Remarks. Specimens observed in the EEP are within the range of those figured by Renaudie and Lazarus (2016) from the Southern Ocean. The authors of the species included two questionable identifications; one of which (fig. 9) we do not believe is within the range of this species, but it may be an aberrant specimen.

Range. Middle—Late Miocene in the EEP, but lower limit not determined with certainty ( Table 1 ). In the SO, this species was reported by Renaudie and Lazarus (2016) as rare in the Early Miocene, with one possible occurrence in the Middle Miocene.

Figures

FIGURE 1. Diagram illustrating the general skeletal morphology of Lophophaenidae, and terminology used in this manuscript. Dashed lines indicate spines that are not visible from the angle shown, as they extend into the skeleton. An example specimen of Lophophaena casperi n. sp. is included for comparison to the diagrams.
