Reexamination of the species has revealed further morphological features not previously described by Eliason, including prostomial and lamellar shape and the presence of sporadic tridentate hooded hooks.

. Both species possess distinctive transverse bands, particularly in the thoracic region, and have a similar prostomial shape. Whilst they can be distinguished in terms of presence/absence of thoracic superior dorsal processes, dentition of abdominal hooded hooks and lamellae shape, this morphological closeness is likely to have caused previous taxonomic confusions, particularly with juvenile specimens (see discussion).
