Ceratocyrtis sp 5 cf, Trubovitz et al., 2020, supplementary data 7.

Remarks. This species has a thorax that tends to taper slightly towards the base, similar to Ceratocyrtis sp. C (pl. 13, figs. 1A–2B). However, it is much smaller in overall size and has relatively larger pores and a proportionally smaller cephalis.

Material examined. 9 specimens observed from samples 321-1337D-23H- 6, 134–137cm (Late Miocene), 321-1337A-18H-6, 77–80cm (Late Miocene), 321-1337A-10H-2, 91–94cm (Early Pliocene), 321-1337A-7H- 6, 104–107cm (Early Pliocene), 321-1337A-6H-3, 29–32cm (Late Pliocene), and 321-1337A-5H-5, 11–14cm (Late Pliocene).

Range. Late Miocene—Late Pliocene in the EEP ( Table 1 ).
