Abstract
Con la finalidad de contribuir al conocimiento de la historia evolutiva y biogeográfica del género Goniomma se ha realizado una revisión morfológica de 147 individuos con base en 83 caracteres de las 7 especies endémicas de la Península Ibérica. Los análisis filogenéticos basados en parsimonia e inferencia bayesiana permitieron plantear una hipótesis filogenética basada en la morfología de estas hormigas. Para establecer hipótesis biogeográficas se realizaron un análisis panbiogeográfico y un análisis de parsimonia de endemismos (PAE). La filogenia obtenida se ajusta a la propuesta clásica que divide a este género en los grupos blanci y no-blanci y se asemeja a la filogenia molecular existente. Se identifican dos áreas de endemismo principales en la cuenca mediterránea para los géneros Goniomma y Oxyopomyrmex. La Península Ibérica se puede considerar como un centro de endemismo para Goniomma. El ancestro común a estos géneros podría haber colonizado el Mediterráneo desde regiones orientales. A mediados del Mioceno, se habrían diversificado, quedando el primero relegado a la Península Ibérica y el segundo distribuido más ampliamente por la cuenca mediterránea.
In order to contribute to the knowledge of the evolutionary and biogeographic history of the genus Goniomma, a morphological review of 147 individuals based on 83 characters of the 7 endemic species of the Iberian Peninsula has been carried out. Phylogenetic analyses based on parsimony and Bayesian inference allowed us to propose a phylogenetic hypothesis based on the morphology of these ants. To establish biogeographic hypotheses, a panbiogeographic analysis and a parsimony analysis of endemisms (PAE) were performed. The phylogeny obtained fits to the classical proposal that divides this genus into the blanci and non-blanci groups and resembles the existing molecular phylogeny. Two main areas of endemism are identified in the Mediterranean basin for the genera Goniomma and Oxyopomyrmex. The Iberian Peninsula can be considered as a centre of endemism for Goniomma. The common ancestor to these genera could have colonized the Mediterranean from eastern regions. In the Middle Miocene, they would have diversified, being the first relegated to the Iberian Peninsula, and the second distributed more widely by the Mediterranean basin.
