Four pairs of tentacular cirri with distinct cirrphores. Pair of black jaws with 5-6 teeth. Paragnaths on pharynx in distinct areas that are a mixture of conical, shield-shaped and p-bar paragnaths. Area I: one conical paragnath (Fig. 4A), II: 15–17 conical paragnaths in wedge shape, III: 22 conical paragnaths in three rows, IV: 27–32 conical paragnaths and p-bars in a closely spaced arc shape, V: one conical paragnath, VI: large shield-shaped bars and VII–VIII: 40 conical paragnaths and p-bars alternating in 2–4 rows.
