The results of a study of the fauna of cerambycids of the tropical dry forest of San Buenaventura, Jalisco, México are presented. The study was carried out between November, 1996 and October, 1997. The collections were carried out during five days of every month and the collection methods included light trapping, Malaise trapping and direct collecting. A total of 109 species, 76 genera, 30 tribes and 5 subfamilies were recorded. The subfamily with the greatest number of species was Cerambycinae with 62, followed by Lamiinae with 40, Lepturinae and Prioninae with three and Disteniinae with one. The tribes with the largest number of genera and species were Trachyderini with 14 and 20, Acanthocinini with nine and 18 and Elaphidiini with eight and 15. The genera with the most species were Stenosphenus Haldeman with five and Eburia Lepeletier, Sphaenothecus Dupont, Lepturges Bates and Urgleptes Dillon with four. The richness value using the non-parametric estimator ICE was 151 species. The species abundance pattern showed few very abundant species and many with few individuals. The diversity value calculated with the Shannon Index over the entire year was 3.88. Species richness and abundance varied with time, with the highest values recorded in the rainy season and lowest values in the dry season. The fauna was more similar to the fauna of Chamela, Jalisco than to Sierra de Huautla, Morelos or El Aguacero, Chiapas and consists of 37% species endemic to México.
