These spines transition from curved pointed setae among capillaries to short curved blunt-tipped spines with knoblike tips in the very last setigers. No spines were observed in the notopodia. Because the neuropodial spines are limited to the very posteriormost setigers, they will not be observed in fragmented specimens. Therefore other characters will be required in order to identify the species. Other features of the body are similar to related species of

. These include the raised crest on the peristomium, the occurrence of lateral black pigment spots on the peristomium; the position of the paired dorsal tentacles on the posterior margin of the peristomium followed by the first pair of branchiae also on the peristomium and the generally elongated form of the body. In addition, the methyl green staining pattern in conjunction with the paired peristomial pigment spots readily differentiates this species from other cirratulids observed in these collections.
