S. hirsuta (Hansen, 1882) n. comb. Arctic and subarctic – Median chaetigers with notochaetae longer than body width. 3 3(2) Median neurochaetae with distal articles barely longer than wide, tips straight; gonopodial lobes present. 4 – Median neurochaetae with most articles markedly longer than wide; no gonopodial lobes. 5 4(3) Gonopodial lobes dark (papillae core and tip blackish); body papillae thick, digitate (body often grayish). S. normani (McIntosh, 1908) n. comb. Arctic and subarctic – Gonopodial lobes pale; body papillae thin, filiform (body often pale).

Central eastern Pacific 6(5) Median chaetigers neurochaetae with basal anchylosed region 1/2–1/3 chaetal length, medial and distal regions with articles 4–5 times longer than wide, barely shorter with a very slight reduction distally. S. ilys n. sp. Central eastern Pacific – Median chaetigers neurochaetae with basal anchylosed region 1/5–1/6 chaetal length, medial and distal regions with articles about twice longer than wide, progressively smaller. S. micans (Fauchald, 1972) n. comb. Central eastern Pacific 7(1) Neurochaetal tips falcate. 8 – Neurochaetal tips straight. 9 8(7) Median chaetigers with notochaetae half as long as body width; median neuropodia with five neurochaetae per bundle; body wall and chaetae yellowish.
