(Figs 1, 2, 7)
Type Material. Holotype: ♂, China, Hubei Province, Shennongjia, Songbai town, 31°44’21.30” N 110°41’15.62” E, 08–VIII– 2018, 900 m, Tiantian Yu leg. (SCAU).
Description. Holotype (Figs 1, 2). Alar expanse 25 mm; body length 14 mm; forewing 13 mm; antenna 6 mm.
Head: antenna black with violet sheen; frons and vertex black, with dark brown sheen; basal segment of labial palpus pale yellow to white, mid segment white, apical segment white and mixed with a few pale yellow scales apically; proboscis small; eyes with a row of white scales anteriorly; pericephalic scales pale yellow to white dorsally and white laterally.
Thorax: patagia and tegula black with bronze sheen; metathorax submedially with two small yellow spots posteriorly. Forewing brownish black with purple sheen; ETA semi-transparent with bluish sheen; outer margin and cilia brownish black with dark brown sheen. Hindwing covered with yellowish semi-transparent scales, with bluish sheen; veins brownish black; discal spot not developed; outer margin and cilia brownish black with bronze sheen; vein 1A well-developed. Legs with fore femur dorsally brownish black with dark brown sheen, ventrally covered with yellow scales with a few white scales basally; fore tibia mixed with dark yellow hairs both dorsally and ventrally; fore tarsus dark brown, with admixture dark yellow scales ventrally; mid and hind femora brownish black with bronze sheen, interiorly covered with yellowish white scales; mid tibia cream white ventrally; mid tarsus yellowish white interiorly, dorsally mixed with a few dark yellow scales; hind tibia yellowish white interiorly, with yellowish white tuft dorsal-distally; spurs dorsally dark brown, ventrally yellowish white; hind tarsus brownish black dorsally and mixed with a few dark yellow scales, yellowish white both ventrally and interiorly, with bronze sheen.
Abdomen: black with dark brown sheen; tergite 2 with a broad yellow band posteriorly; tergite 3 with a narrow yellow stripe at posterior margin; tergites 4 yellow in posterior half; tergites 5 and 6 yellow in posterior two thirds; tergite 7 black, dorsally mixed with a few yellow scales; sternites 2 and 3 each with a yellow stripe posteriorly; sternites 4 and 5 with broad yellow bands and with white posterior margins; anal tuft small, black.
Male genitalia (Fig. 7). Uncus slightly bent, finger shaped, with a pointed and strongly sclerotized apex; tegumen slender; valva ovoid, covered with short hair-like setae in distal half; saccus broad, triangular; phallus relatively broad, with a blunt process apically; coecum penis narrow; vesica with numerous spine-like cornuti.
Female unknown.
Diagnosis. Externally, this new species is close to P. pieli. However, based on the detailed description by Lieu (1935) it can be distinguished by the coloration of the labial palpus (basal segment pale yellow to white, mid and apical segments covered with white scales in P. kishidai sp. nov., with white hairs at the base and covered with yellow scales towards the apical segments in while in P. pieli), the patagia (entirely black with dark brown sheen in P. kishidai sp. nov., with a pair of yellow spot posterior-laterally in P. pieli), the metathorax (black with two yellow spots submedial-posteriorly in P. kishidai sp. nov., dark brown without yellow spots in P. pieli), the details of the abdomen (tergite 1 entirely black, tergite 3 with a narrow yellow stripe, tergite 6 yellow in posterior two thirds; sternites 4 and 5 with broad yellow bands in P. kishidai sp. nov., tergite 1 yellow laterally, tergites 3 and 6 entirely dark brown and sternites 4 and 5 with narrow yellow bands in P. pieli). The male genitalia of these two species are similar but the phallus is somewhat broader and the vesica with numerous, larger spine-like cornuti in P. kishidai sp. nov. (see Figs 7b, 16, 17 in Lieu, 1935). P. kishidai sp. nov. also resembles to P. gravis, however, it differs by the smaller size (alar expanse 25 mm in P. kishidai sp. nov., more than 35 mm in P. gravis), the coloration of the pericephalic scales (pale yellow dorsally and white laterally in P. kishidai sp. nov., entirely white in P. gravis), the patagia (entirely black in P. kishidai sp. nov., black with a pair of large yellow spots posterior-laterally in P. gravis), the metathorax (with two yellow spots submedial-posteriorly in P. kishidai sp. nov., black without yellow spots in P. pieli), as well as the abdomen (tergite 1 black, tergites 4 and 6 with yellow posterior bands, sternite 4 with a broad yellow band in P. kishidai sp. nov., tergite 1 yellow laterally, tergites 4 and 6 black, sternite 4 black in P. gravis).
Distribution. Paradoxecia kishidai sp. nov. is only known from the type locality in Shennongjia, Hubei.
Remark. The holotype was collected at edge of the farmland which is surrounded by several low hills. It was attracted to artificial pheromone lures in the noon. The pheromone lures were produced by Pherobank Company (Wijk bij Duurstede, the Netherlands).
Etymology. This beautiful species is dedicated to Mr. Yasunori Kishida of Tokyo, who has made important contributions to the taxonomy of the Lepidoptera of Japan and south-east Asia.
Molecular data. The barcode of Paradoxecia kishidai sp. nov. (658 bp fragment of COI; accession number: MN 121708) was deposited in GenBank.
