Genus Gymnogryllus Saussure, 1877

Gymnogryllus Brunner von Wattenwyl 1893: 197; Gorochov 1983: 321; Yin and Liu 1995: 194; Ma and Zhang 2011: 31; Gorochov 2022: 4.

Brachytrypus (Gymnogryllus) Saussure, 1877: 291.

Type species.

Gryllus elegans (= Gymnogryllus leucostictus ). Brachytrypus (Gymnogryllus) Saussure, 1877: 291.

Distribution.

India, Australia, western Himalayas, Burma, Vietnam, Malaysia, China.

Diagnosis.

Body large. Head, pronotum and much of hind femur blackish brown; rest of body of light color. Light brown bands uniformly distributed over posterior peduncle. Forewings not reaching tip of abdomen; hind wings largely surpassing abdomen. Mirror inclined rectangular. The length of the apical field of forewings varies among individuals. Subgenital plate shaped as hook. Genitalia large, in caudal view, epiphallus arch-shaped and the apically armed with a pair of long teeth. The space between the teeth and the shape of them varied among individuals (Fig. 5 View Figure 5 ). Ovipositor very short, almost straight.

Remarks.

Eight species of Gymnogryllus are reported from China, and six of them have been found in Yunnan. Among them, G. longus , G. tumidulus , G. yunnanensis , and G. striatus have been described for differences in the angle of the epiphallic apex and the length of the apical field of tegmen. However, they are similar to G. odonopetalus in appearance and can be collected from the same location at the same time. We compared specimens collected from the same site and concluded that these two features present intraspecific variation and are unreliable for species delimitation. We consider that all four taxa are synonyms of G. odonopetalus .
