Eresus Cinnaberinus

Eresus cinnaberinus (formerly Eresus niger), of the family Eresidae, is commonly called the Ladybird Spider. It is native to Europe.

The taxon "Eresus cinnaberinus" is considered a nomen dubium by some authors, the specimens having been divided into the species E. kollari, E. sandaliatus and E. moravicus. The three species differ in size, colour pattern, shape of prosoma and copulatory organs, and habitat, with no morphologically intermediate forms. As eastern and western E. kollari are genetically different, with the eastern form likely a hybrid between "pure" E. kollari and E. moravicus, it is possible that later revisions will partition it into additional species.
