Voucher material NHM_374, width of disc 8.2mm, maximum width of specimen including arms 16.5mm (Fig. 12).

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

Diagnosis

Morphologically matches diagnosis of Styracaster paucispinus based on descriptions in Madsen 1961, Ludwig 1905 and material from the USNM collections with taxonomic adjustments from Mah 2015. Forms a unique monophyletic clade distinct from other AB01 specimens. No genetic matches on GenBank or Barcode of Life Database. The type material was collected in the Pacific Ocean at a similar depth to our material (8°30'S; 85°36'W, 4300m depth).
