Three species of nereidids collected from various ecological surveys conducted on coasts of west central and northeastern of Taiwan are studied. Each species represents a genus in the subfamily Nereidinae Blainville, 1818 not previously reported from Taiwan: Composetia Hartmann-Schro¨der, 1985, Eunereis Malmgren, 1865 and Nectoneanthes Sato, 2013. Composetia budaiensis n. sp. can be distinguished from congeners by having 2–5 and 17–27 paragnaths on Areas I & III of the pharynx, respectively. Eunereis shichengensis n. sp. differs from congeners by having one shield-shaped bar on Area VI of the pharynx. The generic diagnosis of Eunereis is emended slightly to include short neuropodial heterogomph falcigers in E . shichengensis n. sp. and three other congeners. Nectoneanthes species examined in the present study showed a continuous broad band of numerous paragnaths on the oral ring of the pharynx, which agrees with the unique character of N . uchiwa Sato, 2013 and represents the first record of the species for Taiwan. A key to all known species to Eunereis are provided. [author email: pwhsueh@dragon.nchu.edu.tw]
