Deng, Wei-An, Luo, Jie-Ling, Huang, Chao-Mei & Lin, Li-Liang, 2023, Review of the genus Formosatettix Tinkham (Orthoptera: Tetrigidae) with description of new taxa, new synonymy and an updated key to species, Zootaxa 5228 (3), pp. 201-243 : 219-220

7. Formosatettix latifemurus Deng , nom. nov. ( Figs. 10 , 24I )

Formosatettixoides yunnanensis Zheng & Mao, 1997: 6 [description] (holotype — ♀, China: Yunnan prov., Dali County, Cangshan (Huadian), in IZSNU, examined); Zheng, 2005: 371; Deng, Zheng & Wei, 2007: 329; Zheng, Mao & Xu, 2010: 5; Zha & Zheng, 2014: 542; Deng, 2016: 285.

Type material examined. Holotype, ♀, China, Yunnan prov., Dali County, Cangshan (Huadian), 08 August 1995, IZSNU; paratypes, 1♁ 1♀, the same data as holotype, IZSNU.

Notes. Formosatettixoides yunnanensis has a posterior margin of the lateral lobe of pronotum only with ventral sinus and tegminal (upper) sinus absent; tegmina and hind wings reduced to minute scales completely hidden under pronotum, and it belongs to the genus Formosatettix . This species can be identified by the smooth body; the vertex is much wider than one of the eyes; the pronotum is strongly elevated and arch-like; the anterior margin of the pronotum is obtuse and protruding; the apex of the hind pronotal process is concave; the middle femur is much wider than the fore femur.

Zheng (1992) described Formosatettix yunnanensis Zheng, 1992 from Yunnan (Pingbian). Here, Formosatettixoides yunnanensis Zheng & Mao, 1997 is moved to the genus Formosatettix . Formosatettix yunnanensis Zheng & Mao, 1997 must therefore be renamed as a secondary homonym based on the rule of Article 57.3 of the International Code of Zoological Nomenclature ( ICZN 1999).

Etymology. The specific epithet is derived from “ latifemurus ”, meaning width of middle femur is much wider than one of fore femur.

Distribution. China (Yunnan).
