Physopleurella obscura Poppius 1909: 13 (syn. Esaki 1926: 170). Scoloposcelis japonicus Esaki 1931: 263 –264 (syn. Hiura 1959: 7). Diagnosis. Antenna ( Fig. 2 A) yellowish brown, with apex of segment I dark brown; segment II longer than head width across eyes; rostrum ( Fig. 2 B) dark brown; pronotum ( Fig. 2 A) yellowish brown; scutellum reddish brown; hemelytra yellowish brown with innermost portion of corium narrowly darkened; cuneus broadly darkened. Pygophore ( Fig. 3 B) with a nearly straight paramere, slightly bent anteriorly at apex. Description. Body ( Fig. 2 A) generally brown. Head dark brown, slightly shorter than its width across eyes; dorsal surface sparsely covered with long, silky, erect setae; tylus dark brown; vertex about 1.5 as wide as eye; eyes black, not touching anterior margin of pronotum; ocelli reddish brown. Antennae yellowish brown; segment I nearly reaching apex of head, with sparse short setae; segment I dark brown at apex, segment II dark brown on one third apically, a little longer than head width across eyes, clothed with suberect setae; segment III about one third as long as segment II, and slightly shorter than segment IV; segment IV weakly flattened; lengths of segments I–IV (3/Ƥ, ranges in mm) 0.14–0.15/0.15– 0.17, 0.53–0.58/0.55–0.57, 0.33–0.35/0.31–0.36, and 0.30–0.31/0.28–0.33, respectively. Rostrum stout, short ( Fig. 2 B), reaching to collar, sparsely covered with short setae; segments I to IV fuscous, except IV at apex; segments III slightly longer than segment IV,; lengths of segments II–IV (3/Ƥ, ranges in mm) 0.08–0.09/0.08–0.09, 0.23–0.25/0.21–0.26, and 0.19–0.21/0.19–0.23, respectively. Pronotum brown, tinged with dark brown posteromedially, covered with long, silky, reclining setae; collar narrow, with short setae; lateral margin sinuate, carinated on anterior 2/3; posterior margin about three times as wide as anterior margin. Scutellum darker than pronotum, weakly shiny, with two distinct foveae at middle. Hemelytra light brown, covered with yellow, reclining setae; cuneus widely darkened; apical part of corium almost three times as wide as embolium; membrane grey, with several veins. Osiolar peritreme and evaporative area brown; ostiolar peritreme short, slightly curved backwards. Legs pale yellow, densely covered with yellow, short setae; fore femur with two series of spines ventrally, composed of long and short spines. Male genitalia as shown in Fig. 3 B. Pygophore with a nearly straight paramere, slightly bent anteriorly at apex. Female genitalia with greatly reduced ovipositor. Measurements (3/Ƥ, ranges in mm). Body length 3.25–3.40/3.45–3.88; head length (excluding neck) 0.45–0.48/ 0.41–0.52; width (including eyes) 0.44–0.47/0.47–0.51; vertex width 0.14–0.16/0.16–0.23; width between ocelli 0.08– 0.09/0.11–0.12; anterior pronotal width 0.32–0.36/0.31–0.36; mesal pronotal length 0.44–0.45/0.46–0.47; basal pronotal width 0.98–0.99/1.11–1.16; length of embolial margin 0.90–0.93/0.91–0.94; length of later cuneal margin 0.63–0.64/ 0.66–0.69; maximum width across hemelytra 0.78–0.81/0.81–0.87.

Australia , China , Japan , Hawaii, Korea , New Guinea , Philippines , Thailand , Vietnam . Biology. To date, this species has been found only on islands or along the coastal area in South Korea . Contrasting with the other Korean flower bugs ( Amphiareus , Orius , Anthocoris , etc.), this species has never been collected from winter hibernating habitats. This species was collected by beating dead-leaf clusters of various kinds of trees, together with small arthropods which appeared to be their prey ( Fig. 3 B). The new record of this species from the Korean Peninsula is the northern limit of its distribution, as this species is distributed mainly in tropical regions ( Yamada and Hirowatari 2007b ).
