Sinochresmoda, Zhang, Xin-Wen, Ren, Dong, Pang, Hong & Shih, Chung-Kun, 2008

Zhang, Xin-Wen, Ren, Dong, Pang, Hong & Shih, Chung-Kun, 2008, A new genus and species of Chresmodidae (Insecta: Gryllones) from Upper Jurassic-Lower Cretaceous of Yixian Formation, Inner Mongolia, China, Zootaxa 1702, pp. 26-40 : 27

Genus Sinochresmoda gen. nov. Zhang, Ren, and Pang

Type species. Sinochresmoda magnicornia sp. nov. Zhang, Ren, and Pang

Etymology. The generic name is a combination of the Greek prefix sino- ( China) and Chresmoda (the type genus of this family). Gender: feminine.

Diagnosis. Head small. Both male and female have wings. Antennae exhibit sexual dimorphism. Scape expanded slightly in female, while expanded significantly in male. The first segment of the flagellum is elongated in both genders, but incurvated as a pair of brackets in male, while normally straight in female. Legs are long and narrow with similar shape; mid leg femora are the longest. Coxae on the same side of thorax are far apart from each other. Fringe hairs along the wing margins, a unique feature for Chresmodidae , are dense, wavy and bundled together.

Comparison. Sinochresmoda n. gen. is closely related to Chresmoda Germar, 1839 , but can be distinguished by the following characters: expansion of the first segment of antennae and male with wings. Fringe hairs along the wing margins are absent in Chresmoda . Saurophthiroides Ponomarenko, 1986, is represented only by one specimen (probably nymph) without wings. The new genus differs from it by larger body size and expansion of the first segment of antennae.
