Abstract

Taxonomic and systematic research with Chrysididae has been largely neglected in recent decades, particularly with respect to the Neotropical fauna. In Brazil, the only comprehensive studies of Chrysididae were done by the naturalist Adolfo Ducke in the early 20th Century. The main goal of this research project was to conduct a phylogenetic study of Ipsiura (Chrysidini) integrated with a revision of the taxonomic limits of the genus and its species. In the end, it was possible to recognize 34 species from the material studied. New records of occurrence of the genus in Brazil were documented and a list with all currently valid names, geographical distributions and repositories are presented. Furthermore, this study resulted in the construction of a pictorial key to recognize all species with occurrence in Brazil, proposed new diagnosis to distinguish the species, and offered geographical distribution maps. In the phylogenetic analysis 66 morphological characters were constructed, and coded for 33 species of Ipsiura and 20 outgroup terminal species. Ipsiura was recovered as monophyletic in all phylogenetic results, positioned as sister-group of the clade composed by Exochrysis + Neochrysis. Part of internal relationships in the genus, despite specific uncertainties, could be better understood by cladistic approach. Species-groups within Ipsiura were evidenced to be congruent with the proposed characters. The phylogenetic relationships among Ipsiura and the major lineages of Neotropical Chrysidini could be better understood and formally discussed, and the obtained results in the present study provide the basis for morphology understanding in the future research to be done in more wider analysis involving different groups in Chrysidini (AU)
