Huang, Si-Yao, Zhu, Li-Juan, Chen, En-Yong, Xu, Yong-Qiang, Wang, Min, Fan, Xiao-Ling, Pan, Zhao-Hui & Espeland, Marianne, 2022, Contribution to the knowledge of the genus Agalope Walker from mainland China with descriptions of four new species (Lepidoptera, Zygaenidae, Chalcosiinae), Zootaxa 5165 (4), pp. 557-574 : 562-565

Agalope chayuensis S.-Y. Huang & Pan sp. n.

( Figs 5–7 , 34–36 )

Type material. Holotype: male, 1.VIII.2017, Longgu Village , Chayu County, Linzhi City , Xizang Autonomous Region, P. R. China, leg. Jing-kuo Hu, slide STS-34878 ( TAAHU) . Paratypes: 2 males, same data as the holotype, slides STS-34879 & STS-34880 ( TAAHU) .

Diagnosis. Length forewing 24.4–27.3 mm in male (27.3 mm in holotype). Agalope chayuensis sp. n. is reminiscent of A. pica ( Figs 8–10 , 37, 38 ) from Taiwan, but it can be easily distinguished from the latter by the combination of the following characters: 1) size larger, length of forewing 24.4–27.3 mm against 20.4–23.3 mm in A. pica ; 2) apex of forewing is somewhat protruding outwards, while in A. pica it is more rounded; 3) darkish pattern on forewing is pale blackish brown, less contrasting with the pale ground color, while in A. pica the darkish pattern is deeper and more contrasting; 4) antemedial band on forewing is more regular and intact, while that in A. pica is irregular and often broken; 5) uncus is slightly broader; 6) branches of the basal part of the uncus is shorter (indicated by arrow in both species in Figs. 34–38 ). Agalope chayuensis sp. n. is also similar to A. aurelia ( Figs 16–20 , 43, 44 , 49, 50 , 60 ) from Western Yunnan, China and A. owadai sp. n. ( Figs 11–15 , 39–42 , 45–48 , 59 ) from Bomi and Jiali Counties, Xizang, China described below by sharing similar forewing shape and transverse bands on forewing upperside, but it can be easily distinguished from both species by the shape of the juxta, which is smooth, spade-like and not bifurcate, similar to that of A. pica , while in A. aurelia and A. owadai sp. n. it is clearly bifurcate apically and each lobe is covered by spinules.

Female unknown.

Distribution. Known from Chayu County ( Fig. 66 ) in SE Xizang, P. R. China.

Etymology. The specific epithet chayuensis is derived from the type locality, Chayu County.
