They are monophagous on the Loranthaceae Struthanthus uraguensis (Trioza struthanthi sp. n.), Tripodanthus acutifolius (Trioza tripodanthi sp. n.) and narrowly oligophagous on Tristerix spp. (Trioza tristericis sp. n.). For a fourth species (Trioza vagata sp. n.) host information is unavailable but its association with mistletoes is likely. The four species form a putative monophyletic group, together with three North American species (Trioza acuminata Tuthill, T. incidata Tuthill and T. phorodendrae Tuthill), based on the apically incised paramere, the highly modified valvulae of the female ovipositor and the host association with mistletoes. T. acuminata stat. n. from California is raised to species rank (originally described as subspecies of T. phorodendrae). The Trioza struthanthi-group is diagnosed and a key for the identification of its constituent members is provided. New host data are provided for Calophya sp. from Brazil as well as for Notophorina fusca Burckhardt and Zonopelma australis Burckhardt from Chile. Host plant and biogeographical patterns of mistletoe feeding psyllids around the world are briefly discussed.  aBiogeography  aHerbivores  aSternorrhyncha  aTaxonomy  aTriozidae  aTaxonomia  aHemiparasitic plants  aPhytophagy  aSystematics1 aDÍAZ, F.1 aQUEIROZ, D.
