Microstigmatidae is a small family of spiders with about 38 described species in eleven genera. They are small ground-dwelling and free-living spiders that make little use of silk.^[1]

The family was removed from the family Dipluridae in 1981.^[2] The subfamily Pseudonemesiinae from the family Ctenizidae was also transferred into the Microstigmatidae.^[3]
