Molecular Weevil Identification Project: A thoroughly curated barcode release of 1300 Western Palearctic weevil species (Coleoptera, Curculionoidea)

The Molecular Weevil Identification project (MWI) studies the systematics of Western Palearctic weevils (superfamily Curculionoidea) in an integrative taxonomic approach DNA barcoding, morphology and ecology. This barcode release provides almost 3600 curated CO1 sequences linked to morphological vouchers about 1300 weevil species. dataset is presented statistical distance tables as a Neighbour-Joining tree. Bayesian Inference trees are computed for subfamilies Cryptorhynchinae, Apioninae Ceutorhynchinae. Altogether, 18 unresolved issues discussed. A new primer set presented. Finally, we establish group-specific genetic distances many genera serve tool species delineation. These values statistically based on between "good species" their congeners. With this morphologically calibrated approach, could resolve most alpha-taxonomic questions within MWI project.
