“…The so called, T. eugeniae was first detected in California, USA in 1988, becoming a serious pest of ornamental lilly pilly, S. paniculatum (Downer et al ., 1991; Dahlsten et al ., 1995; Zuparko et al ., 2011). It was discovered in Florida in 1993 but was eradicated (Mead, 1994).…”

“…It was discovered in Florida in 1993 but was eradicated (Mead, 1994). A classical biological control program commenced with foreign exploration in Australia in 1991, resulted in the description of a new species of parasitoid, Tamarixia dahlsteni Zuparko (Zuparko et al ., 2011), and its importation into USA that has achieved subsequent partial biological control (Dahlsten et al ., 1995; Dreistadt et al ., 2004).…”

“…Sweet (Martoni et al ., 2016; Percy, 2017) but this is erroneous (see Discussion). T. eugeniae was first detected in California, USA in 1988, presumably accidentally introduced, and was widely dispersed on ornamental S. paniculatum in the plant nursery industry before becoming the subject of a biological control program (Dahlsten et al ., 1995).…”

The ‘Eugenia psyllid’ or ‘Lilly pilly psyllid’, widely recognized in Australia and in the USA as Trioza eugeniae Froggatt (Hemiptera: Triozidae), is not T. eugeniae, but rather T. adventicia Tuthill. In this study we assessed morphological comparisons of materials from throughout the native and introduced ranges and re-examined original descriptions of both taxa, together with Froggatt's type specimens of T. eugeniae. Furthermore, through DNA barcoding analyses, we confirmed the validity of both T. adventicia and T. eugeniae as separate species. We re-described both species to include additional characters not previously included and designated a lectotype for T. eugeniae. T. eugeniae has smaller fore wings that are slightly more elongate. These lack infuscation around veins R and R1, vein Rs is relatively longer, meeting the costa closer to the wing apex; with certain veins bearing long, fine divergent setae, a character not previously described. It has consistently three inner and one outer metatibial spurs. The male parameres appear narrowly pyriform with a weak dorsolateral lobe and weakly sclerotized apices. T. adventicia has larger fore wings that are slightly more ovate with dark infuscation around veins R and R1; vein Rs is relatively shorter, meeting the costa further from the wing apex, with veins lacking long, fine divergent setae. The usual configuration of two inner and one outer metatibial spurs, previously used to separate the two species, appears inconsistent. The male parameres appear a little more broadly pyriform with slightly more sclerotized apices. T. eugeniae refers to a distinct species which has a restricted distribution only in its native range in southern subcoastal New South Wales, Australia. T. adventicia refers to a separate species, with a natural distribution in eastern subcoastal Australia, but has been introduced widely in southern Australia, to New Zealand and the USA. This study elucidates a long history of misidentification of T. eugeniae in the nursery industry and in almost 30 years of literature on its biological control in the USA. Regardless, the biological control program, unknowingly, targeted the correct species of psyllid, T. adventicia, in its foreign exploration and importation of the appropriate parasitoid as a biocontrol agent in the USA. Despite being firmly entrenched in both the nursery trade and scientific literature, the name T. eugeniae is misapplied. While the acceptance of the valid name, T. adventicia, might be regarded as both problematic and protracted, this is the correct taxonomical attribution.

“…Psyllid damage can severely disfigure trees, which are commonly used in ornamental plantings. In cooler areas of the California coast, such as the city of San Francisco, the parasitoid populations do not increase quickly enough to respond to sudden increases in psyllid numbers (Dahlsten et al 1995(Dahlsten et al , 2000. This psyllid is sensitive to both frost and heat, and temperatures above 90˚F are known to inhibit population growth; common name: lillypilly psyllid, or eugenia psyllid.…”

A revised checklist to the species of Psylloidea (Hemiptera) from California is presented, with information on host plantdata, distributions, introduced and pest species, parasites, parasitoids, and predators, and biological control programs. Thelist includes 164 species, of which six are newly recorded. In total, this comprises a 26% increase in the number of speciesrecorded for California since the last published checklist in 1988. Choricymoza Bliven is a new synonym of PhylloplectaRiley, and 10 species previously in Euphalerus Schwarz are recombined under Nyctiphalerus Bliven. California has therichest native psyllid fauna in North America, and the influence of climatic and floristic diversity on this diversificationis considered. Key words: biogeography, host plant, jumping plant lice, species diversity, pest species.
