Resumen:
A study on the patterns of richness, diversity and abundance of the
Odonata from Santiago Dominguillo, Oaxaca is presented here. A total of
1601 specimens from six families, 26 genera and 50 species were obtained
through monthly samplings of five days each. Libellulidae was the most
diverse family (21 species), followed by Coenagrionidae (19), Gomphidae
(4) and Calopterygidae (3). The Lestidae, Platystictidae and Aeshnidae
families were the less diverse, with only one species each. Argia was
the most speciose genus with 11 species, followed by Enallagma,
Hetaerina, Erythrodiplax and Macrothemis with three species each and
Phyllogomphoides, Brechmorhoga, Dythemis, Erythemis and Orthemis with
two species each. The remaining 17 genera had one species each. Argia
pipila Calvert, 1907 and Leptobasis vacillans Hagen in Selys, 1877 were
recorded for the first time for the state of Oaxaca. We also analysed
the temporal patterns of taxonomic and phylogenetic divergence for the
Santiago Dominguillo Odonata assemblage: the Shannon diversity value
throughout the year was 21.07 effective species, while the Simpson
diversity was 13.17. In general, the monthly phylogenetic divergence was
higher than expected for taxonomic distinctness, and lesser for average
taxonomic distinctness. Monthly diversity, evenness and taxonomic
divergence showed significant positive correlations (from moderate to
strong) with monthly precipitation values. The analysis of our results,
however, indicates that an increase in rainfall not only influences the
temporal diversity of species, but also the identity of supraspecific
taxa that constitute those temporal assemblages, i.e. there is an
increase in temporal phylogenetic divergence.
