Setiger 1 is larger than following ones, bearing a pair of branchiae located dorsal to notochaetae. Setae of anterior segments include capillaries; long natatory capillaries are present on the two specimens here. The noto- and neurosetal fascicles of capillaries nearly merge laterally, with little space between them. Neuropodial acicular spines are present from setigers 21–25 (per

The two specimens, while incomplete, are well preserved and retain the form of the unusual pre-setal “head” that dominates the anterior end and provides ready recognition for this species. The narrow achaetous segments between the “head” and setigerous segments are as previously described.
