Dicyphus miyamotoi Yasunaga 2000: 100 .

Diagnosis. Adult: recognized by yellowish green, elongate, slender body ( Fig. 1 View FIGURE 1 A); uniformly distributed simple, suberect, dark brown setae on dorsum ( Fig. 1 View FIGURE 1 C); dark brown clypeus, pale mesial and extreme apex of the antennal segment II; immaculate hemelytra; rows of obscure spots on all femora, tibia with well–developed spines ( Fig. 2 View FIGURE 2 A–B), and dark tarsal segments; evaporatory area well–developed, swollen with one long seta ( Fig. 2 View FIGURE 2 D–F), and pulvilli setiform; pseudopulvilli fleshy blunt with one side of apex extended to form leafy apically ( Fig. 2 View FIGURE 2 C). Male genitalia. Long setae on left paramere and simple vesica ( Fig. 1 View FIGURE 1 D–E). Female genitalia ( Fig. 3). Bursa compulatrix very transparent, sclerotized rings thick rimmed, more or less triangular; posterior wall with chitinous plate centrally; an inverted vase-shaped semi–sclerotized membrane followed by the interramal sclerite furnished with numerous minute spines. Nymph (5th stage): eyes reddish brown; antennal segments II–III dark brown on basal half, the remainder pale green; rostrum segment IV dark brown at apex; apex of tibia and whole tarsi dark brown ( Fig 1 View FIGURE 1 B).

Gyeonggi–do: 113, 7Ƥ, Mt. Gwanggyo, Suwon–si, 23.V.2003, light trap, J. Seong leg.; 113, 6Ƥ, Suwon arboretum, Suwon–si, 7.VII.2003, on Rosa multiflora Thunb (Rosaceae) , J. Seong leg.

Distribution. South Korea (new record); Japan (Shikoku, Honshu, Kyushu).

Biology. In Korea, this species was collected from wild roses ( Rosaceae ) such as Rosa multiflora Thunb. , Rosa rugosa Thunb. , and Rosa davurica Pall , and was commonly attracted to light. During field surveys and laboratory observations nymphs and adults together were found feeding on the aphid Sitobion ibarae (Matsmura 1917) ( Fig. 1 View FIGURE 1 A–B).
