ALCAZAR-RUIZ, José Antonio; MORON-RIOS, Alejandro  y  MORON, Miguel Angel. Fauna de coleoptera Melolonthidae de Villa Las Rosas, Chiapas, México. Acta Zool. Mex [online]. 2003, n.88, pp.59-86. ISSN 2448-8445.

A study of the nocturnal Melolonthidae beetle fauna of Villa Las Rosas, Chiapas, México is presented. Data were obtained during 1999-2000 with 103 nights of collecting effort at lights near the borders of subdeciduos tropical forest and pine-oak forest, located at 1,240 m of altitude. Records of 3 subfamilies, 9 tribes and 50 species of the genera Diplotaxis, Phyllophaga, Polyphylla, Hoplia, Anomala, Pelidnota, Cyclocephala, Euetheola, Ligyrus, Coelosis, Enema, Strategus, Xyloryctes, Spodistes, Archophileurus, Hemiphileurus and Phileurus are included. Higher specific diversity is presented in the genera Phyllophaga (16 spp.) and, Anomala (11 spp.). Phyllophaga tenuipilis (Bates), P. ravida (Blanchard), Xyloryctes lobicollis Bates and, Anomala inconstans Burmeister were the most abundant species in the samples. Archophileurus simplex (Bates) and Phyllophaga anolaminata (Moser) are cited for first time in México, and Anomala decolor Bates, A. forreri (Bates), Diplotaxis consentanea Bates, D. simillima Moser and, Hoplia squamifera Burmeister are recorded for first time from Chiapas state. A key to the 50 species is included. Most genera represented in the study area have Neotropical origin, but 51 % of the species belong to Paleoamerican dispersal pattern (sensu Halffter 1976). The Melolonthidae fauna of Villa Las Rosas area is 27.72% similar (QS Sorensen) with the species found in Los Tuxtlas, Veracruz; and 27.40% similar with the species from the mountains at northeast of Hidalgo, Mexico.
