Abdomen: black with blue sheen; tergite 1 with a few yellow scales medially; tergites 2−7 each with a narrow yellow stripe distally; sternum 2 yellow, others each with a narrow yellow stripe distally; anal tuft black with blue-violet sheen, ventrally yellow-orange. Forewing. Basally black; costal margin dark brown to black, with a narrow yellow stripe between vein Sc and R-stem; discal spot and veins within exterior transparent area dark brown to black; apical area orange with admixture of brown scales; discal spot broad, exterior transparent area large divided into five cells, level to M2 about 3X as broad as discal spot and 0.8X as broad as apical area; posterior transparent area reaching distal margin of discal spot; fringe brown. Hindwing transparent; veins, discal spot black, small, cuneiform, reaching to vein M2; fringe dark brown, yellow anally. Female (Fig. 2). Antenna length 7.0 mm; forewing length 9.5 mm; body length 10.6 mm. Labial palpus yellow-orange; hindwing outer margin yellow, broad, about 1−2 times as broad as fringe; yellow anally; yellow band on tergite 4 wider; sterna yellow; anal tuft orange laterally. Genitalia. Male (Gen. Prep. JYL-009, NTNU, Fig. 16). Tegumen-uncus complex relatively narrow; scopula androconialis well-developed, long, about as long as tegumen-uncus complex; crista gnathi medialis long and narrow, semi-oval, membranous proximally; crista gnathi lateralis semi-oval, narrow and short, membranous; valva elongated oval; crista sacculi poorly developed, covered with setae as most part of valva; ventral crista low and short, covered with relatively short flat-topped setae; saccus broadened and rounded basally, nearly as long as vinculum; phallus extremely narrow about 2/3 length of valva; vesica with numerous, irregular, minute cornuti. Female (Gen. Prep. JYL-010, NHM, Fig. 24). Apophysis posterior about as long as apophysis anterior; lamella antevaginalis well-sclerotized; antrum narrow, opening at level of anterior-dorsal margin of 8th tergite, narrow, membranous; ductus bursae narrow, long, membranous; corpus bursae membranous, ovoid, without signum. Diagnosis. A distinctive species. P. dortmundi sp. nov. is similar to P. formosicola (Strand 1916) which was described from the Taiwan. P. dortmundi may be distinguished from P. formosicola by forewing base black instead of yellow. Outer margin of exterior transparent area is nearly truncate in P. dortmundi, but convex in P. formosicola. Hindwing outer margin of female is yellow in P. dortmundi, but black in P. formosicola. The saccus is rounded in P. dortmundi, but forked in P. formosicola. Etymology. Wing patterns of adult resemble the logo of German soccer team of Dortmund. Biology. The larvae host plant is unknown. Moths were collected in June and October from flowers of Ampelopsis brevipedunculata (Vitaceae) and Bidens pilosa (Asteraceae). Distribution. Known only from Taiwan.
