Description

''Eleutherodactylus pinchoni'' is a small frog: males measure and females in snout–vent length; the smallest gravid female was . The snout is acuminate. The tympanum is visible and almost circular. The fingers are long, slender, and unwebbed, but have moderately well-developed discs. The toes are of moderate length and have vestigial webbing. The dorsum is very finely granular. Dorsal coloration is rich, dark wood brown, with variable patterning displaying four basic types. The most common pattern is a pair of relatively broad dorsal chevrons and—usually—a diagonal flank bar from each end of the second chevron into the groin. Some specimens also have two chevrons, but the posteriormost of which cuts off a middorsal patch of reddish-brown pigment in the sacral area. Instead of chevrons, some specimens have a pair of reddish-brown dorsolateral stripes. Finally, some frogs have a pair of dorsolateral lines as well as an irregular pale median dorsal stripe. The ventrum is orange, but this color may be almost completely obscured by overlying dark brown mottling, blotches, or stipples.
