Genus Monosynamma Scott, 1864

Monosynamma Scott, 1864: 159 (n. gen.); Kerzhner, 1988: 789 (key); Schuh, 1995: 357 (cat.); Kerzhner and Josifov, 1999: 374 (cat.); Yasunaga, 2001: 166 (diag.).

Type species: Monosynamma scotti Scott, 1864 (monotypy) (= Phytocoris bohemanni Fallén, 1829 )

Diagnosis. Generally recognized by elongated, sub-oval, entirely black body, black or fuscous or brown dorsum; pale inner margins of eyes, and base of vertex; broad pronotum; black or dark brown or brown femora with pale apices, pale or pale brown tibiae with dark brown spots; uniformly distributed simple, pale brown setae on hemelytron; simple S- shaped endosoma with two elongated apical processes ( Fig. 4A).

Distribution. Holarctic Region.

Discussion. Species of this genus are described as willow inhabitants and widely distributed to Holarctic region ( Wheeler and Henry 1992).

Diagnosis. Recognized by elongate, oval, and variously colored body (black, fuscous or brown with pale brown spots); pale inner margin of eyes and base of the vertex; most specimens with entirely black dorsum with two brown lateral spots on mesoscutum, or other individuals with numerous pale or brown spots, at base and center of pronotum, and mesially on scutellum, base of clavus and hemelytra, and base of cuneus ( Fig. 1); distinctly Sshaped endosoma, with two apical processes ( Fig. 4A).

Female: Not sexually dimorphic, color and texture similar to male except more flat and large in size. GENITA- LIA ( Figs. 4E–F): Bursa copulatrix with very large, symmetrical sclerotized rings; membranous and sclerotized structures observed on dorsal labiate plate furnished with numerous spinules ( Fig. 4F). Posterior wall with distinct inter-ramal lobe, laterally and centrally provided with semi sclerotized plate, furnished with numerous minute spinules ( Fig. 4E)

Measurements. (♂ / ♀). (5/ 5): Body length 3.58–3.84/ 3.68–4.32; head width across eyes 0.85–0.88/ 0.86– 0.91; vertex width 0.46–0.48/ 0.47–0.51; lengths of antennal segments I–IV: 0.24–0.29, 0.93–0.97, 0.49–0.52, 0.37–0.41/ 0.23–0.28, 0.85–0.96, 0.50–0.54, 0.40–0.43; total length of labium 1.36–1.39/ 1.34–1.41; mesal pronotal length 0.62–0.66/ 0.65–0.75; basal pronotal width 1.21–1.29/ 1.28–1.39; width across hemelytron 1.61–1.68/ 1.66–1.89; and lengths of metafemur, tibia and tarsus: 1.21–1.25, 1.71–1.82, 0.45–0.53/ 1.20–1.34, 1.90–2.02, 0.52–0.56.

Specimens examined. South Korea : Gangwon-do: 30♂, 68♀, Wonju-si , Munmak , 1.vi.2009, on Salix sp. (Saliaceae), R. K. Duwal and S. Jung .

Distribution. Azerbaijan, European continents, Japan, Korea, Kazakhstan, Mongolia, N. America, Russia.

Discussion. Large numbers of adults and nymphs were collected on Salix sp. (Salicaceae) along a small river bank. They were aggregated in some branches in shade with large number of ants.
