Resumen:
Planidia are free-living, mobile first-instar larvae that are notable in their abilityto transition across different larval stages of their host, and for completing theirdevelopment on the host prepupa as ectoparasitoids, effectively acting as larvalpupalexternal koinobionts. Chalcidoid taxa with a planidium form a monophyleticgroup, the planidial larva clade (PLC). We conducted a phylogenomic study of the PLCusing anchored hybrid enrichment data. Phylogenetic analyses support the backbonerelationship of PLC as: (Eutrichosomatinae, ((Philomidinae, Chrysolampinae),(Perilampinae, Eucharitidae))). Although excluded from the main analyses, the genusJambiya, based on only 11 loci recovered, was placed as the sister of Chrysolampinae+ Philomidinae or Perilampinae + Eucharitidae. Our results demonstrate that Perilampidae(Philomidinae, Chrysolampinae and Perilampinae) are paraphyletic. Divergencedating based on four node calibrations based on fossils suggests that the PLCarose approximately 111 Ma and the evolution of ant parasitism at least 64 Ma. Hostassociations, direct versus indirect hyperparasitism, ability to attack a host within acocoon, soft versus hard planidial forms and mobility of the planidium were exploredusing a likelihood-based ancestral state reconstruction method. A revised higherlevelclassification of the PLC is proposed, with Eutrichosomatinae elevated toEutrichosomatidae (stat. rev.), Chrysolampinae and Philomidinae placed inChrysolampidae (stat. rev.), Perilampidae (stat. rev.) restricted to what was referredto as Perilampinae, and Eucharitidae maintained with four subfamilies, withAkapalinae (unknown biology) as sister group to the core Eucharitidae, all of whichare ant parasitoids. Jambiya is treated as an incertae sedis taxon within the planidialclade.
