A New Species of Eocene Whitefly—Gregorites michalskii sp. nov. (Hemiptera, Sternorrhyncha, Aleyrodidae) from Baltic Amber

This paper describes a new species of extinct whitefly in the genus Gregorites Drohojowska & Szwedo, 2024, from the family Aleyrodidae. This species has been identified based on an inclusion in Eocene Baltic amber. This represents the eighth documented species of the genus and contributes new data to our knowledge of the disparity and taxonomic diversity of whiteflies in Eocene Baltic amber. The discovery of a further Gregorites species, previously known only from succinite on the western coast of Jutland, raises questions about the amberiferous deposits, their geology and history, and on palaeodistributions of the whiteflies. These are briefly reviewed and discussed.
