Lophophaena clevei, Trubovitz et al., 2020 , supplementary data 7.

Remarks. This species has a similar structure to Lophophaena clevei Petrushevskaya, 1971 , and we misidentified it as such in our previous study. However, L. amictoria differs from L. clevei in that it is larger overall, has a more globular cephalis shape, and a relatively inflated neck area.

Range. Middle Miocene—Late Pleistocene in the EEP ( Table 1 View TABLE 1 ). Early Miocene—Pleistocene in the Southern Ocean. Specimens from Lazarus and Pallant (1989) would indicate the range of this species extends back to the Early Oligocene.

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.
