* Trioza adventicia Tuthill, 1952

Materials examined. Interceptions from USA: California ( FSCA, dry and slide mounted, ethanol).

Diagnosis. Description by Taylor and Martoni (2020). Separated from other Florida psyllids as indicated in the generic key above. This species makes pit galls on the undersides of Syzygium ( Mead 1994b, as “ T. eugeniae Froggatt ”), commonly known as “eugenia” in California.

Distribution. Australia, adventive in New Zealand and USA (CA, FL) ( Taylor and Martoni 2020).

Host plants. Syzygium P. Browne ex Gaertn. spp. ( Myrtaceae ).

Comments. Trioza adventicia Tuthill, 1952 , described from New Zealand, is the correct name for Trioza eugeniae auct. nec Froggatt, 1901 ( Taylor and Martoni 2020). This species does not occur in Florida, but it is intercepted in Florida on Syzygium paniculatum Gaertn. (especially on topiaries) ( Mead 1994b). Taylor and Martoni (2020) had specimens from California and Florida. They state clearly that the populations in Florida have been eradicated, and FSCA numbers given in the paper match those in our records of intercepted populations. We have 15 recorded interceptions of this species since 1985.
