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
