. Preserved colour pale brown, no pigment or eyespots observed. Body shape unclear due to extent of dissection, but widest anteriorly, tapering to pygidium, tip missing. Radiolar crown with semicircular radiolar lobes bearing 2021 pairs of radioles. Radioles with wide radiolar flanges and long, tapered tips, approximately 23% of total radiole length. Pinnulae very fine, dense, longest in distal part of radiole, up to 0.25 × total length of radiole, then rapidly decreasing in length, terminating at or above lower margin of basal membrane. Radiolar eyes absent. Dorsal lips with slender, digitiform radiolar appendages, arising centrally, surrounded by enlarged, lobate ventral lips connected to radiolar lobes dorsally; pinnular appendages absent; ventral radiolar appendages absent; parallel lamellae and ventral sacs both absent. Anterior peristomial ring too damaged and degraded to describe. Notopodia as oval cushions, notochaetae all broken. Uncini not observed. Pygidial tip missing, tube not present.

The larger NMW.Z specimen also had a badly damaged crown, limiting observations on the crown and dorsal lips, and the remaining specimen was a juvenile, although in good condition. No attempt is therefore made here to re-validate the species. Although it is considered that the species is likely to be found to be valid in the future, to do so will require the examination and/or collection of new specimens from the
