(Figs. 253–264, 324–329)
Description. Male (holotype): Fastigium of vertex 1.3 times wider than width of eye. Antennal scapus 2.5 times narrower than fastigium of vertex; 2 times narrower than width of eye; 1.4 times narrower than frontal groove. Pronotum (Figs. 253–256) slightly convex in prozona; metazona flattened with relatively wide and blunt median carina; shoulder incision distinct as a concavity; anterior margin almost straight, posterior margin broadly rounded. Tegmina (Figs. 253–256) 1.2 times shorter than pronotum, reaching to end of 3rd abdominal tergite, in paratypes from the end of 2nd to end of 3rd tergites; in dorso-lateral view almost triangular, strongly narrowed and apex narrowly rounded. Femora (Figs. 253, 324) unarmed. Thoracic auditory spiracle long and narrow, in some males more elliptical. Last abdominal tergite (Figs. 257, 326) with relatively long, narrow and sharp posterior lobes and with deep median incision. Subgenital plate (Fig. 258) longer than wide, with a narrow triangular posterior incision, in some males slightly wider; styli long and slender, 1.9 times longer than the depth of posterior incision. Last 3 abdominal tergites with hairy dorsal surface. Cercus (Figs. 257, 327) slender, long and narrow, with inner tooth in distal part; apical part long and narrow triangular, very slightly recurved. Titillators (Fig. 328) slender; apical arms long, thin and slightly curved; basal arms strongly upcurved and widened; toothed middle part slightly convex.
Female: Fastigium of vertex 1.2 times wider than width of eye. Antennal scapus 2.35 times narrower than fastigium of vertex; 1.9 times narrower than width of eye; 1.3 times narower than frontal groove. Pronotum (Figs. 259–262) as in male, but shoulder incision more distinct. Tegmina (Figs. 259–262) 1.4 times shorter than pronotum, reaching to end of 2nd abdominal tergite, narrowly rounded at apex. Thoracic auditory spiracle long and narrow. Cercus simple, long and spine-like. Last tergite invisible in natural form because of wrinkling. Subgenital plate (Figs. 263, 329) almost square, with median carina and a weak furrow; posterior margin with relatively deep rounded incision. 6th and 7th sternites (Figs. 263, 329 slightly inflated, convex in lateral view. Ovipositor (Figs. 259, 264) slender, long and narrow, regularly and slightly upcurved along its length; almost twice as long as pronotum and 1.45 times shorter than hind femur.
Color. Body milky brown with brown and black markings. Antenna unicolor light brown. Behind of eyes (dorso-posteriorly) with 2 short, blackish brown bands. Face straw brown in male, slightly darker with reddish tone in female. Pronotum with distinct typical large spot on paranota, remaining part of pronotum straw brown in male, milky brown in female. Distal part of Sc and R darkened, all the other veins straw brown, cells mostly darkened with brown. Fore and mid femora with irregular blackish spots and short stripes. Inner and outer surfaces of hind femur with typical longitudinal dark bands; anterior end of dorsal surface with brown spots in two rows. Both sides of abdomen with indistinct brownish band anteriorly; dorsal surface with 2 near parallel bands along its length seems a single band with light midline. All sternites straw brown. Ovipositor as typical in subgenus, basal 1/3 ivory color, remaining apical part bright brown.
Diagnosis. This new species is recognizable by the male last tergite and the shape of ovipositor. It is different from Platycleis (Squamiana) sinuata Ramma, 1951 by the shape of shorter tegmina in both sexes with narrower distal part (tegmina clearly longer and distal part broader in P. sinuata, Figs. 248, 251), the narrower and longer thoracic auditory spiracle (distinctly wider and both ends rounded in P. sinuata), shape of male last tergite with slender, long, sharp lobes and deep incision (lobes distinctly shorter and wider; median incision shallower and more rounded in P. sinuata, Fig. 249), longer styli (much shorter in P. sinuata), shape of male cerci (shorter and wider in P. sinuata, Fig. 249), slender titillators (basal and apical arms distinctly shorter in P. sinuata) and the shape of clearly slender and longer ovipositor (ovipositor as in Figs. 250, 252 in P. sinuata).
Different from Platycleis (Squamiana) melendisensis Çıplak, 2002 by the clearly wider dorsal surface of pronotum (very narrow in P. melendisensis, Figs. 270, 272), shorter tegmina in both sexes (tegmina always distinctly longer than pronotum in P. melendisensis, Figs. 270, 272), the long, narrow and sharp lobes of male last tergite (shorter and wider in P. melendisensis), longer apical part of male cercus (cerci and last tergite as in Fig. 271 in P. melendisensis), shape of titillators (basal arms very narrow and slightly upcurved in P. melendisensis), female subgenital plate with deeper posterior incision, shape of longer ovipositor (ovipositor as in Figs. 273, 274 in P. melendisensis) and the larger size.
It is separated from Platycleis (Squamiana) salmani Çıplak, 2002 by the shape of tegmina with narrower distal part (distinctly wider in P. salmani, Figs. 265, 267), shape of male last tergite (lobes distinctly shorter and wider in P. salmani, Fig. 266), male subgenital plate with longer styli, shape of male cerci (inner tooth near to apex and apical part distinctly shorter in P. salmani, Fig. 266), shape of titillators (basal arms shorter, narrower and slightly upcurved in P. salmani), deeper posterior incision of female subgenital plate and the shape of longer ovipositor (ovipositor as in Figs. 268, 269 in P. salmani).
It is different from Platycleis (Squamiana) irritans Ramma, 1951 by the shape of shorter tegmina (longer and apex broadly rounded in P. irritans), male last tergite with slender, long and sharp lobes, shape of titillators (basal arms narrow and not upcurved in P. irritans), female subgenital plate with deeper posterior incision, shape of longer ovipositor (ovipositor of P. irritans very similar to P. sinuata).
The differences from Platycleis (Squamiana) weidneri Demirsoy, 1974 are similar that of P. sinuata.
