(Figs 3, 4, 8)
Type Material. Holotype: ♂, China, Tibet autonomous region, Linzhi, Bomi county, Tongmai town, 30°05’49.44” N, 95°04’01.07” E, 20–VII–2018, 1800 m, Tianpeng Chen leg. (SCAU). Paratype: 1♂, China, Tibet autonomous region, Medog county, Beibeng, 29°14’11.28” N, 95°09’51.52” E, 25–VII–2017, 1731 m, Tiantian Yu leg. (SCAU).
Description. Holotype (Figs 3, 4). Alar expanse 30 mm; body length 18 mm; forewing 14 mm; antenna 7 mm.
Head: antenna black with dark brown sheen; frons and vertex dark brown with brown sheen; basal segment of labial palpus white, with a few yellow scales basally, mid segment white, apical segment pale yellow; proboscis present; pericephalic scales dorsally black with brown sheen, white laterally.
Thorax: patagia and tegula blackish brown with dark brown sheen. Forewing dark brown with purple sheen; ETA semi-transparent. Hindwing covered with yellowish semi-transparent scales, with pale violet sheen; discal spot not developed; veins and outer margin blackish brown; cilia dark brown with bronze sheen. Legs with fore femur ventrally yellow, with a few white scales distally; distal half of fore tibia brick-orange dorsally, ventrally mixed with yellow scales; fore tarsus dark brown dorsally, pale brown ventrally; mid and hind coxae yellowish white; mid and hind femora blackish brown with dark brown sheen; distal half of mid tibia covered with brick-orange hairs both dorsally and externally; mid tarsus with a few brick-orange scales dorsally, greyish white ventrally; hind tibia with a brick-orange spot distally, scattered with greyish white scales both ventrally and interiorly; spurs blackish brown; hind tarsus dorsally dark brown with a few brick-orange scales, yellowish white ventrally.
Abdomen: black with dark brown sheen; tergite 1 with a few dark yellow scales anteriorly; tergite 2 with a dark yellow spot on each side; tergites 3–7 each with a narrow yellow stripe posteriorly; anal tuft small, yellow dorsally, pale yellow ventrally; sternites 3–7 with yellowish white stripes at posterior margin.
Male genitalia (Fig. 8). Uncus finger shaped, strongly sclerotized and apically pointed; tegumen well-developed, relatively broad; valva broad, rounded distally, scattered with a few simple setae interior-ventrally; saccus short and rounded; phallus short, relatively broad; coecum penis short; vesical with numerous minute spinules.
Female unknown.
Diagnosis. P. polyzona sp. nov. is similar to P. taiwana based on external features. However, it is easily separated by the coloration of the pericephalic scales (dorsally black with brown sheen, white laterally in P. polyzona sp. nov., dorsally orange, laterally white in P. taiwana), the blackish brown metathorax (with two small yelloworange spots submedial-posteriorly in P. taiwana), the coloration of the abdomen (tergite 2 with a dark yellow spot laterally on each side, tergites 3 and 7 each with a dark yellow stripe posteriorly, sternites 3–7 with yellowish white stripes posteriorly in P. polyzona sp. nov., tergite 2 without yellow spots laterally but with narrow pale yelloworange stripe posteriorly, tergites 3 and 7 without yellow stripe, only sternite 4 with a narrow pale yellow-orange stripe in P. taiwana), the yellow anal tuft (dark brown in P. taiwana), and the smaller cornuti (with larger thornshaped cornuti in P. taiwana). Superficially, this new species is also close to P. similis but can be distinguished by the antenna (entirely black with dark brown sheen in P. polyzona sp. nov., dark brown, mixed with orange scales in distal half in P. similis), the coloration of the pericephalic scales (dorsally black with brown sheen, white laterally in P. polyzona sp. nov., dorsally orange to pale orange, laterally slivery-white in P. similis), the patagia (entirely black in P. polyzona sp. nov., dark brown, mixed with orange scales laterally in P. similis), the abdomen (tergite 2 with a dark yellow spots laterally on each side, tergite 3 with a narrow yellow stripe, sternites 3–7 with yellowish white stripes posteriorly in P. polyzona sp. nov., tergite 2 without yellow spots laterally but with orange stripe posteriorly, tergite 3 dark brown, only sternites 4 and 5 each with a narrow brick-orange stripe in P. similis) and the characteristic structure of the vesica (with numerous, very small cornuti in P. polyzona sp. nov., with numerous larger cornuti in P. similis).
Distribution. Known from Bomi and Medog county, Tibet, China.
Remark. All the specimens were collected in the noon. The holotype was collected at the edge of montane forest, close to the Tongmai long-span bridge. The paratype was attracted to pheromone lures at the edge of montane forest in Beibeng. The pheromone lures were produced by Anglian Lepidopterist Supplies Company (Station Road, Hindolveston, Norfolk, UK).
Etymology. The name of the new species derived from a noun of Latin origin, zona = marking, plus an adjective of Latin origin, poly = many, meaning many stripes of the abdominal tergites.
Molecular data. The barcode of Paradoxecia polyzona sp. nov. (658 bp fragment of COI; accession number: MN 121709) was deposited in GenBank.
