A new fireworm species and a poorly described species of the genus Chloeia are described on the basis of specimens collected from Hong Kong. The new species, C. bimaculata sp. nov., is characterized by having two distinct mid-dorsal dark spots one behind the other on each segment. It can be distinguished from its sympatric species C. parva, which is characterized by having a mid-dorsal “Y”-shaped dark pigment on each segment. Chloeia bimaculata sp. nov. diverges from C. parva by 16.8% for the COI gene, 4.6% for the 16S rRNA gene and 0.6% for the 28S rRNA gene. Other Chloeia species with the corresponding gene sequences available in the GenBank show greater divergences.

Key words: Divergence, Polychaete, Taxonomy, South China Sea.
