A new species of Aboilus (Insecta, Orthoptera, Prophalangopsidae) from the Middle Jurassic of Daohugou, Inner Mongolia, China

摘要

A new species, Aboilus chinensis sp. nov., is described and attributed to Aboilus (Insecta, Orthoptera, Prophalangopsidae, Aboilinae), from the Middle Jurassic of Daohugou in Inner Mongolia, China. The tegminal diagnostic characters for Aboilus Martynov, 1925 are revised. The fossil record of Aboilus from China is reviewed. The Mesozoic genus Aboilus Martynov, 1925 was originally placed in the family Aboilidae (Martynov 1925), and later transferred to Prophalangopsidae by Zeuner (1939). Although being a diverse group of Prophalangopsidae (Orthoptera), the genus is rarely represented by male tegmina. It occurs in Middle-Late Mesozoic deposits throughout Europe and East-Middle Asia (Martynov 1925; Zeuner 1939; Sharov 1962, 1968; Lin 1965, 2006; Fujiyama 1978; Hong 1982, 1983; Gorochov 1995, 2003; Gorochov et al. 2006). Very recently, we collected some Prophalangopsidae from the Middle Jurassic of Daohugou, China. Herein, we report a new species assigned to Aboilus, and review the record of Aboilus from China.
