F3B4DBC7943850BCB0DD53F105DA7CCF.taxon	diagnosis	Diagnosis. The forewing is white with broad, dark brown fascia, a rather large yellow patch before the apex, and a black rounded apical spot demarcated by a white line. The anellus lobe of the male genitalia is a short and heavily sclerotized beak-shaped lobe basally, armed with a small claw-like process apically, which is a unique characteristic of this species. The apopyhsis posterioris of the female genitalia is ca. 1 / 2 the length of the papilla analis and approx. two times longer than the apophysis anterioris; the signum is absent in the corpus bursae.	en	Kyaw, Khine Mon Mon, Yagi, Sadahisa, Oku, Jouhei, Sakamaki, Yositaka, Hirowatari, Toshiya (2019): Taxonomic study of Thiotricha Meyrick (Lepidoptera, Gelechiidae) in Japan, with the description of two new species.

A1D2408ECD4B5B80B43012FE5C330042.taxon	diagnosis	Diagnosis. This species is similar to T. biformis, which is known in the Russian Far East and Japan but can be distinguished by markings in the distal yellow zone of the forewing with a distinct black streak below the middle of the yellow zone. The male genitalia is similar to those of T. epiclista Meyrick, 1908 described from Khasi Hills, India, but can be distinguished by the basally broadened valva and the presence of a thumb-like basal process bearing numerous setae, the lack of a pre-apical spine on the costal process of the valva, and the slender posterior part of the phallus.	en	Kyaw, Khine Mon Mon, Yagi, Sadahisa, Oku, Jouhei, Sakamaki, Yositaka, Hirowatari, Toshiya (2019): Taxonomic study of Thiotricha Meyrick (Lepidoptera, Gelechiidae) in Japan, with the description of two new species.

A1D2408ECD4B5B80B43012FE5C330042.taxon	biology_ecology	Biology (Fig. 11). Although the host plant of T. chujaensis is unknown, we found that some specimens of this species preserved in OPU were labeled as having been reared on Mallotus japonica (Euphorbiaceae). In the present study, we confirmed that the larvae feed on this plant in the field. The larvae also make portable cases with flower buds or attack the leaf bud (young shoot) of the host plant. The larva uses the flower buds at flowering time to make a case from the plant. After making the portable case, the larva moves from one place to another and attaches the case to the lower surface of the leaf for pupation (Fig. 11 C). When there is an early leaf bud (young shoot) on the host plant, the larva penetrates the petiole of the young, newly emerged leaf and feeds inside (Fig. 11 E-G). There is no external injury during the feeding period until the leaf is fully grown. Before pupation, the larva cuts the petiole and makes a portable case. After that, it fixes the portable case sideways. Pupation also takes place inside the cases and pupal exuvia is left after the adult emerges.	en	Kyaw, Khine Mon Mon, Yagi, Sadahisa, Oku, Jouhei, Sakamaki, Yositaka, Hirowatari, Toshiya (2019): Taxonomic study of Thiotricha Meyrick (Lepidoptera, Gelechiidae) in Japan, with the description of two new species.

C33C34F7B36855CA93AB379B67EF3C27.taxon	diagnosis	Diagnosis. The forewing is white with a small orange patch and a black rounded spot apically. The anellus lobe of the male genitalia is narrow, slender, and longer than the valva, with a sharp and thorn-like spine at the apex, which is a unique characteristic of this species. The apopyhsis posterioris of the female genitalia is ca. 1 / 3 of the length of papilla analis and approx. half the length of the apophysis anterioris; the signum is absent in the corpus bursae.	en	Kyaw, Khine Mon Mon, Yagi, Sadahisa, Oku, Jouhei, Sakamaki, Yositaka, Hirowatari, Toshiya (2019): Taxonomic study of Thiotricha Meyrick (Lepidoptera, Gelechiidae) in Japan, with the description of two new species.

