This edition of the database (prerelease version) needs registration and includes curtailed version of great work which is devoted to taxonomy, fauna, ecology and biology of all Palearctic representatives (398 species) in the largest genus of Leaf-beetles family. Due to the database is acquainted with complete version of the work and advertises it, you can find complete check-list of taxons and synonyms, but only some of them are completely described and illustrated.

You can test possibility of the key (the Key section) on instance of these taxons (29 species). This database edition includes all information about host-plants, body-sizes, references for each species. But information about detailed Palearctic distribution, ecology and biology, taxonomy is curtailed as a rule. In the complete version search by means some filters are available.
