Silverstoneia are small frogs, with adult size <22 mm (0.87 in) in snout–vent length.[4] They have brown, cryptic colouration in the dorsum. They have a pale oblique lateral stripe as well as pale ventrolateral stripe, but no pale dorsolateral stripe (except for some populations of Silverstoneia flotator in Costa Rica). Dorsal skin texture is granular posteriorly.[1]
