Width measurements are less than those recorded by Mohammed, although Mohammed included the parapodia within his measurements. Chaetiger 3 on both sides, chaetigers 7 and 20 on the left, and the left neuropodium of chaetiger 9 have been previously dissected (presumably by Mohammed, as these are figured in the original description).

Proboscis everted (not fully), heart–shaped; longitudinally ridged inferiorly, appearing smooth superiorly but with light transverse ridging (partially obscured as proboscis tip not everted). Palps arising ventrolaterally from base of prostomium, fairly robust, reaching around chaetiger 18, non–papillated region reaching chaetiger 3. Papillae short proximally, increasing in size, papillae long distally. Initially 3 rows of papillae either side of inconspicuous ventral groove, distally 2 rows.
