Abstract
AbstractTheNeotropics are a hotspot of global diversity for many groups of organisms, including the dragonflies and damselflies (Insecta:Odonata). While the number of biodiversity surveys and new species descriptions forNeotropical odonates is increasing, diversity in this region is still under‐explored, and very few studies have looked at the genetic and morphological diversity among (and within) species. Here, we present an overview of the evolutionary history of theNeotropical damselfly familyPolythoridae. The family comprises 57 species across seven genera:ChalcopteryxSelys,ChalcothoreDeMarmels,CoraSelys,EuthoreSelys,MiocoraCalvert,PolythoreCalvert andStenocoraKennedy. Using a multi‐locus approach, mitochondrial (COI,ND1, 16S) and nuclear (18S, 28S,EF1‐alpha) genes were concatenated to estimate phylogenetic relationships. Our results support five monophyletic clades, which were not always congruent with the genera previously considered to be monophyletic. OnlyPolythorewas recovered as monophyletic, and within it there was geographical structure. We propose the following new genus‐level classification:Chalcothore,Chalcopteryx,Coras.s.,Coras.l.,Miocora,Euthores.l andPolythore.In addition, we proposed the following new combinations:Miocora aureacomb.n.,Miocora chirripacomb.n.,Euthore confusacomb.n.,Euthore kleneicomb.n., andEuthore terminaliscomb.n.,based on our phylogenetic analyses, our evaluation of morphological characters and their geographical distribution: these data each support the monophyletic entities we recover here.This published work has been registered in ZooBank,http://zoobank.org/urn:lsid:zoobank.org:pub:E9E10CD8‐6A04‐4F2E‐A632‐1B998BAFB193.
