A Parasitoid Puzzle: Phylogenomics, Total-evidence Dating, and the Role of Gondwanan Vicariance in the Diversification of Labeninae (Hymenoptera, Ichneumonidae)
Abstract Biogeographic patterns in the Southern Hemisphere have largely been attributed to vicariant processes, but recent studies have challenged some of the classic examples of this paradigm. The parasitoid wasp subfamily Labeninae has been hypothesized to have a Gondwanan origin, but the lack of...

Abstract Biogeographic patterns in the Southern Hemisphere have largely been attributed to vicariant processes, but recent studies have challenged some of the classic examples of this paradigm. The parasitoid wasp subfamily Labeninae has been hypothesized to have a Gondwanan origin, but the lack of divergence dating analysis and the discovery of a putative labenine fossil in Europe pose a challenge to that idea. Here we used a combination of phylogenomics, divergence dating and event-based biogeographical inference to test whether Gondwanan vicariance may explain the distribution patterns of Labeninae. Data from genomic ultraconserved elements were used to infer the phylogeny of Labeninae with 54 species from 9 genera and a broad selection of 99 outgroup taxa. Total-evidence divergence dating places the origin of Labeninae at around 146 mya, which is consistent with a Gondwanan origin but predates the full separation of Africa and South America.
