title: [Leaf beetles (Coleoptera: Chrysomelidae): mushroom body simplification in the course of progressive evolution of the family].
abstract: Members of different subfamilies of Chrysomelidae differ strongly in the degree of mushroom body development. The mushroom bodies are especially strongly developed (with the calyx in the form of large cups and double shafts of the peduncular apparatus) in the evolutionarily primitive subfamilies Sagrinae and Criocerinae, and considerably reduced in members of more evolved subfamilies, with the calyx region weakly developed and shafts of the peduncular apparatus fused together. It is suggested that this mushroom body reduction can be related to the closer connection of the head with the prothorax, which is found in the more evolved leaf beetle subfamilies.
