10. Formosatettix nyalamensis ( Zheng & Lin, 2015) , comb. nov. ( Figs. 12 , 24M )

Aalatettix nyalamensis Zheng & Lin, 2015: 490 [description] (holotype — ♀, China: Xizang autonomous region, Nyalam County, Quxiang, in IZSNU, examined); Deng, 2016: 266.

Type material examined. Holotype, ♀, China, Xizang autonomous region, Nyalam (Quxiang), 19 August 2014, IZSNU; paratype, 1♀, the same data as holotype, IZSNU.

Notes. This species is not a representative of the genus Aalatettix because the posterior margins of lateral lobes of pronotum only with ventral sinus and tegminal (upper) sinus absent; tegmina and hind wings are invisible (“vestigial” type). It belongs to the genus Formosatettix . Formosatettix nyalamensis is easy to identify: the width of the vertex between the eyes 1.6 times the width of a compound eye; pronotum compressed and distinctly tectiform, its surface with sporadic small tubercles; anterior margin of pronotum obtuse protruding; lower margin of hind process straight.

Distribution. China (Xizang).
