 The ten original species in this genus ("E. rabborum" and "E. sukia" are later discoveries) were previously placed in the genus "Hyla".The generic name "Ecnomiohyla" comes from Greek "ecnomios" ("marvelous" or "unusual") and Hylas, the companion of Hercules.Members of "Ecnomiohyla" are moderately sized to very large frogs with distinctive scalloped fringes of skin on the outer edges of their limbs and relatively immense hands and feet.
