First fossil record of Cedusini in the Eocene Baltic amber with notes on the tribe (Hemiptera: Fulgoromorpha: Derbidae)

摘要

New extinct genus and species—Emeljanovedusa gentarna gen.n. et sp.n., of the planthopper family Derbidae, tribe Cedusini, from the middle Eocene Baltic amber is described. New extant genera of Cedusini are established: Hauptenia gen.n., Muiredusa gen.n., Prodma gen.n. New combinations are given: Hauptenia magnified (Yang & Wu, 1993), comb.n.; H.jacula (Yang & Wu, 1993), comb.n.; H.fellea (Yang & Wu, 1993), comb.n., H. glutinosa (Yang & Wu, 1993), comb.n., H. idonea (Yang & Wu, 1993), comb.n., Muiredusa brunnea (Muir, 1914), comb.n., M. littorea (Yeh & Yang, 1993), comb.n., M. ignota (Yeh & Wu, 1993), comb.n., Produsa concava (Yang & Wu, 1993), comb.n., and P. cubica (Yang & Wu, 1993), comb.n. Key to generaplaced in Cedusini is given and placementof the fossil genus and its relationships within the tribe are discussed.
