Taxonomy Kroesche and Rouse (2025) state that: "Sirsoe shastae n. sp. was found to be a sister group to S. pleijeli n. sp., from which it is 8% divergent with COI. It can be distinguished from S. pleijeli n. sp. by its cirrophore on the ventral cirri of segment 3, shorter dorsal cirri, and straight compound chaetal blades. However, S. shastae n. sp. is most similar to S. grasslei morphologically and is only 4% divergent from it with COI. Sirsoe shastae n. sp. can be distinguished from S. grasslei in that it has fewer chaetae per parapodium, and the ventral cirri are much longer in proportion to the width. [details]
