Taxonomy and host plant relationships of the Trioza apicalis Förster complex (Hemiptera, Homoptera: Triozidae)

Abstract

AbstractThe complex of 8 species centred around the carrot psyllid, Trioza apicalis, is defined and keys are given to the species. The species are: T. apicalis Förster, T. stygma Tuthill, T. laserpitii Burckhardt & Lauterer, T. carpathica Dobreanu & Manolache, T. mica Loginova, T. mesembrina sp. n., T. lautereriella sp. n. and T. anthrisci nom. n. (for T. pallida Haupt, nom. praeocc.). The subgenus Dyspersa Klimaszewski is synonymized with Trioza Förster. The species are oligophagous on umbellifers of the subfamily Apioidea and, except for T. anthrisci, produce deformations on the host.
