Symphytognathidae is a family of spiders with 90[1] described species in eight genera. Most species inhabit the New World tropics and Oceania.[2]
The species Patu digua is considered to be one of the smallest spiders in the world with a body size of 0.37 millimetres (0.015 in).[3]
Distribution

Exceptions include some Anapistula species, with A. benoiti and A. caecula found in Africa, A. ishikawai found in Japan, and A. jerai found in Southeast Asia. Symphytognatha imbulunga is also found in Africa. [2]
