A New Species of the Family Juraperlidae (Insecta: Grylloblattida) from the Middle Jurassic of China

摘要

Juraperla grandis sp. nov. (Grylloblattida: Juraperlidae) is described from the Daohugou locality (Middle Jurassic, China). Its wing venation is very similar to that of Juraperla daohugouensis Huang and Nel, 2007 (Grylloblattida: Juraperlidae), in the particular occurrence of a supplementary longitudinal vein in the area between the anterior wing margin and ScP. The larger size of the new specimen, the lower number of CuA1 branches, and the occurrence of two rows of cells between MP and CuA in forewings justify the erection of a new species, J. grandis sp. nov.. The material also preserved hind wing and body structures, described for the first time in Juraperlidae.
