A propos de cet article

With 557 named spider species in 202 genera and 58 families, Baltic amber represents the richest source of fossil spiders anywhere on the planet, with research describing this remarkable fossil fauna dating back more than 200 years. The identification of numerous species is problematic because many of the older descriptions are inadequate by current taxonomic standards. To compound this problem, many of the 'type' specimens on which the original descriptions were based have been lost. This has resulted in many dubious names, which have not hitherto been dealt with appropriately, making the dataset of Baltic amber spiders appear richer and more diverse than it actually is. Clearly, this will have consequences for any palaeoecological studies that choose to use these data. In addition, spider systematics is a highly dynamic subject, based almost entirely on extant taxa, with the latest changes (new families, genera and species, genus transfers etc.) documented in the World Spider Catalog. Until now, no similar comprehensive catalogue existed for the Baltic amber spider fauna, making it difficult for researchers to get a reliable estimate of the true palaeodiversity of the deposit or to trace the taxonomic and systematic history of any particular taxon. The catalogue presented here resolves these problems, updates the systematic placements of fossil taxa based on recent research on extant faunas, and also serves as a starting point for searching the literature when trying to identify a new Baltic amber spider specimen. It includes 95 new taxonomic contributions. This volume will be invaluable to anybody who curates a fossil collection including Baltic amber spiders and to those who identify their own material.
