The Nemastomoididae are a family of fossil harvestmen with three described species from the Carboniferous. "Nemastomoides elaveris" was found in the Coal Measures of Commentry in northern France, together with "Eotrogulus fayoli".

Alexander Petrunkevitch described two fossil harvestmen from Mazon Creek, Illinois, USA, in 1913 in the genus "Protopilio", but later synomymized the two with the genus "Nemastomoides".

While "N. longipes" is a harvestman with long legs and a segmented oval body, "N. depressus" is in reality not a harvestman, but a poorly preserved phalangiotarbid.aut|Dunlop, Jason A. (2007): Paleontology. In: Pinto-da-Rocha "et al." 2007: 255]

While the Nemastomoididae are currently included in the harvestman suborder Dyspnoi, they look more like Eupnoi.
