(Figs. 1 F, 4G–H, 5, 6G, 8, 10, 11, 13)

Phytocoris shabliovskii Kerzhner, 1988b: 38 (sp. nov.); Schuh, 1995: 907 (cat.); Kerzhner & Josifov, 1999: 160 (cat.); Zheng et al., 2004: 525 (diag.); Schuh, 2002–2014: (cat.).

Diagnosis. Recognized by its rather small to moderate size; highly mottled dark-brown dorsum; basally pale cuneus, and apically pale pro- and mesotibia. It can be confused with P. longipennis, from which it is easily distinguished by shorter appendages (Figs. 1 F, 4G–H, 5) and the genital structures as diagnosed by Yasunaga & Schwartz (2015). For more diagnostic characters, see Kerzhner (1988a, b).
