AbstractThe species of the chrysidid genus Ipsiura are reviewed with emphasis on the taxa occurring in Brazil. In the present study 34 Ipsiura species are recognized, diagnosed, and illustrated. Two new species are described here: Ipsiura bohartiana Lucena sp. nov. and I. duckeana Lucena sp. nov., and two others are transferred from Neochrysis to Ipsiura: I. assecia (Linsenmaier, 1997), comb. nov. and I. guayanensis (Linsenmaier, 1997), comb. nov., increasing to 41 the total of valid species in the genus. New diagnoses and redescriptions are provided for 34 species based on study of their types. For the first time, a comparative and illustrated study of male genitalia is presented for the majority of Ipsiura species. Notes on types and depository collections, a revised key for identification of species along with illustrations of diagnostic features, as well as geographical distribution maps are also given.

Phylogenetic relationships and biogeography of the Ipsiura cuckoo wasps (Hymenoptera: Chrysididae)

“…Specimens of Ipsiura were listed in detail by Lucena et al . (). The characters presented in the matrix are considered applicable for both sexes, except when noted, because males and females of many Chrysidini are nearly identical morphologically (see List of characters in the Supplementary Material).…”

“…Illustrations of male genitalia for the majority of Ipsiura species are presented in Lucena et al . (). Female ovipositors were dissected and cleared following the same protocols.…”

“…The taxonomy of these genera was based on studies conducted independently and almost concomitantly by Bohart (), Kimsey () and Linsenmaier (). The taxonomic discrepancies resulting from those three contributions resulted in controversies about delimitation of some genera and the taxonomic placement of many species (details discussed by Kimsey & Bohart, ; Linsenmaier, ; Lucena et al ., ).…”

“…In the Neotropical region, the Chrysidini comprise 206 species distributed in nine genera (Kimsey, ,b). Four of these genera are particularly diverse and primarily Neotropical, with some taxa extending as far north as the southeastern U.S.A. (Kimsey & Bohart, ; Kimsey, ; Lucena et al ., ): Pleurochrysis Bohart, (36 spp. ), Neochrysis Linsenmaier, (19 spp.…”

“…Most Ipsiura species (see Lucena et al ., ) as well as species placed in closely related genera, such as the Exochrysis , Neochrysis and Pleurochrysis , are widely distributed in the Neotropical region, with many species occurring from Mexico to Argentina (Kimsey & Bohart, ). This distribution indicates that the Neotropics may have played an important role in the diversification of these cuckoo wasps, but this was never formally evaluated.…”
