AB  - A new species of Polygordiidae, <i>Polygordius jouinae</i> sp. nov., along with its distribution, habitat, and reproduction is described. <i>Polygordius jouinae</i> sp. nov., the first North American <i>Polygordius</i>, is a dominant member of macrofaunal communities on the inner continental shelf, and in bays and harbours from Massachusetts to southern New Jersey. It is distinguished from most other <i>Polygordius</i> species by its non-inflated, heavily ciliated pygidium, absence of pygidial glands, and a conical (rather than rounded) prostomium. The 18S SSU rDNA from <i>P. jouinae</i> sp. nov. was sequenced and represents the first named <i>Polygordius</i> species with a DNA reference in GenBank. Spearman rank correlation of sediment grain size with density of <i>P. jouinae</i> sp. nov. at a New Jersey site showed that density was significantly (<i>P</i><0.05; N=92) positively correlated with the proportion of medium to very coarse sand and negatively correlated with the fine sand fractions. Ecologically, <i>P. jouinae</i> sp. nov. is an important macrofaunal species given its widespread distribution and its fidelity for coarse sand habitats. Thus, its relative abundance may be useful as an indicator of changing sedimentary conditions.
