Two new species of Syllis (Polychaeta: Syllidae) from South Africa, one of them viviparous, with remarks on larval development and vivipary
Two new species of South African Syllidae of the genus Syllis Lamarck, 1818 are described. Syllis unzima sp. nov. is characterized by having unidentate compound chaetae with long spines on margin, a characteristic colour pattern and its reproduction by vivipary. Vivipary is not common among the poly...
