Description

Voucher material recovered from megacore sample, specimen with disc of 1cm diameter (Fig. 19). Additional material including juveniles recovered from box core and epibenthic sledge. Agrees with Amphioplus (Unioplus) daleus as detailed in ( Lyman 1879).

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 consistent with Amphioplus (Unioplus) daleus Lyman 1879. No genetic data for this species yet on GenBank. The type locality of A. daleus is Atlantic (36°44'S; 46°16'W; 4800m depth) and we use the tentative name Amphioplus cf. daleus for this material until we have a better understanding of genetic variation within the species including data from the type locality.

Ecology

Recovered from a range of sampling gears, NHM_447 recovered alive in top of multiple core tube.
