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, United States, in 1913 in the genus Protopilio, but later synonymized 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.[1]
While the Nemastomoididae are currently included in the harvestman suborder Dyspnoi, they look more like Eupnoi.[1]
