Forewing transparent brownish, with a bronze blue sheen; costal and anal margins black; R4 and R5 long stalked; discal spot cuneiform, relatively broad; veins dark brownish black; distal position of PTA and the cell between veins Cu1 and Cu2 basally scattered with dark brown scales; outer margin narrow; cilia dark brown. Hindwing transparent brownish; discal spot black and broad; anal area transparent without brownish tint; veins black; outer margin narrow; cilia dark brown.  Abdomen: black; tergites 2–4 with blue tint; tergite 5 red-orange, with black stripes anteriorly, tergites 6–7 covered with red-orange scales; sternite 2 black; sternites 3–5 with a red-orange spot medially; sternite 5 mixed with a few bright orange scales, and with red-orange scales laterally; sternite 7 orange; anal tuft orange.  Male genitalia. ( Fig. 9). Uncus slender, curved medially, slightly narrow and up-turned distally; tegumen narrow; gnathos narrow, apically flat; tuba analis with subscaphium distinctly sclerotized; valva triangular-oval, narrow and rounded apically, dorsal half of ventral side densely covered with hand-shaped setae, ventral half of ventral side covered with long simple setae; crista sacculi covered with short, strongly sclerotized setae; saccus short finger-shaped, basally blunt; phallus simple, with a sclerotized plate apically; vesica with numerous, small spicules.   Diagnosis.This new species is superficially similar to  Taikona polevoyi Gorbunov, 2018. However,  Taikona gaoligongshana  sp. nov.can be easily separated by its somewhat smaller size (alar expanse 29–35 mmin  T. gaoligongshana  sp. nov., alar expanse 31.8–36 mmin  T. polevoyi), wing features (wings transparent brownish, discal spots of fore and hind wing distinctly broader in  T. gaoligongshana  sp. nov.while wings transparent pale yellowish in  T. polevoyi). In addition, the male genitalia of new species differ from  T. polevoyi(relatively broad valva, the dorsal half of the ventral surface densely covered with hand-shaped setae; saccus broader, basally blunt; gnathos narrow, without dentate process). There are no similar Paranthreninispecies known from China( Kallies et al. 2014)  Individual variability.The paratypespecimen displays variation in the coloration of the abdomen: male with tergites 5–6 black; tergite 6 with a narrow red-orange stripe posteriorly; sternite 5 almost covered with red-orange scales.   Distribution. China( Yunnan Province, XizangAutonomous Region).   Etymology.The scientific name is derived from Gaoligongshan, the typelocality.  Molecular data.The new barcode sequence of  Taikona gaoligongshanaYu, Arita & Kallies,  sp. nov.(658 bp fragment of COI) was deposited in GenBank (accession number: PP436719.1) 4847517307 2023-07-25 KIZ Tiantian Yu & No. China Gongshan County 1500 27.89611 Nujiang Lisu Autonomous Prefecture 20 98.66473 1 136 KIZ 0135567 1 1 Yunnan holotype 4847517306 2023-07-25 KIZ Tiantian Yu & No. China Gongshan County 1500 27.89611 Nujiang Lisu Autonomous Prefecture 20 98.66473 1 136 KIZ 0135568 1 1 Yunnan paratype 4847517303 2017-07-25 SCAU Tiantian Yu China Motuo County Beibeng Village Autonomous Region 1 136 1 1 Xizang paratype
