Discovery of Two New Peculiar Subgenera and Two New Species of Tipula Linnaeus, 1758 (diptera, Tipulidae) from Baltic Amber

Two new fossil subgenera and two new fossil species of the genus Tipula Linnaeus, 1758, Tipula（Succinica） berendti subgen. and sp. n. and Tipula（Gedanica） adamowiczi subgen. and sp. n., are described from Baltic amber and compared with other species of Tipula known from the Eocene. The two new subgenera and species described herein are an excellent bridge between recent specimens and those preserved in sedimentary rocks, and thus enrich knowledge on the evolution of the family.
