Phylogenetic relationships of the Neotropical damselflies Polythoridae
I'm currently reconstructing the evolutionary relationships within the Neotropical family Polythoridae. It comprises 7 genera: Cora, Miocora, Euthore, Polythore, Chalcothore, Chalcopteryx and Stenocora.
Species delimitation and diversification of the highly polymorphic Polythore damselflies
The Neotropical damselflies from the genus Polythore are stunningly colourful; their wings display orange, black and/or white . Despite this color diversity, they lack variation in classical reproductive traits (e.g. male genitalia) commonly used for species description.The genus comprises 21 described morphospecies distributed along the Eastern slopes of the Andes cordillera and the Amazon basin, through Colombia to Northern Bolivia. They dwell in small fast flowing creeks with highly oxygenated waters; their larvae are the only mesoamerican damselflies that possess abdominal gills and highly modified structures at their posterior end for stability in fast flowing waterfalls. Are these morphospecies independent lineages? Why are they so colorful?
