HOLOTYPE: Cranidium, SMA 84034 (figured in Fortey, 1974: pl. 8, fig. 1). TYPE LOCALITY: Profilstranda, Olenidsletta Member, Valhallfonna Formation, Ny Friesland, Spitsbergen, Svalbard. STRATIGRAPHIC RANGE: Lower V 1b trilobite zone (Fortey, 1980), which coincides with the lower Oepikodus evae conodont zone and Pendograptus fruticosus zone within the upper Floian (fig. 1; see also Kröger et al., 2017). DIAGNOSIS: Cloacaspis ceryx species with relatively long (sag.) preglabellar field (0.08 – 0.19 length of glabella) and finely granular exoskeletal surface.
