Samoidae is a family of the harvestman infraorder Grassatores with about fifty described species.


The body length of members of this family ranges from about two to almost six millimeters. They are dull light brown to yellow or green yellow with darker mottling, and sometimes dark brown.


Samoidae from Polynesia, Melanesia, Australia, Mexico, the West Indies and Venezuela are all remarkably similar, while the species from Africa, Madagascar, Seychelles and Indonesia do at least in part not belong to this family.
