Guerao, Guillermo Abelló, Pere Dyspanopeus sayi Alien species Mediterranean Ebro Delta mtDNA sequences Zoea Especies invasoras Mediterráneo Delta del Ebro Secuencias de mtADN mtDNA 7 pages, 4 figures, 3 tables [EN]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 [ES]Primera cita y evidencia de una población establecida del cangrejo americano Dyspanopeus sayi (Brachyura: Heterotremata: Panopeidae) en el Mediterráneo occidental. – Se informa de la presencia del cangrejo panopeido Dyspanopeus sayi (Smith, 1869) en el Delta del Ebro (costa mediterránea de la Península Ibérica). Originalmente endémica de la costa atlántica de América del Norte, D. sayi se introdujo en Gran Bretaña, Francia, los Países Bajos, en el Adriático y el Mar Negro en los últimos treinta años. En el presente trabajo se presenta el primer registro de esta especie en el Mediterráneo occidental. La presencia de hembras ovígeras en diferentes localidades del Delta del Ebro y en diferentes años evidencia que la población está bien establecida. El ADN mitocondrial confirma la identidad de la especie e indica que la población introducida consiste de por lo menos tres linajes de hembras. El primer estadio de zoea de D. sayi se obtuvo en el laboratorio a partir de una hembra ovígera capturada en agosto de 2010, con embriones en una etapa avanzada de desarrollo. La morfología de la zoea I se describe en detalle, siendo similar a descripciones anteriores de poblaciones oriundas Travel funds to CDS and students were made possible through an exchange program of the DAAD (D/03/40344) and the Spanish Ministerio de Ciencia y Tecnología – Acciones Integradas (HA2003-078), with José A. Cuesta as Spanish collaborator. Florian Gmeiner, Silke Reuschel and Lapo Ragionieri assisted during field collections in 2005 and 2006 respectively and students at the University of Regensburg helped with the molecular work. Financial support to GG (post-doctoral fellowship; INIA) was provided by the Ministry of Science and Research. The authors would like to thank Agustí Benito, fisherman of Sant Carles de la Ràpita for his collaboration in catching crabs.
