Arachnocorys Haeckel 1860

Description

Arachnocorys ? sp.

Plate 3, Fig. 9.

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).
