Short summary
Baltocar sontagae sp. nov. and Pseudomesauletes lobanovi sp. nov. from the family Rhynchitidae are described from Eocene Baltic amber. It is the first record of Pseudomesauletes from Baltic amber. Keys to species of the genus Baltocar and to the Eocene species of the genus Pseudomesauletes are given. Assumed trophic relationships of the genus Baltocar with Cupressaceae and Pseudomesauletes lobanovi sp. nov. with Rosaceae are discussed.
