New Records of Scarab Beetles from the State of Campeche, Mexico, with Comments on their Agricultural and Ecological Importance

Abstract. Six species of phytophagous scarab beetles (Scarabaeidae “Pleurosticti”) were first recorded from Campeche state, Mexico. The specimens were collected between August and November 2019 and belong to the following species: Euphoria yucateca (Bates, 1889) and Cotinis mutabilis (Gory and Percheron, 1833) (both Cetoniinae) and Cyclocephala melanocephala (Fabricius, 1775), Phileurus valgus (Olivier, 1789), Tomarus cuniculus (Fabricius, 1801), and Xyloryctes teuthras Bates, 1888 (all Dynastinae). The agricultural and ecological importance of each species is discussed, and its national distribution is given. The checklist of the Scarabaeidae “Pleurosticti” from Campeche was updated, consisting of 52 species, 24 genera, and five subfamilies. Resumen.
