Abstract:

A total of 587 adult Odonata belonging to six families, 25 genera, and 52 species were collected in 2005 from the tropical dry forests of Huatulco, Oaxaca, Mexico by bimonthly samplings of five days each for one year. Libellulidae with 26 species was the richest family, followed by Coenagrionidae (18), Calopterygidae (3), Aeshnidae and Gomphidae (2), and Lestidae (1). Argia with nine species was the most speciose genus, followed by Erythrodiplax (4), Dythemis, Erythemis, Hetaerina, Micrathyria, and Macrothemis (3). The remainder of the genera were represented by only two or one species. The observed species richness represented approximately 85.9 % of the estimated species richness for Huatulco. Maximum values of species richness, abundance, and diversity apparently coincide with the months of greatest rainfall. No relationship between phylogenetic diversity with temperature and precipitation was found.
