Fig 7A–7E View Fig 7

Material. NRM X12707; NRM X12708.

Description. Shell reniform in lateral view; elliptical in dorso-ventral view. Radial ridges well-developed; 31–33 in number, flat-crested or blade-shaped, 3–7 μm wide. Concentric ridges generally weak, slightly more developed at venter and/or dorsum. On one specimen, concentric ridges incompletely developed at lateral sides, rarely reaching anterior and posterior. Back distinct. Collar-shaped margin and caudal spine are damaged.

Comparison. This species is distinguished from others by the predominance of radial ridges.

Dimensions. Length 365(383)400 μm; width 160(164)167 μm (two specimens).

Remarks. One specimen with both radial and concentric ridges forms a partially reticulate ornamentation ( Fig 7C–7E View Fig 7 ). However, the shell surface is unambiguously dominated by radial ridges, thus favouring assignment to Kuqaia radiata .

Occurrence, unit and age. 46.97– 46.07 m, Kävlinge BH-928; Katslösa Member, Rya Formation; Pliensbachian.
