Zethus is the largest genus in Vespidae with over 270 species. It currently divided into four subgenera: Z. (Zethus), (Zethoides), (Zethusculus) and (Madecazethus). While last three are restricted to certain biogeographic areas, first spread through western eastern hemispheres. Studies have shown possible phylogenetic incongruence regarding this current division even raised possibility of parap...
