Treatment

Ammathella monpa S.-Y. Huang, Yin & Volynkin sp. nov.

Figs 8-10 View Figure 1–10 , 23 View Figure 23–26 , 24 View Figure 23–26

Type material.

Holotype: male, altitude 800 m, 9.VI.2017, Beibeng Village, Motuo County, Linzhi City, Xizang Autonomous Region, China, Zhao-hui Pan leg., slide STS-40151 (TAAHU). Paratypes: 3 males, the same data as in the holotype, slides STS-40159, STS-40167 & STS-40169 (TAAHU).

Diagnosis.

Length of forewing 10.6-11.8 mm (n = 4, 10.6 mm in holotype). Ammathella monpa sp. nov. is externally very similar to A. gesar (Figs 11 View Figure 11–18 , 12 View Figure 11–18 , 25 View Figure 23–26 , 26 View Figure 23–26 ) and a reliable identification requires the examination of the genitalia structures. Compared to another similar species, A. garo (Figs 13 View Figure 11–18 , 14 View Figure 11–18 , 27 View Figure 27–30 , 33 View Figure. 31–35 ), the new species has hindwing cilia black from apex to vein CuA2, while it is pinkish, scattered with black, from apex to tornus in A. garo . In the male genitalia, A. monpa sp. nov. is distinguished from the two similar congeners by the combination of the following characters. (1) The juxta is much narrower and smaller. (2) The medial process of juxta is short, round, and covered with spinules thoroughly, whereas the juxta of A. garo bears a long conical medial process, and that of A. gesar lacks a process. (3) The distal costal process is situated more distally from the medial costal process, similar to that in A. garo , while it is situated closer to the medial costal process in A. gesar . (4) The distal costal process is longer than in A. gesar and A. garo . (5) The distal saccular process is apically rounded, similar to A. garo , while it is apically pointed in A. gesar . (6) The phallus is slender and straight, similar to A. gesar , while forms an S-like curve in A. garo . (7) In the phallus vesica of A. monpa sp. nov., the subbasal diverticulum is larger than in A. gesar and A. garo . Additionally, the cornuti on the ventral medial diverticulum of the new species are larger than in A. gesar and more similar to those in A. garo .
