Dentatisyllis mangalis, a new viviparous species of syllid polychaete, is described from mangrove and adjacent shallow-water habitats of Twin Cays, Belize. The new species is distinguished by a combination of short dorsal cirri with only a few articles and compound falcigers with long tapering blades bearing bifid tips. Analysis of meristic and linear characters used in classical syllid taxonomy revealed that the mean number of articles per dorsal cirrus per individual increases only slightly with increasing body length (growth); proventricle length increases linearly with body length; and the ratio of proventricle length to width is relatively independent of body length. Furthermore, overall growth is accomplished more by the addition of segments than the elongation of existing ones. The genus diagnosis is emended to include the presence of nuchal organs.
