Abstract
The capitellid genus Leiocapitella is characterized by the possession of anterior 12–16 chaetigers exclusively with capillaries and the following 1–2 transitional chaetigers with notopodial capillaries and neuropodial hooded hooks. A new species was obtained from the continental shelf of the East China Sea, and is identified herein as Leiocapitella fujianensis. The new species differs from the other four described species by the number and location of transitional chaetigers, the dentition of abdominal hooks, and the methyl green stain on thorax. A key to all Leiocapitella species is provided in this paper.
