Comparison: New material mostly corresponding with original description and paratype examined (Day 1957); in the paratype the last 12 chaetigers are abranchiate, falling within the range observed in the new material, posterior inferior companion chaetae are not mentioned in the description but are present in both the new material and the paratype, although they are present on fewer chaetigers in the latter.
The thorax contains 10 to 12 abranchiate setigers, each with a single dorsal ciliary band, capillary notochaetae, and a lateral tuft of cilia.
At the same time, we might have to reconsider the early proposal by Pruvot & Racovitza (1895:422) about the specific characters such as pigmentation pattern, length of antennae, their relative articulation, start of branchiae and their maximal filament number (size-dependent), type of pectinate chaetae, blade relative size features in compound falcigers, form and shape of the subacicular hooks, number of abranchiate posterior chaetigers, and number and length of anal cirri.
