Euhyas unicolor (Stejneger, 1904)
The dwarf coqui is a small frog with a grayish-brown back, a black-mask like face, and a series of light dots that follow through to the posterior of the frog. The females have a light line across the eyelids and usually have “white dots along the face, flanks, forelimbs, and thighs.” The Eleutherodactylus species do not have webbed feet. These frogs, especially the dwarf coqui, have individual, finger-like feet, with round, disc-like toes. E. coqui is often referred to as the “coqui,” which originates from its distinctive call. The “coqui” frogs are known for the unusual sounds they make. “The call of the dwarf coqui has been compared to the sound of a fingernail being dragged across the teeth of a comb or the winding of a watch.”
