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-40157 (TAAHU). Paratypes: 5 males, 3 females, same data as the holotype, slides STS-40148, STS-40154, STS-40155 & STS-40163 (male); STS-40156, STS-40162 & STS-40164 (female) (TAAHU).
Diagnosis.
Length of forewing 11.4-11.9 mm (n = 5, 11.5 mm in holotype) in males and 12.6-13.1 mm (n = 3) in females. Ammathella longicornuta sp. nov. is externally reminiscent of 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. garo (Figs 13 View Figure 11–18 , 14 View Figure 11–18 , 27 View Figure 27–30 , 33 View Figure. 31–35 ) but is distinguished by the male tip of abdomen, which is pinkish and covered with much lesser blackish hair-like scales than in the similar congeners, and the obsolete submarginal dull yellowish spots on the forewing (whereas they are prominent in A. gesar and A. garo ). In the male genitalia, A. longicornuta sp. nov. is distinguished from the two similar congeners by the combination of the following characters. (1) The juxta lacks a medial process, similar to A. gesar , while the juxta of A. garo bears a long conical process. (2) The medial costal process is minute while it is large and prominent in A. gesar and A. garo . (3) The distal costal process is situated more distally than in A. gesar and A. garo , and is much broader and shorter, whereas it is lobe-like and markedly narrower in the congeners. (4) The distal saccular process is directed distally whereas it is up curved in A. gesar and A. garo . (5) In the phallus vesica, the subbasal diverticulum bears a small cluster of cornuti apically (absent in A. gesar and A. garo ). (6) The semiglobular medial diverticulum bears a broad cluster consisting of several large and long cornuti basally and numerous smaller cornuti ventro-distally, while in A. gesar and A. garo , the cornuti in the semiglobular medial diverticulum are more or less equal in size. (7) The ventro-basal elongate diverticulum of A. longicornuta sp. nov. is longer than in A. garo , while it is absent in A. gesar . Since the female of A. gesar is unknown, the female genitalia of A. longicornuta sp. nov. are compared only to A. garo , from which the new species differs in the shorter and broader ductus bursae, and the lack of a signum bursae, which is present in A. garo .
Etymology.
The specific epithet Ammathella longicornuta refers to the presence of long and large cornuti on the surface of the semiglobular medial diverticulum in vesica of male genitalia.
Distribution.
Currently known only from the type locality in Motuo County, southeastern Xizang, China.
