The holotypeof  T. tylephorahas a creamy forewing sprinkled with fuscous scales and marked with longitudinal streaks in the distal 1/3, but there is a great variation in the forewing pattern in other specimens examined. The male genitalia ( Fig. 39A) are diagnosed by the narrow valva, the large ovate anellus lobe bearing a robust apical bristle and the long aedeagus strongly narrowed distally. In the female genitalia ( Fig. 55C), the strongly produced posterior margin of tergum VIII and the presence of a long and linear sclerite at the base of ductus bursae are diagnostic.   Distribution. China( Henan, Hubei, Hunan, Shaanxi, Sichuan, Tianjin, Zhejiang) (Li & Wang 2009), Korea, Japan.   Remarks.In the Chinese specimens, the wing pattern of  T. tylephorais extremely variable ( Fig. 14): some have a large patch at the base of dorsum; some have longitudinal streaks from base to near apex or only in distal half; or the markings are all indistinct. Among them, the individuals with a trapezoidal patch are closely related to  T. trapezoidella( Caradja, 1920)described from Far East Russia. The male genitalia are unknown for  T. trapezoidella, but the female genitalia of the lectotypehave been illustrated in previous studies ( Park 1998; Park & Ponomarenko 2007). Based on that, there is no difference distinguishing  T. trapezoidellafrom  T. tylephoraexcept the size of corpus bursae, which can be variable within a species of  Thiotricha. Considering that the male genitalia of the specimens with the trapezoidal patch are nearly identical to those of the holotypeof  T. tylephora, it is possible that  T. tylephorais a junior synonym of  T. trapezoidella. However, further examination will be required using both molecular and morphological evidence since a high degree of intraspecific variability in the COI gene has been detected among  T. tylephoraspecimens (LGE personal observation, unpublished data). We identify the Chinese  T. tylephorabased on examination of specimens collected from the type locality (Mt. Tianmu of Zhejiang Province) and their similarity in male genitalia. Some specimens from the Hubei Province are genetically grouped with the materials from Mt. Tianmu and these were also included in this study. 1932-11 NHMUK Hermann Hone & J.F.G.
