AB  - <i>Streblospio gynobranchiata</i>, a new species of spionid polychaete, is described from Florida and the Gulf of Mexico. This species is distinguished by the presence of strap-like branchiae, beneath which larvae are brooded, in the genital body region of the females. Data from experimental crosses conducted in the laboratory are presented that indicate incipient reproductive isolation between <i>S. gynobranchiata</i> from Florida and <i>S. benedicti</i> from North Carolina and California. The spermatophores produced by males of <i>S. gynobranchiata</i> and <i>S. benedicti</i> are described for the first time. Morphological, developmental, and reproductive characteristics are used in combination to construct a cladogram that suggests possible phylogenetic relationships between known species in the genus <i>Streblospio</i>.
