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.

来自墨西哥瓦哈卡州圣地亚哥·多明古里奥地区热带干旱森林的卵形动物组合的丰富度，多样性和丰富度的模式（昆虫纲：大齿蝠ata）

本文介绍了对来自瓦哈卡州圣地亚哥·多明古里奥（Santiago Dominguillo）的蜻蜓目（Odonata）的丰富度，多样性和丰度的模式的研究。通过每月采样五天，共获得了来自六个科，26属和50种的1601个标本。Libellulidae是种类最多的科（21种），其次是Coenagrionidae（19），Gomphidae（4）和Calopterygidae（3）。Lestidae，Platetytictidae和Aeshnidae科的多样性较少，每个科只有一种。Argia是最特殊的属，有11种，其次是Enallagma，Hetaerina，Erythrodiplax和Macrothemis，各有3种，而Phyllogomphoides，Brechmorhoga，Dythemis，Erythemis和Orthemis各有两种。其余的17属各有一个物种。Argia pipila Calvert，1907年； Leptobasis vacillans Hagen，在Selys，瓦哈卡州首次记录了1877年。我们还分析了Santiago Dominguillo Odonata组合的分类学和系统发育差异的时间模式：全年的Shannon多样性值为21.07有效种，而Simpson多样性为13.17。通常，每月的系统发育差异高于分类学差异的预期值，而平均分类学差异则较小。月度多样性，均匀度和分类学差异与月降水量值呈显着正相关（从中度到强度）。然而，对我们的结果的分析表明，降雨的增加不仅影响物种的时间多样性，而且还会影响构成这些时间组合的超特异类群的身份，即
