Distribution Asteroschema inornatum Koehler, 1906 is considered as an endemic species for the Northeast Atlantic (Paterson 1985). The species was recorded from the Reykjanes Ridge and Mid-Atlantic Ridge, southeast of the Charlie-Gibbs Fracture Zone (Martynov & Litvinova 2008), from 36°32.26′ N to 33°27.40′ W (Stöhr & Segonzac 2006), Rockall Trough (Gage et al. 1983), Bay of Biscay (Paterson 1985), Northwest Spain (Paterson 1985), off Azores (Koehler 1909; Paterson 1985) and off Madeira (Berry 1938; Smirnov et al. 2014). Its bathymetric distribution extends from 1300 (Martynov & Litvinova 2008) to 4140 m (Madsen 1951). We collected the species at six stations located off Western Sahara, between 1004 and 1593 m, normally associated with ...
