Checklist and distribution atlas of the scarabaeinae (Coleoptera: Scarabaeidae) of Costa Rica

Abstract

The 182 species of Scarabaeinae known to occur in Costa Rica are listed with synonymies included. We place Uroxys macrocularis Howden and Young as a synonym of U. Boneti Pereira and Halffter (new synonym); we also place Uroxys depressifrons Howden and Young as a synonym of U. pauliani Balthasar (new synonym). We conducted a mitochondrial DNA cytochrome oxidase I barcoding analysis in order to clarify some taxonomic uncertainties with Phanaeus pyrois Bates and Sulcophanaeus noctis (Bates). We elevate Phanaeus pyrois malyi Arnaud to Phanaeus malyi and revalidate Phanaeus excelsus Bates as valid species. We consider the species Dichotomius nevermanni Luederwaldt as incertae sedis. A Costa Rican distribution map is provided for all species except Dichotomius costaricensis, which is only known from a country record. We report, map, and estimate the spread of the invasive species Euoniticellus intermedius (Reiche) for Central America, from Chiapas to Costa Rica. Copyright © 2012 Magnolia Press .
