Epedanidae is a family of the harvestman infraorder Grassatores with about 200 described species. They are the sister group of the Gonyleptoidea. The Epedanidae are endemic to Asia. The subfamily Dibuninae forms the predominant harvestman fauna of the Philippines. The other three subfamilies are more predominant in Indonesia, Malaysia and Thailand, and some are found in Burma and Nepal. Some species occur outside this region, in India, China, Vietnam and Japan. One species is even endemic to New Guinea. The oldest fossils of the family are known from the Cenomanian aged Burmese amber of Myanmar.
