Sphaerodactylus genus of geckos from the Americas that are distinguished from other Gekkota by their small size, by their round, rather than vertical, eye pupils, and by each digit terminating in a single, round adhesive pad or scale, from which their name (Sphaero = round, dactylus = finger) is derived. All species in this genus are rather small, but two species, S. ariasae and S. parthenopion , are tiny, and – with a snout-vent length of about 1.6 cm (0.63 in)—the smallest reptiles in the world.
The following 105 species are recognized as being valid.
