description: Saxetania (Mistshenkoella) gorochovi Ünal, sp. nov.
(Figs. 41, 326, 338–341, 839)
Type locality. Afghanistan: Kabul. Holotype: male (ZIN).
Material examined. AFGHANISTAN: Kabul, 1921, 1♂ (Holotype) (leg. P. Sergeev) (ZIN).
Description. Male (Holotype): Body (Figs. 338, 339) strongly compressed laterally. Fastigium of vertex (Figs. 338, 339) narrow and long, 1.6 times longer than wide, sloping, strongly depressed, with smooth surface, its lateral margins strongly raised. Vertex (Fig. 339) narrow between the eyes, 1.3 times narrower than vertical diameter and 1.2 times narrower than transversal diameter of eye; supraocellar and supraocular foveolae distinct, the latter closed type; median carinula very weak. Eye narrow, 1.5 times longer than wide. Frontal ridge almost with parallel sides, strongly diverged very near to clypeus, slightly incised just below the median ocellus. Antennae lost. Pronotum (Figs. 338, 339) strongly compressed laterally; lateral carinae absent; median carina strongly raised, arcuate; anterior margin strongly protruded as an acute angle, posterior margin prolonged posteriorly with a small median notch, reaching to half of tegmina; dorsal half of lateral view with distinct spiniform tubercles. Prosternum (Fig. 340) with a long, narrow median projection with bifid apex. Mesosternal interspace (Fig. 341) narrow, 1.5 times wider than its length and slightly narrower than mesosternal lobes. Tegmina (Figs. 326, 338, 339) brachypterous, reaching to half of 3rd abdominal tergite. Hind femur long and narrow, 3.2 times longer than its height, dorsal margin almost straight, with 9–11 distinct spines, ventral margin convex, slightly undulate; ventral margin of inner side smooth, without denticles. Hind tibia with 9 inner, 9 outer spines. Abdominal tergites (Fig. 338) simple, not raised and not protruded posteriorly. Tympanum large. Krauss’ organ absent. Apical valves of penis (Fig. 41 a) large, apex slightly curved backwards; apical end of basal valves of penis strongly protruded upwards from the middle of the arch of zygoma; tumida of zygoma distinct, tumida of cingulum indistinct (Figs. 41 a, b); posteromedian projection of epiphallus rounded at apex, with a weak median carina, pseudolophi separated, with 9 spines and spinules (Fig. 41 c).
Female: Unknown.
Coloration. Body greenish-cream with light cherry and black patters. Lateral carinae of frontal ridge and fastigium of vertex, lateral carinulae of vertex light cherry. Typical light bands on paranota very distinct, cream. Median carina and pronotal spiniform tubercles cherry. Dorsal and ventral carinae of outer surface of hind femur and spines of dorsal margin light cherry; inner surface of hind femur mainly yellowish-cream with distinct light cherry stains, ventral margin darkened; ventral surface reddish, inner margin darkened. Inner surfaces of hind tibia and tarsus orange-red with the inner sides of spines, turning to cherry-red ventrally, dorsal surface body color with outer spines and outer sides of inner spines. Tegmina pale greyish-green. Sternites creamish-yellow. Tympanal area and carinae cherry-red. Anterior parts of abdominal tergites pale greenish, posterior margins with narrow, transversal blackish-cherry bands; median carinae of tergites with a thin cherry stripe.
Diagnosis. This new species is distinguished from the other two species of the subgenus Mistshenkoella Cejchan by the strongly arcuate pronotum, (nearly straight to convex in S. gardezae, slightly convex in S. marani), the shape of prosternal projection with bifid apex (tongue-like apex in S. marani and S. gardezae), the shape of frontal ridge with parallel sides and slightly incised below the median ocellus (distinctly diverging and strongly incised below the median ocellus in S. marani and S. gardezae), the pseudolophi with 9 spines (14–16 spines in S. marani, more than 13–20 spines in S. gardezae), the orange-red hind tibia (wine red in S. gardezae, blue in S. marani). In addition the larger size and larger head (than S. gardezae), the pronotum 1.7 times longer than tegmina in the new species (1.2 times in the holotype, 1.4 times in the original description of S. gardezae), the apical end of basal valves of penis distinctly protruded upwards just above the posterior lobes of zygoma in lateral view (it is not protruded and not visible in lateral view in S. gardezae) are also different.
Measurements (mm). Holotype (male): body length 34.1; pronotum length 14.9; pronotum height 12.2; pronotum width anterior 7.4; pronotum width posterior 8.5; tegmina length 8.6; hind femur length 18.2; hind femur height 5.7.
Etymology. This new species is named in honor of my colleague and friend Dr. Andrej V. Gorochov (Zoological Institute of Russian Academy of Sciences) for his incredible contributions to Orthoptera as well as his support during this long term study.
