Discussion. After comparing the two new described species by Yin & Shen (2021) and Liu et al. (2021), we conclude Eugryllacris binotata Liu & Bian, 2021 is a synonym of Eugryllacris tiga Yin & Shen, 2021 . Eugryllacris tiga Yin & Shen, 2021 is very similar to Eugryllacris vaginalis Pictet & Saussure, 1893 with regard to general habitus, size, and length of ovipositor, but differs from the latter in: face and pronotum with one pair of separated black spots, posterior margin of male subgenital plate with median lobe slightly wide, and posterior margin of female subgenital plate without median concavity. Eugryllacris vaginalis differs from Eugryllacris guomashan in: body slightly slender, posterior margin of male ninth abdominal tergite with 1 obtuse tubercle on both sides and below tubercle with 1 small hook; female subgenital plate shorter, posterior margin widely rounded with slightly deep concavity in middle; ovipositor shorter and obviously upcurved. Meanwhile, Eugryllacris tiga Yin & Shen, 2021 and Eugryllacris guomashan coexist in Mengla, but the former distributed broader, extending it to Cangyuan.
