Diagnosis. Posterior margin of vertex obtuse ( Fig. 2A, E View FIGURE 2 ). Mesonotum rhombic, carinae prominent and amberish ( Fig. 2A, E View FIGURE 2 ). Tegulae mostly yellowish. Tegmina with a thin brown strip from the middle half of the tip margin and a brown pterostigma ( Fig. 3A, B View FIGURE 3 ). Legs yellowish brown ( Figs 2C, D View FIGURE 2 , 3D, E View FIGURE 3 ). Apex of anal tube symmetrical in male with large right handed anal tube style ( Fig. 3A View FIGURE 3 ). Tooth on the left of the theca base long and tending forward from the middle with right angle ( Fig. 4E, G View FIGURE 4 ).

Description. Male (measurements in mm): body length, 9.35; mesonotum length, 2.21; mesonotum width, 2.12; pronotum width, 2.19; width of the vertex at the anterior margin, 0.57; length of the right tegmina, 7.97. Female: body length, 9.74; mesonotum length, 2.12; mesonotum width, 2.14; pronotum width, 2.12; width of the vertex at the anterior margin, 0.55; length of the right tegmina, 8.47.

Coloration. Generally, brown tones dominant. Pronotum and face carinae yellowish. Metope brownish, lateral carinae yellow, tapers to postclypeus, brownish part cuts the lateral carinae with a cuspidate formation in the first quarter of postclypeus ( Fig. 2B, F View FIGURE 2 ). Pronotal disc, postocular carinae and posterior of the dorsolateral margins of pronotum yellow; the anterior and the postocular region of pronotum, black. The adjacent margins to the mesonotum of tegulae black, the remaining parts completely yellow ( Fig. 2A View FIGURE 2 ). Legs yellowish brown. Tegmina veins yellowish at the base and darker towards the ends, brown; with a brown and narrow band from the bottom corner of the third to the upper corner of the eleventh to twelfth apical cell, lighter in female ( Figs 2C, D View FIGURE 2 , 3A, B View FIGURE 3 ). Females lighter in color, with a very small black spot in the middle of metope and postclypeus ( Fig. 2F View FIGURE 2 ).

Head. Macrocorypha length approximately equal to width. Lateral carinae of corypha looks like a helmet as a whole ( Fig. 2A View FIGURE 2 ), relatively narrow in female ( Fig. 2E View FIGURE 2 ) and split into three different parts, first quarter get closer each other and formed an acute arch-shaped carina anteriorly, second quarter parallel and remainder part diverge to posteriorly and formed an obtuse margin in posterior. Acrometope divided into two triangles by vague inverted V-shape carinae located in the middle of corypha’s anterior carina in dorsal view ( Fig. 2A View FIGURE 2 ). Metope 1.7 times as long as wide, with distinct median carina, fork of median carina small and indistinct and joint with postclypeus approximately at the level of antennae, postclypeus overflows a little towards metope in middle and metope towards postclypeus on sides ( Fig. 2B, F View FIGURE 2 ).

Thorax. Mesonotum square in shape, approximately equal in width to length, three times longer than pronotum and vertex combined, three carinae in the middle approximately parallel to each other, the outer ones diverging posteriorly, directed inward at an angle of 130° in the fifth (final) part ( Fig. 2A View FIGURE 2 ).

Wings. Longitudinal veins of tegmina, including the costal vein, with hairy tubercles, 3.3 times longer than wide with 11 apical and six subapical cells in male ( Fig. 3A View FIGURE 3 ), 12 apical cells in female ( Fig. 3B View FIGURE 3 ). Fork Sc+RP same level or slightly basad of fork CuA 1 +CuA 2 in male ( Fig. 3A View FIGURE 3 ), CuA 1 +CuA 2 basad in female ( Fig. 3B View FIGURE 3 ). Only RA, RP and MP 3+4 clearly forked for once in terminal in male ( Fig. 3A View FIGURE 3 ). MP 1+2 ended with three branches terminally ( Fig. 3A, B View FIGURE 3 ). RA and RP interconnected to each other with ir originated from the base of RA fork ( Fig. 3A, B View FIGURE 3 ). MP 1+2 and MP 3+4 connected with im terminated at the base of MP 3+4 fork ( Fig. 3A View FIGURE 3 ). Fork r-m closer to the base than m-cu and perpendicular to RP and MP ( Fig. 3A, B View FIGURE 3 ). And also with a brown and granulated pterostigma between the end of the CA and ScP+RA ( Figs 2C View FIGURE 2 , 3A, B View FIGURE 3 ).

