Systematic revision of Calligrapha Chevrolat (Coleoptera: Chrysomelidae) with pale spots on dark elytra and description of two new species.

In this work, a group of seven species of Calligrapha (Coleoptera: Chrysomelidae) with pale spots contrasting with dark background of elytra is revised and their distributions specified based on the material studied from sixteen museums. Among these species, two are new and formally described: C. pavimentata sp. nov. and C. zapoteca sp. nov. A pragmatic identification key is provided to identify these taxa and it is proposed that these species belong to four different evolutionary lineages.
