Abstract

This work provides general descriptions, illustrations, molecular diagnostic data, taxonomic keys, slide mounting recommendations, and Florida distribution records for Fiorinia Targioni Tozzetti species occurring in the USA. Species treated are F. externa Ferris, F. fioriniae (Targioni Tozzetti), F. japonica Kuwana, F. pinicola Maskell, F. phantasma Cockerell & Robinson, F. proboscidaria Green, and F. theae Green. New descriptions of second-instar males and females of all seven species in addition to first-instar nymphs and adult females of F. phantasma and F. proboscidaria are presented. Taxonomic keys to second-instar males and females are developed for the first time and previously available taxonomic keys to first-instar nymphs and adult females are improved. DNA sequences were used to further evaluate the monophyly of Fiorinia and provide additional diagnostic tools for Fiorinia species. Multigene phylogenetic analyses, COI barcoding methods, and examination of type material indicate that F. yongxingensis Liu, Cai & Feng, 2020, syn. nov. is a junior synonym of F. phantasma. A morphological survey of the genus demonstrates, for the first time, the utility of second-instar males for diagnostics. This study will help inform regulatory and pest management decisions by facilitating morphological and molecular identification of adventive Fiorinia species occurring in the USA.
