Type material. Neotype – male, RUSSIA: Primorskii krai, 40 km SE Ussuriysk, Ussuriysky Nature Reserve, 43°40’50” N, 132°32’45” E, grassy meadow at the edge of broad-leaved forest, 31 July 1993, coll. S.Yu. Storozhenko; here designated, deposited in the Zoological Institute of the Russian Academy of Sciences, St. Petersburg.
Description. Male (neotype). Body of large size for the genus. Head slightly shorter than pronotum; face in profile oblique. Frontal ridge slightly widened between antennae, narrow, 2.4 times narrower than vertex between eyes. Fastigium of vertex triangle; depression of vertex shallow with indistinct median carinula. Foveolae absent. Lower part of genae smooth. Eyes oval; vertical diameter of eye equal to subocular furrow. Antennae filiform, 23-segmented, reaching the base of hind femora, 2.4 times as long as pronotum; mid segments of antennae 2.8–3.0 times as long as width. Pronotum crossed by main transverse furrow; prozona 1.4 times as long as metazona; anterior margin of prozona rounded; posterior margin of metazona weakly excised near median carina; lateral carinae in prozona distinctly concave. Lateral lobes of pronotum 1.2 times as long as width. Prosternal process absent. Mesosternal lobes as wide as mesosternal interspace. Mesosternal interspace trapezoidal, 1.4 times as wide as long. Metasternal interspace transversal. Tegmina shortened, reaching the base of 5th abdominal tergite, not touching each other in a resting position, 1.8 times longer than pronotum and 2.9 times as long as wide, with obliquely truncate apex; costal field 4.2 times as wide as subcostal field. Hind wings vestigial. Hind femora narrow, 6.2 times as long as their maximal width; inner lower keel with 120–125 stridulatory pegs. Hind tibiae with 12 outer and 10–12 inner dorsal spines. Arolium broad, reaching the apex of claws. Tympanum large, oval. 10th abdominal tergite without furculae. Supra-anal plate triangular with shallow median longitudinal sulcus. Cerci conical, 3.0 times as long as their width near base. Subgenital plate pointed apically, 3.0 times as long as its height nears the base.
Epiphallus bridge-shaped; bridge narrow, arch-like; ancorae surpassing anterior projections; posterior projections short, with rounded apex; lophi large; oval sclerites absent. Cingulum sclerotized, consisting of broad apodemes, zygoma, and rami; zygoma broadly rounded apically. Valves of cingulum narrow, divided, apically pointed. Apical valves of penis with pointed apex, shorter than cingular valves; basal and apical penis valves connected by a narrow, strongly curved, and unbroken flexure.
Body from above brown, with blackish lateral stripe below lateral carinae of pronotum and lateral sides of abdominal tergites; from below body yellow. Head from above light brown with two blackish stripes from occiput to fastigium of vertex. Eyes dark brown. Antennae brown with blackish apex. Tegmina brown without any blackish stripes. Hind femora yellowish brown, lower and inner sides of femora yellow; knees dark brown. Hind tibiae light brown with brown base; spines light brown with black apex. Supra-anal plate brown with blackish apex. Cerci dark brown. Subgenital plate brown with greenish brown apex.
Measurements. Male (neotype), lengths in mm. Body: 23.5; pronotum 4.4; tegmen 8.0; hind femur 13.7.
Distribution. Russia: south part of Primorskii krai.
Remarks. The males of this species differ from almost all congeners in the lateral tegmina, which is not touching each other in a resting position, and similar in this aspect to P. squamopennis Lu, Wang et Ren, 2011 from Heilongjiang province of China. It differs from latter species by the shape of the tegmina, subgenital plate and cerci (in males of P. squamopennis tegmina scale-like, 2.1 times as long as wide, reaching 2nd–3rd abdominal tergites; subgenital plate short, 1.3–1.9 times as long as its height nears the base; cerci about 2 times as long as their width near base).
The female from Evseevka described as “ Podismopsis gynaemorpha?” by Ikonnikov (1911: 248) and the female from Iman (=Dalnerechensk, Primorskii krai) illustrated by myself as “ P. gynaemorpha ” (Storozhenko, 1986: 310, fig. 157, 2–5) are not conspecific with male and probably belongs to Podismopsis genicularibus (Shiraki, 1910), an extremely variable species widely distributed in the south part of the Russian Far East, Japan and Korea (Storozhenko et al., 2015).
