A species key and checklist for all described Ancistrocerus that occur south of the Rio Grande are provided. New synonymy includes Odynerus bolivianus Brèthes = Ancistrocerus pilosus (de Saussure), while the subspecies bustamente discopictus Bequaert, lineativentris kamloopsensis Bequaert, lineativentris sinopis Bohart, tuberculocephalussutterianus (de Saussure), and pilosus ecuadorianus Bertoni, are all sunk under their respective nominotypical taxa.

Many researchers also consider casteless nest-sharing an antecedent to eusociality. Together, these ideas endorse a stepwise progression of social evolution in wasps (solitary → casteless nest-sharing → eusociality with rudimentary behavioral castes → eusociality with preimaginal caste-biasing → morphologically differentiated castes). Here we infer the phylogeny of Vespidae using sequence data generated via anchored hybrid enrichment from 378 loci across 136 vespid species and perform ancestral state reconstructions to test whether rudimentary and monomorphic castes characterized the initial stages of eusocial evolution. Our results reject the single origin of eusociality hypothesis, contest the supposition that eusociality emerged ...

Phylogenies provide insight into the ancestral states and environmental contexts that subserve worker/queen decoupling, and thus are the framework for understanding origins of eusociality. We present a thorough phylogenetic analysis of the Vespidae, utilizing phenotypic and molecular data of previous studies in conjunction with newly acquired data, in an effort to explain how solitary ancestors may have crossed the threshold of eusociality. Previous studies show conflicting phylogenies for Vespidae, and differ in their conclusions regarding whether eusociality has evolved once or twice in these wasps. The causes of phylogenetic incongruence are numerous and so we postulate the primary drivers of phylogenetic incongruence complicating reconstruction of the Vespidae phylogeny. Simultaneous analysi...

Parasitoid wasps of this superfamily are beneficial insects that attack and kill other arthropods and are important for understanding diversification and the evolution of life history strategies related to parasitoidism. Further, some lineages of parasitoids within Ichneumonoidea have acquired endogenous virus elements (EVEs) that are permanently a part of the wasp’s genome and benefit the wasp through host immune disruption and behavioral control. Unfortunately, understanding the evolution of viral acquisition, parasitism strategies, diversification, and host immune disruption mechanisms, is deeply limited by the lack of a robust phylogenetic framework for Ichneumonoidea. Here we design probes targeting 541 genes across 91 taxa to test phylogenetic relationships, the evolution of parasitoid strategies, and the utility of probes to capture po...
