Pseudophylus stundjuki Yasunaga, 1999: 183 View in CoL (n. comb.).

Diagnosis. Male recognized by elongated body, laterally parallel, black dorsum; pale or yellow legs except red hind femur ( Figs. 1); J-shaped endosoma, secondary gonopore positioned subapically ( Fig. 6A). Detail descriptions provided by Yasunaga (1999).

Female: Not sexual dimorphic, color and texture similar to male, somewhat flat and sub-oval in shape. GENI- TALIA ( Fig. 6E): Genital structures membranous and transparent, sclerotized rings elongate, oval.

Measurements (♂ / ♀): (5/ 5): Body length 3.59–3.74/ 3.12–3.25; head width across eyes 0.72–0.78/ 0.67– 0.75; vertex width 0.29–0.32/ 0.32–0.36; lengths of antennal segments I–IV: 0.24–0.27, 1.07–1.11, 0.52–0.56, 0.37–0.41/ 0.20–0.24, 0.75–0.80, 0.43–0.48, 0.32–0.62; total length of labium 1.05–1.08/ 0.98–1.09; mesal pronotal length 0.60–0.62/ 0.57–0.61; basal pronotal width 1.10–1.16/ 1.10–1.12; width across hemelytron 1.31–1.40/ 1.41–1.47; and lengths of metafemur, tibia and tarsus: 1.02–1.15, 1.64–1.72, 0.39–0.44/ 0.96–1.06, 1.38–1.48, 0.37–0.41.

Specimens examined. North Korea: 1♂, Jangkang –do, Bosôk-ri , 1000m, 1.vi.1974, M. Josifov, det. by M. Josifov (SNU); 1♀, Tesong-san, Bei Phjongjang, 1.vi.1987, M. Josifov, det. by M. Josifov (SNU) . South Korea: Gyeonggi-do: 46♂, 50♀, Suwon-si, SNU Arboretum , 20.v.2009, on Pyrus ussuriensis Maxim. (Rosaceae), R. K. Duwal (SNU) .

Distribution. Japan (Hokkaido, Honshu), Korea (South), Russian Far East.

Discussion. Yasunaga (1999) cited this species as a serious pest on apples and additionally listed other hosts, Pyrus ussuriensis, Marus sieboldi ( Rosaceae ), Maackia amurensis (Leguminosae) and Artemisia sp. (Compositae) . In this current study, large numbers of specimens were collected from a individual of Pyrus ussuriensis Maxim. (Rosaceae) which was found seriously damaged. The field survey suggests that, they have one generation per year in Korea.
