Abstract
    The species diversity of Syllidae (Annelida: Polychaeta) on different coastlines within
    the Mediterranean Basin was analysed, including along the Salento Peninsula (Italy), which is
    thought to play a crucial role as a crossroads between different biogeographic areas. Analysis of biogeography,
    the assignment of species into 6 bioclimatic categories, a novel method to assess intermatrix
    correlation significance and the correlation between species distribution, and some environmental
    variables provided relevant tools to investigate the influence of a suite of ecological and
    historical factors on syllid distribution. Data showed that Syllidae could be considered a useful taxon
    for biogeographic speculations, even though bioclimatic and environmental analyses appeared significantly
    more informative. The Salento Peninsula revealed an affinity with some eastern Mediterranean
    coastlines. Syllid distribution suggested the existence of an ‘Atlantism’ gradient, decreasing
    eastwards and possibly corresponding to a temperature gradient when bioclimatic categories were
    analysed. In contrast to previous results, the Eastern and Western Basins did not show great differences
    in species diversity. The observed differences could, in part, be due to an ‘author effect’, due to
    the differing taxonomic updating of the available faunistic lists. Syllidae were found to be effective
    faunistic and ecological indicators, able to characterize different areas inside the Mediterranean Sea;
    thus, the present results could be used to stimulate further research on different aspects of the family.
