The IEXA Entomological Collection at Instituto de Ecología, A. C. (Xalapa, Veracruz, Mexico) is one of the most important scientific collections in Mexico based on its taxonomic and geographic coverage and number of specimens (approx. 400,000), including its name-bearing types. The insect orders best represented in the collection are Coleoptera, Di...

Basal metabolic rates (BMRs) increase with temperature and body mass. Environmental temperatures rapidly change in tropical mountains due to elevation (macro scale) and vegetation structure (micro scale). Thus, tropical mountains are good settings for testing the effects of temperature on BMRs. We measured the BMRs at four temperature ranges on six...

In this study, we present the first attempt at a molecular phylogenetic analysis of the entire family of Cordulegastridae involving 60% of its known species. Our analysis is in favor of reclassifica�tion of the members of the family into four genera: (i) the monophyletic genus Anotogaster Selys, 1854, with the number of known species reduced by thr...

The Libellulidae is the largest family of Odonata and is distributed around the world. Adult libellulids are distinguished from other anisopterans by the large eyes meeting dorsally at the top of the head; many of them have the wings strikingly patterned with bands and spots or are fully colored. Adults of most species are perchers, although those...

The Corduliidae (sensu stricto) comprises 22 genera and 164 species of mostly Holarctic genera, a few Neotropical groups, and a predominantly Australasian group related to Hemicordulia. Corduliids are strong fliers, mostly inhabiting areas around submontane torrential streams but also lakes, ponds, and bogs. Nymphs live usually in mucky edges of pr...

The Gomphidae is a large cosmopolitan family with high species richness comparable to that of Libellulidae. Gomphids exhibit several apparently ancestral characteristics, such as the widely separated compound eyes and unspecialized wing venation in the adults, 2-segmented fore- and middle tarsi in nymphs and adults, and 4-segmented antennae with an...

The Chlorogomphidae is a small family comprising three widely recognized genera: Chlorogomphus (47 species), Chloropetalia (4 species), and Watanabeopetalia (4 species). Chlorogomphids are large and spectacular dragonflies confined largely to the mountainous regions of tropical Asia. Nymphs can be found at stream edges, at pools, or at the bases of...

Odonata nymphs are distinguished from other aquatic insects by the presence of an enlarged, extendable, labium that is longer than the head. Nymphs of Zygoptera and Anisoptera suborders can be distinguished from each other because those of the former are slender, the head is wider than the thorax and abdomen, and the abdomen has three caudal gills....

The genera Idionyx Hagen, 1867, and Macromidia Martin, 1907, traditionally have been considered as belonging to the family Corduliidae, but recent phylogenetic studies based on morphological and molecular analyses consider them with uncertain position.
