Lophophaena sp. N

Plate 28, Figs. 9A–B .

Remarks. This species has a relatively narrow, thumb-shaped cephalis with at least four bladed, triangular horns near the apex of the cephalis. None of these horns appear to be related to the apical spine. The thorax is broad, and there is some indication of an axobate, though it is not fully preserved. This species differs from Antarctissa evanida Renaudie and Lazarus, 2013a in that the thorax does not flare outward as widely. Only one specimen was observed in our material, so more individuals will need to be examined to confirm the genus assignment and give this species a formal description.

Material examined. 1 specimen observed from sample 321-1337A-10H-2, 91–94cm (Early Pliocene).

Range. Early Pliocene, EEP ( Table 1 ).
