Diagnosis: Eremippus weidneri Demirsoy, 1977 differs from the genus Eremippus Uvarov, 1926 in several characters. These characters are the following: head not ascending in E. weidneri Demirsoy, 1977 (in Eremippus Uvarov, head distinctly ascending), facial carinulae indistinct (in Eremippus facial carinula slightly distinct), face not very oblique (in Eremippus face very oblique), frontal ridge forming broadly rounded with the fastigium of vertex (in Eremippus frontal ridge forming an acute angle with the fastigium of vertex), fastigium of vertex nearly smooth or slightly sulcate and margins not raised (in Eremippus fastigium of vertex deeply sulcate, margins raised), temporal foveolae visible from above, about 2.3–3.5 as long as broad and same width throughout (in Eremippus temporal foveolae only partly visible from above and about almost 2.5 times as long as broad and narrowed anteriorly), medial field without irregular false vein (in Eremippus medial field with irregular false vein), first and second cubital field nearly indistinct (in Eremippus first and second cubital field distinct).
On the other hand, Eremippus weidneri Demirsoy, 1977 shows more morphological similarities to the genus Stenobothrus Fischer, 1853 than other genera of Gomphocerinae (see Table 1). The given morphological characters in Table 1 are the same as those of Stenobothrus. Therefore, Eremippus weidneri Demirsoy, 1977 is transferred from the genus Eremippus Uvarov, 1926 to the genus Stenobothrus Fischer, 1853.

Redescription-Supplement to Description by Demirsoy (1977) Based on New Material from Type Locality. Head. Face strongly oblique from vertex toward clypeus (Figs. 3 A, 4A); frontal keels straight near the antenna and feebly divergent downward (Figs. 3 B, 4B). Vertex higher than compound eyes with median keel; fastigium of vertex wide, short, slightly incised. Foveolae short, 2.3–3 times longer than wide in male (Fig. 3 D), 3– 3.5 times in female (Fig. 4 D). Vertical diameter of eye/minimum width of vertex between eyes 1.75–2.15 in male, 1.35–1.52 in female; vertical diameter of eye/length of subocular groove 1.6–2.1 in male, 1.5–1.6 in female. Antennae longer than head plus pronotum length in male, reaches third transversal sulcus in female, its longest medial segment 1.3–1.5 times as long as wide in male (Fig. 3 E), 1.3–1.4 in female (Fig. 4 E).
Pronotum. Frontal nearly straight, caudal margins of disc triangular in both sexes. The maximum/minimum width between lateral keels 1.5–2.75 in both sexes (Figs. 3 C, 4C). Third transversal sulcus straight or indistinctly curved. Internal margins of the mesosternal lobes divergent backward and 2–2.5 times wider than long medially in male, 1.3–1.6 times in female. The length of hind femur 3.8–4.7 times longer than of its maximum width in male, 3.7–4.4 in female.
Tegmina. Reach to end of 7th abdominal tergum or tip of the cerci in male, reach to end of 3th or end of the 4th abdominal tergum in female; 2.8–3.5 times as long as wide in male (Fig. 3 F), 2.6–2.8 times in female (Fig. 4 F). Precostal area reaches from 8/10 to 9/10 the length of tegmina in both sexes. Maximum width of costal area 0.6– 0.7 times wider than the maximum width of the precostal area in male, 0.8–0.95 times in female; maximum width of costal area 0.75–0.90 (1.6) times wider than the maximum width of the subcostal area in male, 1.7–2.6 times in female; costal, subcostal and radial vein nearly straight. Medial ones are distinctly widened, maximum width of it 2.3–3 times wider than the maximum width of costal area in male, 2–2.6 times in female. First cubital vein and second cubital vein generally fused along the tegmina. Stigma absent. Alae slightly shorter than the tegmina in both sexes.
Abdomen. Tympanal opening slit-shaped, 6–8 times as high as wide in the middle in male, 6–10 times in female. Male subgenital plate upcurved; cerci not reach to apex of anal tergum in both sexes, length of cerci 2–2.5 times longer than the greatest width in male (Fig. 3 G), 1.3–1.5 times in female (Fig. 4 H). Epiphallus triangular shapes (Fig. 3 H). Dorsal valves of penis longer than cingular valves. Dorsal and ventral valves of the ovipositor notch nearly in apical (Figs. 4 G, 4I).
Coloration. Brownish-green dorsally and yellowish ventrally in general appearance. Vertex with light brown or blackish around the carina; from 1th to 5th abdominal tergum blackish dorsally in male and from 1th to 7th abdominal tergum blackish laterally in female. Tegmina in body color. Subgenital plate reddish in male and from 8th to 10th abdominal terga reddish in female. Hind femur reddish brown; hind tibia yellowish.
Measurements (in mm). Length of male body 11–12 in male, 14–16 in female; head 2–2.3 in male, 2.5–2.8 in female; pronotum 2.2–2.4 in male, 3–3.5 in female; tegmina 6.5–7 in male, 4–4.5 in female; hind femur 7–7.5 in male, 8.2–9.5 in female.
Male calling song. A total of 6 records from three males were analyzed from Ordu, Çambaþý upland, near Yeþilce town, 1891 m, 4.7.2013 (Fig. 1), Turkey (recorded at 33–38 °C in Lab.).
The calling song comprises one or two (rarely) phrases. The phrase duration varies between 1.7 and 3.4 s (2.23 ± 0.61; n=8) and a phrase consists of 15–33 (23.37 ± 4.73) regular syllables following with interval of 9–52 ms (24 ± 4.38), (Fig. 5 A). The syllables are repeated with a period of 63–116 ms (92.68 ± 11.88) but almost constant within each phrase. Oscillographic analyses show that each syllable consists of 4–6 (5.02 ± 0.78) separate pulses (Fig. 5 B). The syllables at the beginning of the phrase (first and second syllables) include 2–3 pulses. The first pulse of syllable longer than the other pulses (Fig. 5 C) and its duration varies between 11–42 ms (32.98 ± 3.87) while others vary between 2–5 ms (3.27 ± 0.98).
