Welcome to Carabidae of the World project htttp://carabidae.org it is a constantly updated taxonomic database with about 100 international contributors and participants, more 20.000 high resolution images of more then 15000 species of ground beetles for around the world!

Circular cladogram representing the maximum likelihood phylogeny inferred in IQ-TREE using the Comp_DT dataset comprising nine gene fragments and about 11kb of molecular data. The branch lengths have been modified to ease the visualization of relationships

Stop describing fake species!
Under each stone does not live another species new to science.
If you follow the logic of some "specialists", then Homo sapiens can be divided into several species, and dogs into several genera.

Recently was published excellent paper of Fominykh, Zamotajlov, Khomitskiy & Titarenko, 2020 "Contribution to the knowledge of Carabus (Lipaster) stjernvalli Mannerheim, 1830 in the Caucasus, with description of two new subspecies (Coleoptera: Carabidae: Carabini)", "dedicated to study of variability of species Carabus (Lipaster) stjernvalli", although, in fact, the sole purpose of the work was to describe new taxa in order to sell their Paratypes.
But, this work perfectly proves that there are no differences between the previously described subspecies, as well as the newly described ones. New synonymy in the species Carabus (Lipaster) stjernvalli proposed here 12.2.2020 by A. Anichtchenko

I'm looking for Cicindelinae (especially Nearctic and Australian), Cychrini (Nearctic and from China) and Carabus from China. Quality of material is not important. For exchange I can offer huge quantity of material of Coleoptera worldwide, of all families except Carabidae. For detales please contact Alexander Anichtchenko beetl2000(*)mail.ru
