TLDR
It is argued for conserving the family-group names Chlorocyphidae, Euphaeidae and Dicteriadidae, as well as retaining Epiophlebiidae in the suborder Anisozygoptera, while the proposal to separate Chlorogomph Families, Cordulegastridae and Neopetaliidae from Libelluloidea in their own superfamily CordUlegastroidea is adopted.

A phylogenetic analysis of the extant Aeshnidae (Odonata: Anisoptera)

TLDR
A cladistic analysis of the world Aeshnidae is presented, based on fifty-eight characters of adult and larval anatomy, and the strict consensus tree obtained after successive weighting shows that the subgroups defined traditionally for AeshNidae are paraphyletic or polyphyletic.

A revision of Metaleptobasis Calvert (Odonata: Coenagrionidae) with seven synonymies and the description of eighteen new species from South America.

TLDR
Examination of over 1,400 specimens of the neotropical genus Metaleptobasis Calvert, 1907, allowed me to unequivocally associate older names with species, distinguish between specific and intraspecific variability, associate both sexes for each species, and recognize the existence of female polymorphism.
