Thelaxes suberi (Del Guercio) was found for the first time in North America. The first collection was on a single potted oak tree in rural Marion County, Florida. Morphological and molecular techniques were used to determine the identity of this adventive species. The find was reported first only as a quarantinable pest, because the prior whereabouts of the potted plant were not known. However, suction trap collections in Polk County in 2020 indicated that the species is established in Florida. It is not known if this species will become numerous on oaks in North America.
