Acrydium bispinosum Dalman, 1818: 77 [description] (holotype — ♀, type locality: unknown, in NHRS.)

Criotettix bispinosus ( Dalman, 1818) : Bolívar, 1887: 226.

Formosatettix hainanensis Zheng, 2012: 15 [description] (holotype — ♀, China: Hainan prov., Lingshui County, in IZSNU, examined); Deng, 2016: 279; Wei, Deng & Lu, 2019: 1006; syn. nov.

Type material examined. Holotype Formosatettix hainanensis , ♀, larva, China: Hainan prov., Lingshui County, 15 August 1983, in IZSNU.

Notes. We examined the type specimen of Formosatettix hainanensis and found that it has hind wings. Therefore, it does not belong to Formosatettix . The hind wings of the type specimen have only radial venation, without crossveins ( Fig. 3B ), indicating that it is a nymph. Unfortunately, the hind legs of the type specimen are missing. In the original description of Formosatettix hainanensis, Zheng (2012) provided a drawing showing that the antegenicular teeth of the dorsal margin before the knee of the hind femora were absent ( Fig. 3D ), indicating that the specimen is a nymph.

Formosatettix hainanensis ( Zheng, 2012) syn. n. represents a nymph of Criotettix bispinosus , which has a widened vertex, elongated lateral carinae of prozona, and a slightly elevated median carina of the pronotum before shoulders.
