Description
Eleutherodactylus mercedesae is known from two adult males reaching 40.1-49.5 mm SVL. Skin of dorsum is finely granular with ventral skin areolate. Irregular indistinct dorsolateral folds present. Tympanum is prominent and superficial, 33% diameter of eye. Snout is subacuminate in dorsal view and round in lateral profile. Canthus rostralis is sharp. Vomerine processes are large and nearly triangular, just medial and posterior to choanae. Head is equal to or wider than body. Upper eyelids with a few small tubercles. Two low to moderate postrictal tubercles are present posteroventrally to the tympanum. There are also scattered tubercles on the head (three or four on upper eyelid and one between eyes, two preinterocular and one on loreal surface, two behind eyes on a line between tympana). First finger is slightly shorter than second, fingers long with truncate tips and large pads. Lateral fringes on fingers present. Ulnar tubercles absent. Two metatarsal tubercles present, inner is oval and four times the size of the low outer. Toes have narrow lateral fringes with basal webbing. Toe tips truncate with broad pads. In life, its coloration is “medium brown dorsally with irregular, light green splotches (spots look like moss) and a few black marks; black eyestripe (canthal plus supratympanic stripe) and lip marks; limb iridescent coppery with green marks; thighs and sides of body speckled cream, green, and brownish black; ventrally pearl yellow, mottled brown; iris gold” (from field notes of M. S. Foster).
