Description

Voucher material, consisting of a series of fragments of arms and one partial disc. All material specimens form a monophyletic clade based on DNA. Arm processes (parasols) suggestive of Ophiotholia sp affinity. In NHM_076, arms are 0.31mm wide, with parasol-shaped processes of 0.19mm in length, parasols, 0.048mm in width (Fig. 21).

Genetic data for this taxa with new GenBank accession numbers are provided in Table 2

Diagnosis

Forms a unique monophyletic clade distinct from other AB01 specimens. Morphologically perhaps close to Ophiotholia but requires further sampling.

Ecology

Specimens recovered from two box cores, two specimens from each. Specimens from the same box cores genetically identical, so could be fragments of the same species.
