''Nemastomoides'' is an extinct genus of harvestmen known from the Carboniferous fossil record. The genus is the only member of the family Nemastomoididae and contains three described species. ''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 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.〔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.〔 ==Species== * ''Nemastomoides elaveris'' Thevenin, 1901 * ''Nemastomoides longipes'' (Petrunkevitch, 1913) Not a harvestman, but a phalangiotarbid: * ''Nemastomoides depressus'' (Petrunkevitch, 1913) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nemastomoides」の詳細全文を読む スポンサード リンク
