Body length 3.62/ 3.66−3.71; length from apex of tylus to cuneal fracture 2.49/ 2.55−2.67, width of head across eyes 0.77/ 0.76−0.77; width of vertex 0.41/ 0.41−0.46, lengths of antennal segments 0.23, 0.93, 0.66, 0.40/ 0.21−0.23, 1.03−1.05, 0.65−0.68, 0.38−0.41; mesal length of pronotum 0.65/ 0.61−0.66; basal width of pronotum 1.25/ 1.29−1.31; maximum width across hemelytron 1.62/ 1.67−1.68; and lengths of metafemora, tibiae and tarsus 1.14, 1.92, 0.55/ 1.30−1.32, 1.84−1.93, 0.53−0.54.

Distribution. Korea (North, South*).

Specimen examined. South Korea: 1♂, 2♀, Gyeonggi-do, Gapyeong-gun, Cheongpyeong-myeon, Samhoeri, Mt. Hwaya, 29.v.2014, on Prunus sp. ( Rosaceae), R.K. Duwal (SNU).

Remarks. Psallus sanguinarius was previously reported in North Korea from Sorbus amurensis (Rosaceae) and Picea (Pinaceae) (Josifov, 1983). We were unable to observe any specimens during our previous study (Duwal et al. 2012). Fortunately, we could add few recently collected specimens of this species on Prunus (Rosaceae) from northern part of South Korea. The images of dorsal habitus, and male genitalia are given in figure plates, 1A-B and 4C respectively. (For details see, Josifov, 1983: 206, 209−210).
