6) Pravdiniana Sergeev et Pokivajlov, 1992 ( Figs. 20 , 77, 81)

Characters. Pronotum moderately elongated, dorsally weakly depressed, with indistinct lateral keels, median keel raised on metazona; humeral excision absent. Ƥ subgenital plate elongated, with two lobes separated by a wide furrow; ovipositor short, its length is twice pronotum, curved at base at obtuse angle, ca. ½ hind femur; Ƥ VI–VII th sternites modified; hind femora/pronotum length Ƥ: 3.2–3.5; 3 unknown. Colour of lateral lobes of the pronotum is grayish bordered with a whitish stripe.

Remarks. The only species known is squamipterous. The shape of the pronotum, ovipositor and Ƥ subgenital plate are very characteristic; only one species has been described from Tajikistan, of which only the female is known ( Sergeev & Pokivajlov 1992).

Distribution. Tajikistan.

Note. This genus was named after the Russian orthopterist G.N. Pravdin.

Number of species known (after Eades et al. 2010): 1) mira Sergeev et Pokivajlov, 1992 (type species).

7) Modestana Beier, 1955 ( Figs. 6 , 56 , 97 , 109)

Characters. Head just larger than long, ratio maximum width/length of head (from vertex to clipeus): 1.1–1.2. Macropterous to squamipterous, pronotum rounded, humeral excision absent, keel not evident; Ƥ subgenital plate smooth with a deep excision of the hind margin; ovipositor whitish, long and gently curved upwards; Ƥ VI–VII th sternites not modified; hind femora/pronotum length 3: 3.8–4.0, Ƥ 3.8–4.1; 3 X th tergite with two pointed processes, separated by a wide incision, cerci apically flattened. Titillators slender and smooth. Colour of lateral lobes of the pronotum is blackish bordered with a white stripe.

Distribution. From Balkan peninsula to Italy.

Number of species known (after Eades et al. 2010): 3: 1) ebneri (Ramme, 1926) ; 2) kraussi (Padewieth, 1900) ; 3) modesta (Fieber, 1853) (type species).
