  • 摘要:New data on the genus Elephantomyia (Diptera: Limoniidae) from Baltic amber are presented. A new subgenus Hoffeinsonia subgen. nov. is established with one new species: Elephantomyia ( Hoffeinsonia) prima sp. nov. The new subgenus is characterized by a wing at most 2.5 × as long as it is wide without a darker pattern along the veins Sc and R 1, elongate Sc, straight vein R 1, sharp half of vein R 2+3+4 sharply arched to the upper edge of the wing, short, wide, trapezoidal d-cell and oval pterostigma. The fossil subgenus Hoffeinsonia subgen. nov. shares features with the extant subgenera Elephantomyodes and Elephantomyia. One other extinct species of Elephantomyia was discovered and described herein as E. (s. str.) christelae sp. nov. Such features as a very elongate vein R 2+3+4, 2.5 × as long as the Rs easily allowing this new species to be distinguished from the other fossil representatives of the genus Elephantomyia. The taxonomic decision on Elephantomyia grata as a species placed in nominative subgenus is provided. A list and key of fossil species of Elephantomyia are given. The morphological pattern of the genus is discussed in relation to the adaptation to a specific food spectrum, coevolution with Angiospermae of the representative genus Helius known since Cretaceous and closely related to this genus representatives of the much younger genus Elephantomyia.
