Two new fossil Tetrigidae (Insecta: Orthoptera: Caelifera) from the Grube Messel (Germany)
摘要
The Grube Messel is an important Fossillagerstätte in Germany and has a high importance because of the excellently preserved specimens, especially in terms of insects. So far no Orthoptera from the Eocene of Grube Messel have been described. To change this, here we describe two new genera and species of Tetrigidae: Messeltettix cryptoantennatus gen. et sp. nov. and Archaeoarmatus messelensis gen. et sp. nov. We make suggestions on the systematic position of these species and discuss their meaning for our understanding of the evolution of this interesting family of grasshoppers.
