Diagnosis: Recognized by the large body ( Figs. 3, 4 ), the yellow-brown or deep brown hemelytron with the castaneous head, pronotum, mesoscutum and scutellum, the dense, appressed, sericeous setae and decumbent simple setae on the vertex ( Fig. 22 ), the distinctly appressed simple setae on the pronotum ( Fig. 23 ), the red or red-brown maxillary plate, buccula, and labial segment I, the red margin of the abdomen in the form of several obscure angled transverse traps, and the structure of male genitalia ( Figs. 26–30 ); separated from other species by the yellow-brown coloration of proximal 2/3 of hemelytron and the distinctive structure of projection on vesica.

The coloration of specimens collected from Heilongjiang Province which is greatly darkened, is rather similar to that of P. robustus sp. nov. ( Figs. 67–71 ), but easily recognized by the simple setae on dorsum and the form of male genitalia.

Redescription: Male ( Fig. 3 ): Macropterous, oval, broad, medium-sized.

Coloration: General coloration of body brown-castaneous, without markings; head deep brown in doral view, clypeus and mandibular plate yellowish brown, maxillary plate, and buccula red or reddish brown; labium yellow or yellow-brown with segment I red; antennal segment I pale-yellow with distally darkened to almost black, segment III and IV uniformly deep brown; pronotum brown; mesoscutum exposed, scutellum brown; hemelytron uniformly yellowish brown; mesepisternum and mesepimeron brown; all coxae pale-yellow, femora and tibiae yellow, tarsi dirty yellow with segment III darkened; abdomen red or reddish brown.

Surface and vestiture: Body generally smooth, pronotum and scutellum shining, hemelytron dull, mesepisternum polished and smooth. vertex and frons covered with dense, appressed, shining sericeous setae ( Fig. 22 ), lateral margin of head with several suberect or erect, relatively long, simple setae ( Fig. 22 ); pronotum with appressed simple setae, hemelytron covered densely with two types of setae, appressed, shining sericeous setae ( Fig. 23 ) scattered on proximal 2/3 of corium and subappressed, pale or light brown simple setae; mesepisternum and mesepimeron covered with a few sericeous setae, not forming a band or some patches; abdomen with declined, simple setae and sericous setae on segment IV and V.

Structure: Head ( Fig. 22 ): Triangular in dorsal and frontal views, clypeus and frons distinctly protuberant; vertex broad, flattened, posterior margin slightly concave, in the form of a complete carina; mandibular plate broad, weakly humped, maxillary plate flattened, buccula elongate and fusiform; labium reaching to median of mesocoxae, segment I stout with remainder slender; eyes kidney-shaped in lateral view, protuberant laterally; antennal segment I stout, weakly enlarged, segment II slender, bat-shaped, almost straight, segment III subequal to IV in length and diameter. Thorax: Pronotum broad, anterior margin weakly convex, finely conforming to posterior margin of vertex, lateral margin almost straight, posterior margin slightly concave mesially; mesoscutum exposed broad, weakly declined; scutellum flattened; hemelytron broad, exterior margin weakly convex posteriorly; cuneus slightly declined, lateral margin weakly rounded; coxae stout, femora weakly flattened, tibiae cylindrical, almost straight. Abdomen: Relatively broad and stout.

Male genitalia ( Figs. 26–30 ): Vesica L-shaped, with a median, lanceolate, spinelike projection with two tiny denticles basally and a thumblike process mesially ( Fig. 26 ); left paramere broad, boat-shaped with elongate hypophysis and blunt sensory lobe ( Figs. 27, 28 ); right paramere lanceolate, leaf-shaped ( Fig. 29 ); phallotheca stout with beak-shaped apex rather elongate ( Fig. 30 ).

Female ( Fig. 4 ): Macropterous. Surface and coloration similar to male, the size bigger than male, body broader.

Female genitalia: Structure as figure 31.

Host: Salix rorida .

Distribution: China (Heilongjiang, Hebei, Shandong, Nei Mongol, Gansu, Ningxia, Guizhou, Shaanxi), Far East of the USSR (Primorsk Territory), Mongolia.
