Plate 13, Figs. 3A – 6B.

unknown plagonid group E sp 16, Trubovitz et al., 2020, supplementary data 7.

Remarks. This species is unusual for its very strong ventral spine, which is as strong, and nearly as long, as the apical horn. The axobate and small cephalis indicate that this species belongs in Ceratocyrtis, but more specimens are needed before it can be adequately described.

Material examined. 4 specimens observed from samples 321-1337D-26H-3W, 142–144 (Late Miocene) and 321-1337D-23H- 6, 134–137cm (Late Miocene).

Range. Middle—lower Late Miocene, EEP (Table 1). Lower limit not determined.
