Thiotricha hoplomacha Meyrick, 1908

( Figs 1C , 21D , 27R , 45B , 66G, H , 73C )

Thiotricha hoplomacha Meyrick, 1908: 441 ; 1925: 102; Gaede, 1937: 305; Clarke, 1969: 460; Ivinskis et al., 1984: 39. TL: Assam, India. TD: NHMUK.

Type material ( Figs 66G, H , 73C ). Holotype ♂, INDIA, Assam, Khasi Hills , ix.1906, genitalia slide no. J. F.G.C. 8331 ( NHMUK).

Additional material examined. CHINA: Xizang Autonomous Region: 2 ♂♂, 80 K (29.66°N, 95.49°E), 2076 m, Motuo County, 8.viii.2018, leg. Mujie Qi, genitalia slide nos. LGE18611, LGE18612 .

Diagnosis. Adult ( Figs 1C , 21D ). Wingspan 14.0− 17.5 mm. It is a large and slender moth with round forewing apex. The wing markings are unique in the genus as three transverse streaks are obliquely running from dorsum toward costa. The male genitalia ( Fig. 45B ) are differentiated from its allies by the large ovate anellus lobe bearing a spine-like apical bristle.

Variations. The oblique streak near the forewing base is short and almost reached the fold in the holotype whereas the streak is much longer and meets the costal band in two males from China. Also , the Chinese specimens have the forewing apex tinged with rosy pink. In the male genitalia, the aedeagi of Chinese specimens have the ventral surface projected at distal 1/3, but the projection is invisible in the holotype. It is possibly due to the different direction when mounted, but additional specimens need to be examined to confirm the variation of the shape of aedeagus .

Distribution. China (Xizang), India.

Remarks. This species is recorded from China for the first time.
