Plate 35, Figs. 7A – 10B .

unknown plagonid group C sp 50, Trubovitz et al., 2020, supplementary data 7.

Remarks. This species is large, and has many strong cephalic spines, differentiating it from Lophophaena gozui n. sp. (pl. 31, figs. 1A–6), which only has two spines. The thorax of this species is very thorny around the shoulder area and about three times as broad as the cephalis.

Material examined. 5 specimens observed from samples 321-1337A-14H-7, 39–42cm (Late Miocene), 321- 1337A-12H-5, 23–26cm (Late Miocene), 321-1337A-7H- 6, 104–107cm (Early Pliocene), and 321-1337A-5H-5, 11–14cm (Late Pliocene),

Range. Upper Late Miocene—Latest Pliocene, EEP ( Table 1 ).
