Massa, Bruno & Fontana, Paolo, 2011, Supraspecific taxonomy of Palaearctic Platycleidini with unarmed prosternum: a morphological approach (Orthoptera: Tettigoniidae, Tettigoniinae), Zootaxa 2837, pp. 1-47 : 19

24) Eumetrioptera Miram, 1935 ( Figs. 24 , 62 , 85 )

Characters. Micropterous, pronotum rounded, not excised, almost laterally triangular, median keel obliterated; Ƥ subgenital plate short, with median furrow, lobes reduced, truncate; ovipositor sickle-shaped, broad and regularly curved; Ƥ VII th sternite with two tubercles near the hind margin; hind femora very short; 3 cerci thick with subapical tooth. Colour of lateral lobes of the pronotum is black bordered with a wide white stripe.

Remarks. Generally authors consider it a subgenus of Platycleis . The shortness of hind femora and the pronotum shape seem useful characters to separate definitively it from Platycleis .

Distribution. Central Asia.

Number of species known (after Eades et al. 2010): 6: 1) beybienkoi (Bezukin, 1978) ; 2) crassa Mishchenko, 1949 ; 3) mistshenkoi (Bekuzin, 1961) ; 4) monochroma Bei-Bienko, 1947 ; 5) obuchovae Mishchenko, 1949 ; 6) pavlovskyi Miram, 1935 (type species).
