Emesinae sensu lato (Hemiptera: Reduviidae: Emesinae, Saicinae, and Visayanocorinae) are the only hemipterans known to prey on spiders in their web and do so using complex predation strategies. Potentially due to this unexplored niche, Emesinae are species rich, with over 950 species in 95 genera. Emesinae additionally differ from other Reduviidae in having several cosmopolitan genera spread across three tribes as well as a number of endemic island species. Though several authors suggested that these genera are not cosmopolitan and are in need of revision, preliminary results support their monophyly, as well as suggest a relatively young age for the subfamily. This suggests that dispersal, rather than vicariance, led to their wide range. Using a combined analysis of Sanger sequencing (175 ingroup taxa) and Anchored Hybrid Enrichment data (12 taxa), I generated a phylogenetic hypothesis and determined relationships between subfamilies, tribes and genera.
