Phytocoris intricatus Flor, 1861: 593 , 603 (sp. nov.); Josifov & Kerzhner, 1972: 16 (distr.); Schuh, 1995: 886 (cat.); Kerzhner & Josifov, 1999: 157 (cat.); Zheng et al., 2004: 485 (diag.); Schuh, 2002–2014: (cat.).

Diagnosis. Recognized by its moderate size; brown to dark-brown body; dorsum matte, more or less mottled; labium short, slightly over metacoxa. In Korea, P. ohataensis and P. minakatai shows similar appearance, can be distinguished by below key (couplet 6), slender and elongated lobal sclerite of male genitalia, more widened right paramere ( Figs. 7 , 9 ). For more diagnostic characters, description and figures, see Wagner & Weber (1964) and Kerzhner (1988a).

Redescription. Body moderate to rather large, elongate oval, subparallel sided; basic coloration copper brown to fuscous; dorsal surface matte, partly glossy, with white sericeous, reclining pubescence and dark, simple, semierect setae. Head oblique, covered with pale, minute suberect setae; clypeus brown or reddish brown, with irregular, symmetrical dark markings; frons slightly rugose; vertex narrow, eye width subequal to width of vertex in male. Antenna copper brown, slender; segment I highly mottled with brown spot, with long, semierect setae; base of segments II and III pale. Labium glossy and brownish, segment IV darkened; reach over metacoxa to sternum V. Pronotum Chestnut brown to dark brown; fuscous line traverse medially, not obvious at dark specimen; posterior part usually dark brown; posterior margin pale; calli brown to pale brown, slightly tumid, rugose; collar usually brown, rounded; scutellum rather tumid, pale brown to copper brown; pleura widely darkened, ventral margin and ostiolar peritreme pale yellow. Hemelytron generally brown to dark brown, mottled; posterior part of corium pale, with a pair of dark, oblique marks; cuneus dark brown, basal 1/3~1/4 pale spotted, often tinged with red basally; membrane grayish, with irregularly speckled pale spots; vein dark brown. Leg slender, dark brown; coxae and trochanters pale yellow; meso- and metacoxa tinged with brown basally; femora rather flat, speckled with pale spots; basal 1/4 pale yellow; each tibia with three or four pale rings, metatibia vaguely annulated; apex of protibia and extreme apex of mesotibia unicolorously copper brown. Abdomen entirely darkened in male, rarely with pale portion; female abdomen dark brown laterally, medially pale. Male genitalia as in Figs. 7 , 9 , Female genitalia as in Fig. 12 .

Distribution. Europe, Korea, Far-East Russia.
