Description
Summary:Two adult females of Elcanidae (Orthoptera: Elcanoidea) from the Lower Cretaceous Yixian Formation of China are described as a new species, Probaisselcana euryptera sp. nov. The new materials have both wings and body structures well preserved. The new species differs from all other Elcaninae species in forewing venation and body features. The new specimens provide more morphological information of body structures of elcanids. The function of their flattened metatibial spurs is discussed.
