Etymology The name of the genus Streptosyllis is formed by the prefix of Greek origin strepto-, meaning 'twisted' or 'curved', and the name of the genus Syllis Lamarck, 1818, the type of the family Syllidae, and refers probably to the body being strongly convex dorsally in the type species, Streptosyllis arenae Webster & Benedict, 1884.

Diagnosis (emended Maciolek, 2026). Palps fused at base, often turned ventrally and not visible dorsally, occasionally reduced to small papillae or may be large and rounded, visible dorsally; with small accessory papillae. Prostomial and tentacular cirri smooth or wrinkled, never articulated; anterior dorsal cirri smooth or indistinctly annulated, club-shaped to elongated; posterior dorsal cirri sometimes articulated, with glandular inclusions. Pygidium with one midventral and two dorsolateral anal cirri. Acicula with distinctly enlarged tips in variable number of parapodia from setiger 1 or 2. Compound setae with homogomph or heterogomph shafts, blades short falcigers or sometimes longer, spiniger-like; blades unidentate, bidentate or sub-bidentate; hoods on blades and shafts present or absent. Single type of dorsal simple setae present, with or without hoods; ventral simple setae present or absent in posteriormost setigers. [details]Etymology The name of the genus Streptosyllis is formed by the prefix of Greek origin strepto-, meaning 'twisted' or 'curved', and the name of the genus Syllis Lamarck, 1818, the type of the family Syllidae, and refers probably to the body being strongly convex dorsally in the type species, Streptosyllis arenae Webster & Benedict, 1884. [details]
Grammatical gender Syllis is feminine, the name of a female nymph, so Streptosyllis must also be feminine. Authors have thus assigned eight feminine suffix adjectival names. [details]
