A systematic survey was conducted to assess the diversity of Buprestidae in the tropical deciduous forest at El Limón de Cuauchichinola, municipality of Tepalcingo, Morelos State, Mexico. Samples were collected five days each month for one year, and the UAEM (CIUM) insect collection was examined for Buprestidae specimens. Four subfamilies, 12 tribes, 19 genera and 73 species were recorded, with the genera Agrilus Curtis, 1825, Chrysobothris Eschscholtz, 1829, and Acmaeodera Eschscholtz, 1829 having the greatest number of species. Nonparametric estimator analysis estimates that only 68% of buprestid species occurring in the forest were recorded. The annual value of diversity calculated with the Shannon-Wiener index was 3.08. Maximum diversity and evenness values were recorded during the rainy season. Maximum richness and abundance values were recorded during July and August, the months with the highest amount of rainfall, and correlated with rainfall 78% and 72%, respectively.
