Ammatho (Ammathella) gesar S.-Y. Huang & Volynkin in Huang et al., 2020, Zootaxa 4809 (3): 586, figs 7, 8, 19 (type locality: "2130 m, Pailong Village, Linzhi County, Linzhi Division, Xizang Autonomous Region, P. R. China").

Type material examined.

Holotype: male, altitude 2130 m, 30.VII.2017, Pailong Village, Linzhi County, Linzhi Division, Xizang Autonomous Region, P. R. China, leg. Si-yao Huang, Shu-qin Ji, Fu-hong Wei and Shi-fang Mo, preparation in glycerol by Huang (SCAU). Paratypes: 2 males, the same data as in the holotype (SCAU).

Diagnosis.

Length of forewing 11.5-14 mm. Ammathella gesar is externally very similar to A. monpa sp. nov. and A. lhoba sp. nov., and a reliable identification requires the examination of the genitalia structures. Males of A. gesar and A. lhoba sp. nov. can be distinguished from each other by the distal half of the abdomen, which has a markedly denser admixture of blackish scales in A. gesar . The male genitalia of A. gesar are most similar to those of A. monpa sp. nov., but the genital capsule differs in the longer and broader juxta without a medial process, the shorter distal costal process, and the apically pointed distal saccular process (it is distally thicker and apically rounded in A. monpa sp. nov.). Compared to A. monpa sp. nov., the phallus of A. gesar is slightly narrower, the subbasal diverticulum of the vesica is smaller and distally narrower, and the cornuti on the ventral medial diverticulum are markedly smaller.

The female is unknown.

Distribution.

Known only from the type locality in Linzhi County, southeastern Xizang, China.
