Triozidae Löw, 1879 Bactericera Puton, 1876

Comments. Bactericera is a predominantly Holarctic genus with over 160 described species (Ouvrard 2020). Its known host range is unusually wide, covering 13 families and 11 orders of eudicots and one family and one order of monocots (Burckhardt and Lauterer 1997b). Salicaceae hosts the largest number of Bactericera species (over 40 spp.), followed by Compositae (17 spp.) and Solanaceae (6 spp.) (Burckhardt and Lauterer 1997b). Not included in these counts are five polyphagous Bactericera species.

Bactericera is a taxonomically difficult genus. Particularly problematic in this respect are the Nearctic species associated with Salix. When trying to identify and name the species on Salix caroliniana Michx. from Florida it became evident that this group is in a taxonomic chaos. For putting our conclusions regarding the Florida species in a general context we provide a list of all valid Nearctic Bactericera species associated with Salix with synonyms and homonyms (Appendix 1).
