Edentatettix leyeensis Deng, sp. nov., here designated.	en	Li, Yuemei, Leng, Shixiong, He, Jiasong, Deng, Weian, Guan, Delong (2025): Mitochondrial phylogenomics of pygmy grasshoppers (Orthoptera, Tetrigidae, Metrodorinae): descriptions of a new genus, two new species, and new synonyms from China.

1770533B3E00596D990FEE51FA71EB1D.taxon	diagnosis	Diagnosis. The new genus can be easily distinguished from other genera of Metrodorinae by the saw-like teeth of the female ovipositor absent (Fig. 8 G). Edentatettix is allied to Macromotettixoides Zheng, Wei & Jiang, 2005, but differs as follows: head and eyes slightly exserted above pronotal surface (not exserted in Macromotettixoides), dorsal surface of pronotum low and flat and tectiform is not obvious (distinctly tectiform in Macromotettixoides), saw-like teeth of female ovipositor absent (present in Macromotettixoides). Edentatettix is also similar to Concavetettix Deng, 2021 but differs from the latter by the obtuse projection under each lateral carina of the prozona absent (present in Concavetettix), dorsum of pronotum flat and slightly depressed in the middle part between the shoulders (dorsum of pronotum with irregular concavities in Concavetettix), saw-like teeth of female ovipositor absent (present in Concavetettix).	en	Li, Yuemei, Leng, Shixiong, He, Jiasong, Deng, Weian, Guan, Delong (2025): Mitochondrial phylogenomics of pygmy grasshoppers (Orthoptera, Tetrigidae, Metrodorinae): descriptions of a new genus, two new species, and new synonyms from China.