Kogi (2004) reported that adults of this species fly in July in Hokkaido and larvae live in portable cases in summer until the following spring. In late fall, the larvae move to the underside of twigs of the host plant for hibernation. The next spring, the larvae create triangular cases like hats with fragments of host plant leaves and skeletonize the leaves.	en	Kyaw, Khine Mon Mon, Yagi, Sadahisa, Oku, Jouhei, Sakamaki, Yositaka, Hirowatari, Toshiya (2019): Taxonomic study of Thiotricha Meyrick (Lepidoptera, Gelechiidae) in Japan, with the description of two new species.

EB01F302B41C555194E3114082D4FF0F.taxon	diagnosis	Diagnosis. At a glance, the external features are similar to those of T. chujaensis (Park, 2016) comb. nov. but it can be distinguished by wing markings in the distal yellow zone of the forewing, which lacks a distinct blackish streak below the middle of the yellow zone and features grayish scales at the costal margin before the apex and the area beyond the tornus. Additionally, it can easily be distinguished based on the male genitalia; the uncus is more rounded apically; the gnathos is U-shaped and acute apically; the valva is narrowly elongate with a sharped pre-apical process ca. 1 / 4 of the way along its length and the vinculum lacks thumb-like lobes posteriorly; the saccus has a rounded base. The shape of the phallus is also different. However, the male genitalia are similar to those of Thiotricha clidias Meyrick, 1918, which was described from Khasi Hills, India, although they differ in the shape of the phallus. In T. clidias Meyrick, 1918, the phallus is rounded basally, abruptly sinuate and slender in distally but as a cucurbit-shaped in T. elaeocarpiella sp. nov.	en	Kyaw, Khine Mon Mon, Yagi, Sadahisa, Oku, Jouhei, Sakamaki, Yositaka, Hirowatari, Toshiya (2019): Taxonomic study of Thiotricha Meyrick (Lepidoptera, Gelechiidae) in Japan, with the description of two new species.

EB01F302B41C555194E3114082D4FF0F.taxon	biology_ecology	Biology (Fig. 12). The larva uses the flower bud or the young shoot of its host plant to construct portable cases. When it utilizes a flower bud, at first, the larva penetrates the bud and then lives and feeds within it. After that, it moves from one flower to another by carrying the bud and attaching it to other flower buds to complete its life cycle (Fig. 12 D, E). When the larva is ready to pupate, it attaches the case to the underside of a leaf with silk. When it utilizes a young shoot (Fig. 12 C), the larva leaves small dot-like traces of feeding after making cases by the shoot. Pupation also takes place inside the portable cases. After completing development, the adult emerges from the case, leaving the pupal exuvia inside.	en	Kyaw, Khine Mon Mon, Yagi, Sadahisa, Oku, Jouhei, Sakamaki, Yositaka, Hirowatari, Toshiya (2019): Taxonomic study of Thiotricha Meyrick (Lepidoptera, Gelechiidae) in Japan, with the description of two new species.

The external morphological character of this new species is quite similar to that of T. angustella; the wings of both species are shaded brown apically. However, the two can be differentiated based on the brightness of the color of the apical wing markings. In the new species, the wings feature a huge dark brown area distally, so it can be recognized easily at a glance. Likewise, in the male genitalia, the anellus lobe is a small membranous spherical lobe basally with a delicate, thread-like spine apically. Also, the size of apophyses and shape of the signum in the female genitalia are different to those of T. angustella. On the other hand, the male genitalia are quite similar to those of Thiotricha xanthodora Meyrick, 1923, which was described from Pyinmana, Myanmar, but differ in terms of the uniformly elongate valva, spherical-shaped and straight phallus. In T. xanthodora, the shape of the valva is dilated along 1 / 3 of its length apically whereas the phallus is slightly rounded basally and twisted forward.	en	Kyaw, Khine Mon Mon, Yagi, Sadahisa, Oku, Jouhei, Sakamaki, Yositaka, Hirowatari, Toshiya (2019): Taxonomic study of Thiotricha Meyrick (Lepidoptera, Gelechiidae) in Japan, with the description of two new species.
