TL;DR: Evidence from biogeography, the fossil record, and phylogeny indicates that this group, possible sister group of remaining Corduliidae s.s., was probably already present in the Early Cretaceous.
Abstract: The holotype of Libellulosoma minuta , until now regarded as the unique specimen of this monotypic genus and considered lost for half a century, was found again in the dragonfly collection of the Museum National d’Histoire Naturelle in Paris. A second specimen, also from Madagascar (probably East Madagascar) was found in the collection Rene Martin together with the holotype. A redescription, including the structure of the secondary copulatory apparatus, is provided. The genus Libellulosoma is closely related to the genera Pentathemis and Aeschnosoma , and its membership in the clade Aeschnosomata is well supported. Evidence from biogeography, the fossil record, and phylogeny indicates that this group, possible sister group of remaining Corduliidae s.s., was probably already present in the Early Cretaceous.
TL;DR: The genus Aeschnosoma appears closely related to the Australian genus Pentathemis Karsch 1890, and also to the Madagascan genus Libellulosoma Martin 1907, and some putative plesiomorphies would place this clade sister group of the remaining Corduliidae s.str.
Abstract: Three new species of the genus Aeschnosoma are briefly described and illustrated. A. pseudoforcipula n. sp. and A. heliophila n. sp., both from the Brazilian Central Plateau are respectively related to the two Amazonian species A. forcipula Hagen in Selys 1871, and A. auripennis Geijskes 1970. A. louissiriusi n. sp. from Northern Brazil is not closely related to any known species. Based on larval and adult derived characters, the genus Aeschnosoma appears closely related to the Australian genus Pentathemis Karsch 1890, and also to the Madagascan genus Libellulosoma Martin 1907. The clade Aeschnosomata nov. is erected to receive the three genera. Some putative plesiomorphies would place this clade sister group of the remaining Corduliidae s.str.
