Tóm tắt

A taxonomic study of Hyalinoecia species based on the materials deposited in the Marine Biological Museum of the Chinese Academy of Sciences (MBMCAS) yielded two species: Hyalinoecia tubicola (Müller, 1776) and H. papillata Imajima, 1999. Both species were collected from the sandy bottoms in the northern South China Sea. Hyalinoecia tubicola is widely distributed from the coast of Guangdong Province southwards to the Xisha Islands. Hyalinoecia papillata is reported for the first time in the South China Sea. It differs from H. tubicola in having a prolonged, tongue-like prechaetal lobe with papillae along the lateral margins in the first parapodium (vs. auricular prechaetal lobe with smooth margins). The morphological description and illustration of both species are given.
