Description

Males 26.8-32 mm SVL, females to 38 mm SVL. This species can be distinguished by a combination of small size; vertical (or nearly vertical) snout in profile; lack of vertical rostral keel; webbing between Fingers II-IV more than basal; abbreviated axillary membrane; smooth dorsal surfaces; males with tiny nuptial excrescences on prepollices as well as paired vocal slits and a single median subgular vocal sac; red iris; a broken rather than solid labial stripe and the absence of pale lateral stripes; and coloration/patterning (a lichenous dorsal pattern of olive and bright green and black blotching, on a brown background). Usually the dorsal patterning is quite distinct but occasionally will be less so. The venter is golden yellow. The outer forearm has a series of white dashes running from elbow to wrist. A white anal stripe is present. White-tipped tubercles are present below the vent. The plantar surfaces of the feet are unpigmented (McCranie and Wilson 2002; Wilson and McCranie 1985).

Tadpoles are long and slender with large, funnel-shaped ventral mouthparts. At stage 34, the tadpole has a total length of 42.7 mm, with the body being 12.4 mm and the tail 30.3 mm. The body is ovoid and depressed, as well as long and slender, with a robust tail musculature, low fins and rounded tail tip. The dorsal fin does not extend onto the body. The snout is rounded when viewed from above and acuminate in profile. Eyes are somewhat small, directed dorsolaterally, and are widely spaced. Nostrils are dorsolateral and are slightly closer to the eyes than to the tip of the snout. The mouth is large and funnel-shaped, directed ventrally, bordered with rows of tiny papillae and also with large conical papillae. Beaks are slender with the lower beak being V-shaped. Tadpoles have denticles 2/2, with the first upper row shorter than the second. First lower row is in the form of an inverted V and reduced, with a broad medial interruption. Second lower row of denticles is quite short. The spiracle is sinistral while the vent is dextral. The coloration of the tadpole in life is a pale yellowish olive green, with iridescent pale green spotting on the dorsum and tail. Iris is bright red.

The specific epithet soralia is a Greek word that refers to one of the means by which lichens can reproduce asexually. Lichen consist of algal cell clusters surrounded by fungal filaments; these groupings are called soredia, which develop inside the structures known as soralia and can be dispersed by wind from the soralia as powdery propagules. The bright green spots on Duellmanohyla soralia are said to resemble the "laminate soralia of a crustose lichen" (Wilson and McCranie 1985).
