Vasily I. Radashevsky and Hwey-Lian Hsieh (2000) This report discusses 5 species of the genus Polydora (Polychaeta: Spionidae) from the shallow waters of Taiwan and off mainland China. These include P. cf. agassizi Claparede, 1869, P. cornuta Bosc, 1802, and 3 new species: P. fusca, P. triglanda, and P. villosa. Polydora cf. agassizi inhabits mud tubes on the surface of a horseshoe crab; P. cornuta and P. fusca inhabit mud tubes on soft bottoms while P. villosa bores into skeletons of living corals. Polydora triglanda
is both a shell-borer and a tube- dweller, and no morphological
differences were found between individuals from the 2 habitats. Five
species are described and illustrated, and a key is provided for their
species with black bands on the palps, median antenna on the caruncle,
and needlelike spines on the posterior notopodia are reviewed, and
their morphological characteristics are compared.
Key words: Spionid polychaete, Polydora, Systematics, Morphology.
