Resumen
The panopeid crab Dyspanopeus sayi (Smith, 1869) is reported here from the Ebro Delta (Mediterranean coast
of the Iberian Peninsula). Originally endemic to the Atlantic coast of North America, D. sayi was involuntarily introduced
into Britain, France and the Netherlands, and into the Adriatic and Black Sea within the last thirty years. Here we provide
the first record of this species from the western Mediterranean Sea. Occurrences of ovigerous females at different localities
of the delta and in different years provide evidence that the population is well established. Mitochondrial DNA confirms
the identity of the species and indicates that the introduced population consists of at least three female lineages. The first
zoeal stage of D. sayi was obtained in the laboratory from an ovigerous female captured in August 2010 with embryos in an
advanced stage of development. The morphology of the zoea I is described here in detail and is similar to the one previously
reported for native populations.
