Evaluation of the fauna of Coleoptera Scarabaeoidea from the Calakmul Biosphere Reserve, in Campeche, Mexico

Species richness, abundance, and seasonal distribution of Coleoptera Scarabaeoidea were evaluated in the tropical forests located at Biosphere Reserve of Calakmul, Campeche, Mexico, from June 2012 to December 2013, by means of diurnal and nocturnal collections. One-thousand, two-hundred twelve specimens were obtained, representing 35 genera and 62 species of Melolonthinae, Rutelinae, Dynastinae, Cetoniinae, Scarabaeinae, Ceratocanthinae, Trogidae, y Passalidae of those 30 species are recorded for the first time for the state of Campeche. The richest genus was Phyllophaga with five species. The dominant species were Canthon vazquezae (28.3%), C. cyanellus (17.1%), Phyllophaga pallidicornis (11.9%), Enema endymion (7.8%), Megasoma elephas (3.2%), and Gymnetis chevolat (2.7%). The adult activities of 62 species were recorded during the complete year, but greatest abundance occurred during May to August. Scarab fauna of Calakmul is similar to that found at Tzucacab-Conkal, Yucatan (phytosaprophagous), and with Los Tuxtlas, Veracruz (copro-necrophagous) biosphere reserves of Mexico.
