1. Bolivaritettix circocephalus Zheng, 1992 ( Figs. 2 , 24A )

Bolivaritettix circocephalus Zheng, 1992d: 83 [description] (holotype —♁, China: Tibet, Mêdog , in IZCAS).

Formosatettix torulosinota Zheng & Mao, 2002: 94 [description] (holotype — ♀, China: Yunnan prov., Weishan County, in IZSNU, examined); Zheng & OuCCCCC, 2004: 107; Zheng, 2005: 367; Deng Zheng & Wei, 2007b: 327; Deng, 2016: 283; Wei, Deng & Lu, 2019:1009; syn. nov.

Type material examined. Holotype Formosatettix torulosinota , ♀, larva, China: Yunnan prov., Weishan County, 13. June 1996, in IZSNU.

Notes. We examined the type specimen of Formosatettix torulosinota and found that it has hind wings. Therefore, it belongs to a winged pygmy grasshopper species other than Formosatettix . However, its hind wings have only radial venation, without cross-veins ( Fig. 2C ), indicating that it is a nymph. The type specimen of F. torulosinota is in poor condition with the abdomen and hind legs missing, but there is evidence indicating that it is a nymph. In the original description of Formosatettix torulosinota, Zheng & Mao (2002) provided a drawing showing that the antegenicular teeth of the dorsal margin before the knee of the hind femora were absent ( Fig. 2E ).

Formosatettix torulosinota ( Zheng & Mao, 2002) syn. n. represents a nymph of Bolivaritettix circocephalus . It has slightly truncate posterior angles in the pronotal lateral lobes, dense protuberances on the pronotal surface, obtuse humeral angle, interhumeral carina, and a narrow vertex.
