ABSTRACT Shiny chafers of the tribe Anomalini are represented in Mesoamerica by 14 genera and 240 species, but revisions, keys to species and biological information are scarce, despite the fact that a number of species have been cited as pests of diverse cultures, mainly as part of the white grub guilds. Past studies on the taxonomy of these species offer many problems, because the genera were not adequately defined, the species usually offer character variability, genitalia were rarely described, and many authors do not agree with the status of the names. After phylogenetic studies with a generic sample of Anomalini from the world, Ramírez-Ponce and Morón proposed the revalidation of the genera Pachystethus Blanchard and Paranomala Casey, as well as the redefinition of the genera Anomala Samouelle and Callistethus Blanchard, because the representatives of these lineages have unique combinations of morphological characters and some synapomorphies are supporting adequately the nodes in the strict concensus tree obtained during such analysis. After the publication of the cited work, new evidences were found suggesting that other groups of species need to be separate in distinct genera from Paranomala while other taxa are part of the Paranomala clade. In the present review we provide brief nomenclatural history for each genus and synopsis of the phylogenetic hypothesis that support a new proposal for the classification of the genera represented in Mesoamerica. Diagnosis and comments on the distribution of the 14 genera are provided. Color photographs, illustrations of diagnostic characters and a key to genera are also included.
