F). The rhinophoral sheath edges are capable of some contraction in living specimens. There are 713 rhinophoral lamellae. The notum is densely covered with mushroom-shaped or club-shaped tubercles on a short stalk. The larger tubercles dominate all over the notum, but a single irregular zigzag row of smaller tubercles appears in the mid-notal line. Some smaller tubercles are also scattered around various notal areas and at the edge of the notum. The rays of the spicules that extend from the bases of tubercles form a dense network that shines through the notum surface (

. The cerebral and pleural ganglia are well separated, the latter being somewhat smaller in size. The optic nerve is very short. The eyes are relatively large, with black pigment in all studied specimens. The pedal ganglia are smaller than the cerebrals, lay below them and are connected to them by very short connectives. The rhinophoral ganglia are rather irregular, globular or elongate. The buccal ganglia are slightly oval. Gastro-esophageal ganglia are present. Five pairs of cerebral nerves, two pleural and three pedal ones are detected.
