Eleutherodactylus angustidigitorum are small frogs with a maximum size of about
snout–vent length. The head is slightly narrower than the body and the snout is pointed. The
canthus rostralis is distinct while the
tympanum is small and indistinct. The digits have tapering tips; no webbing is present. Skin is smooth above apart from a few flattened and relatively indistinct pustules; the flanks and the venter are covered by large granules. Dorsal coloration is variable and may be nearly uniformly gray-black, reddish-brown with indistinct darker flecks and spots, deep brown, or brownish-gray with black spots. ==Habitat and conservation==
