Arachnocorys sp. 4 , Trubovitz et al., 2020, supplementary data 7.

Remarks. This species has a narrow thorax, with large pores at the top of thorax. These gaps suggest it could be Arachnocorys , but the overall shape of the skeleton is also consistent with Lophophaena . Few specimens were documented in Trubovitz et al. (2020), so further study is needed before this species can be confidently described.

Material examined. 9 specimens from samples 321-1337A-7H- 6, 104–107cm (Early Pliocene), 321-1337A-4H-2, 16–19cm (Middle Pleistocene), 321-1337A-3H- 2, 103–106cm (Middle Pleistocene), 321-1337A-2H-3, 76– 79cm (Late Pleistocene), and 321-1337D-1H-1, 0–3cm (Recent).

Range. Early Pliocene—Recent in the EEP, so far as known ( Table 1 ).
