Ceratocyrtis sp. F

Plate 12, Figs. 9A –11.

Ceratocyrtis sp 10, Trubovitz et al., 2020, supplementary data 7.

Remarks. This species typically has a slightly thorny cephalis and thorax, with small, regular pores, and one slight dimple on thorax. The cephalis exhibits one main forked spine. This species is very similar to Ceratocyrtis sp. E (pl. 13, figs. 7A–8), but differs in that the primary cephalic horn is forked.
