Phytocoris ohataensis Linnavuori, 1963

(Figs. 4 D–E, 5, 6E, 8, 10, 11, 13)

Phytocoris ohataensis Linnavuori, 1963: 74 (sp. nov.); Schuh, 1995: 896 (cat.); Kerzhner & Josifov, 1999: 158 (cat.); Yasunaga, 2001: 256 (diag.); Schuh, 2002–2014: (cat.).

Phytocoris scotinus Kerzhner, 1977: 8 (sp. nov.); Schuh, 1995: 906 (cat.); Kerzhner & Josifov, 1999: 159 (cat.); Yasunaga, 2001: 256 (diag.); Schuh, 2002–2014: (cat.); Yasunaga & Schwartz, 2015: 43 (diag. syn.).

Diagnosis. Recognized by its moderate size; dorsum pattern highly diverse, pale brown to dark brown, or green; long, slender right paramere (Fig. 10); male lobal sclerite leaflike, ovate (Fig. 11). Similar to P. minakatai, but easily distinguish by longer antennal segment III and labium (Figs. 4 D–E). In Korea, this species can be confused with P. intricatus, but can be distinguished by key (Couplet 6) below and the more ovate lobal sclerite. For more figures, diagnostic characters and description, see Kerzhner (1977, 1988a) and Yasunaga & Schwartz (2015).

Distribution. Japan, Korea, Far-East Russia.

Host plants. Adults were found from Abies sachalinensis F. Schmidt, Larix leptolepis (Sieb. et Zucc.) Gordon, Picea glehnii (F. Schmidt) Mast., P. abies (L.) H. Karst. P. pungens Engelm. (Pinaceae), Salix spp. (Salicaceae), Rhus javanica L. (Anacardiaceae) (Yasunaga & Schwartz, 2015); but immatures are yet to be found.
