorhina, which is the genus of the Perez’s snouted frog, are generally similar to
