| Abstract: |
| Two species of Leodamas (Annelida, Orbiniidae) from China seas are described based on both material of the Marine Biological Museum (Chinese Academy of Sciences, Qingdao), and newly collected specimens. Leodamas robustus sp. n. is characterized by having uncini arranged in two short rows, anterior row with 3-5 uncini, increasing in size, with uncini on posterior chaetigers thicker, heavier and more curved than those on precedent chaetigers; posterior row with 2-5 uncini, thin and delicate, nearly the same size on all chaetigers, with 2-3 thin capillaries dorsally to two rows of uncini. Leodamas weizhouensis sp. n. is characterized by having delicate pocket-like membrane below and posterior to neuropodia, neuropodia of thoracic chaetigers with five dense rows of uncini. A key to all species of Leodamas from China seas is also provided. |
