Sun, Yue; Sui, Jixing; Li, Xinzheng. (2018). A new species of Leodamas Kinberg, 1866 (Polychaeta: Orbiniidae) from the Yellow Sea and the East China Sea. Acta Oceanologica Sinica. 37(10): 130-135.
Based on polychaete specimens collected from coastal areas of China in 1959, a new species of the family Orbiniidae, Leodamas sinensis sp. nov. is described in the present paper. The new species can be distinguished from its cogeners by the combination of following characters: branchiae present from chaetiger 5; each thoracic neuropodial postchaetal lobe possessing broad tori, with a digital to triangular-shaped papilla at its midlength; 4 or 5 vertical rows of uncini and one posterior row of accompany capillaries in thoracic neuropodia; acicula present in both abdominal notopodia and neuropodia, slightly or distinctly projecting. A key to all known species of the genus is provided.