Hind wing membranous and transparent, 1.75 times longer than wide ( Fig. 3C View FIGURE 3 ). ScP+RA, CuP and Pcu simple, RP just before the tip and CuA in the last third of the wing forked once, both ended with two terminals, MP forked twice and reaching the wing margin with three terminals, the first fork approximately same level with the fork of CuA, MP connected with RP by a relatively long r-m near the base of RP, r-m terminated just before first MP fork, the lowest branch of MP and the upper branch of CuA related with each other by the very short m-cu near the tip of the wing, r-m more basad than m-cu ( Fig. 3C View FIGURE 3 ).

Legs. Pro- and mesolegs simple. Profemur 1.68, protibia 1.2; mesofemur 1.49, and mesotibia 1.31 mm long. Metatibia with three in males and four in females lateral spines, and six apical teeth [can be formulated as 3+2+1 from inside to outside, cixius-type in Emeljanov (2002)]; first tarsomere without platellae but with eight teeth; second tarsomere with seven platellae and nine teeth ( Fig. 3D, E View FIGURE 3 ).

Terminalia . Anal tube symmetrical, with a large style at the anterior end. Anal style protruding from the notch at the tip and turns to the right dorsally ( Fig. 4A, B View FIGURE 4 ). Styli asymmetrical, left style longer than right one in natural position, the distal part of right style alike a rabbit head from ventrally (externally) and with a rectangular space between them in proximal half. The inner apical corner of the left style extends forward distinctly in the form of a thick finger ( Fig. 4C, D View FIGURE 4 ). Aedeagus has ten appendages ( Fig. 4E–G View FIGURE 4 ). Six of them located on the moving part of it, but only 3 of them seen from ventrally. The tooth seen from the ventrally and located at the left base of the aedeagus theca, at first extending and tapering to the left according to its natural position then turns towards the anterior at a right angle and ends with a long pointed tip ( Fig. 4G View FIGURE 4 ). Aedeagus with a lateral apophysis on the left side ( Fig. 4F, G View FIGURE 4 ). Distal upper end of the lateral apophysis with tooth, tooth beak looks like a scythe in laterally ( Fig. 4E View FIGURE 4 ). The remainder resembles the head and neck of a swan, with a clear opening between the tooth beak and the neck ( Fig. 4E View FIGURE 4 ).

Female genitalia primitive orthopteroid-type ( Fig. 5A View FIGURE 5 ). Posterior margin of pregenital sternite undulated three times, wide and regular ( Fig. 5C View FIGURE 5 ). Tergite IX moderately sclerotized, width about two times to length, ventral margins vaguely concave, with wax plate V-shape in caudal view ( Fig. 5C View FIGURE 5 ). Anal tube long, rectangular, slightly narrowed at apex, 1.64 times longer than wide in dorsal view; dorsal and ventral margins diverge to each other towards the end in lateral view, anal style clavate-shaped and extended forward from the anal tube ( Fig. 5B View FIGURE 5 ). Gonapophysis VIII and IX simple, needle-like, tips slightly curved to each other ( Fig. 5A View FIGURE 5 ). Ventral margin of gonoplac moderately sclerotized and rod-like, upper (inner) margin weakly sclerotized and lamellose, about three times longer than wide ( Fig. 5A View FIGURE 5 ).

Distribution. The species is only known from the type series collected in Kırşehir, Türkiye ( Figs 6 View FIGURE 6 , 7 View FIGURE 7 ).

Etymology. The species is named in honor of the first author’s wife.

Remarks. It is understood that P. eminei sp. nov. is closely related to P. major , P. megista and P. superans due to the symmetrical anal tube, the asymmetrical styli, aedeagus with lateral apophysis and with tooth on the left side of theca base as well as their distribution in adjacent geographic areas.
