Thiotricha Meyrick, 1886 is a large and morphologically diverse genus in the subfamily Thiotrichinae of the family Gelechiidae. The distribution is mainly concentrated in the Old World, but only 14 species were previously known in China. In this study, we reviewed Chinese Thiotricha and examined related species distributed in Korea, Japan, Cambodia and Vietnam. As a result, 84 new species are described in the genus: T. apicispinea sp. nov., T. fasciaria sp. nov., T. atralata sp. nov., T. lativalva sp. nov., T. gracilis sp. nov., T. vittata sp. nov., T. minuta sp. nov., T. albida sp. nov., T. ateriguttata sp. nov., T. parvunca sp. nov., T. eborinicosta sp. nov., T. lacrimiformis sp. nov., T. umbrosidorsa sp. nov., T. asymmetricijuxta sp. nov., T. lunata sp. nov., T. spatulativalva sp. nov., T. uncaticula sp. nov., T. curtisacca sp. nov., T. candidipalpa sp. nov., T. spinesigna sp. nov., T. angusteproducta sp. nov., T. cornuata sp. nov., T. crassiflagella sp. nov., T. minorirugata sp. nov., T. tridentata sp. nov., T. digitiprojecta sp. nov., T. truncata sp. nov., T. peniticoncava sp. nov., T. brevissima sp. nov., T. confluens sp. nov., T. rosatorna sp. nov., T. cochlearis sp. nov., T. albimaculata sp. nov., T. rufimarginata sp. nov., T. deltaloba sp. nov., T. roseapicalis sp. nov., T. jianfengensis sp. nov., T. grandimacula sp. nov., T. latistriata sp. nov., T. contracta sp. nov., T. projecta sp. nov., T. duristria sp. nov., T. robustiseta sp. nov., T. setangulata sp. nov., T. macularis sp. nov., T. vittaticosta sp. nov., T. lineata sp. nov., T. albalata sp. nov., T. disciformis sp. nov., T. rhombiformis sp. nov., T. semota sp. nov., T. karsholti sp. nov., T. wufengensis sp. nov., T. angustifasciata sp. nov., T. anthracina sp. nov., T. longisigna sp. nov., T. cultriformis sp. nov., T. vivida sp. nov., T. magnalata sp. nov., T. rotundata sp. nov., T. guizhouensis sp. nov., T. bicolor sp. nov., T. simplex sp. nov., T. globularis sp. nov., T. xizangensis sp. nov., T. ferruginea sp. nov., T. rosebasis sp. nov., T. nullisigna sp. nov., T. nigrimaculata sp. nov., T. asymmetricosta sp. nov., T. aurea sp. nov., T. lata sp. nov., T. emarginata sp. nov., T. pediformis sp. nov., T. curviciliaris sp. nov., T. recticiliaris sp. nov., T. parvimaculata sp. nov., T. apicidisca sp. nov., T. villosa sp. nov., T. flaviterminata sp. nov., T. hamatisigna sp. nov., T. acicularis sp. nov., T. rosegrammica sp. nov. and T. canimaculata sp. nov. Sixteen species are reported from China for the first time: T. attenuata Omelko, 1993, T. prunifolivora Ueda & Fujiwara, 2005, T. albicephalata Walia & Wadhawan, 2005, T. rhodomicta Meyrick, 1918, T. scioplecta Meyrick, 1918, T. polyaula Meyrick, 1918, T. poecilopa (Meyrick, 1918), T. scatebrosa (Meyrick, 1918), T. clinopeda Meyrick, 1918, T. oxygramma Meyrick, 1918, T. hoplomacha Meyrick, 1908, T. embolarcha Meyrick, 1929, T. hexanesa Meyrick, 1929, T. acrantha Meyrick, 1908, T. scotaea Meyrick, 1908 and T. pyrphora Meyrick, 1918. Four new combinations are proposed: T. barathrota (Meyrick, 1918) comb. nov., T. leucochalca (Meyrick, 1918) comb. nov., T. poecilopa (Meyrick, 1918) comb. nov. and T. scatebrosa (Meyrick, 1918) comb. nov. Based on examination of the type specimens, T. synodonta Meyrick, 1936 is synonymized with T. trichoma. Also, we divide Chinese Thiotricha into four species groups, the subocellea-group, the pontifera-group, the confluens-group and the pancratiastis-group, based on the morphology and the molecular data. Eight species are grouped into another species group (the lata-group) based only on the morphological similarities, but the generic placement of this group needs to be re-evaluated since their morphological traits do not fit well into the generic concept. Fourteen species remain unplaced, and some species such as T. dissobola Meyrick, 1935 and T. pyrphora do not show the typical characteristics of Thiotricha, suggesting that further critical reassessment is also required for the species on the basis of additional morphological and molecular evidence. In this study, a total of 110 species are finally recognized as a result of a taxonomic study on Chinese Thiotricha. Photographs of adults and genitalia are provided for all studied taxa as well as related type specimens deposited in NHMUK and MGBA.
1886年的Thiotricha Meyrick是麦蛾科Thiotrichinae亚科中一个庞大且形态多样的属。其分布主要集中在旧大陆，但此前在中国仅知有14种。在本研究中，我们回顾了中国的Thiotricha，并检查了分布于韩国、日本、柬埔寨和越南的相关物种。结果，该属描述了84个新物种：尖刺Thiotricha apicispinea sp. nov.、束带Thiotricha fasciaria sp. nov.、黑翅Thiotricha atralata sp. nov.、宽瓣Thiotricha lativalva sp. nov.、纤细Thiotricha gracilis sp. nov.、条带Thiotricha vittata sp. nov.、微小Thiotricha minuta sp. nov.、白色Thiotricha albida sp. nov.、黑斑Thiotricha ateriguttata sp. nov.、小瘤Thiotricha parvunca sp. nov.、象牙脊Thiotricha eborinicosta sp. nov.、泪形Thiotricha lacrimiformis sp. nov.、暗背Thiotricha umbrosidorsa sp. nov.、不对称 juxta Thiotricha asymmetricijuxta sp. nov.、新月形Thiotricha lunata sp. nov.、匙形瓣Thiotricha spatulativalva sp. nov.、钩状小刺Thiotricha uncaticula sp. nov.、弯曲囊Thiotricha curtisacca sp. nov.、白色须Thiotricha candidipalpa sp. nov.、刺纹Thiotricha spinesigna sp. nov.、窄突Thiotricha angusteproducta sp. nov.、角状Thiotricha cornuata sp. nov.粗壮鞭Thiotricha crassiflagella sp. nov.、微皱Thiotricha minorirugata sp. nov.、三叉Thiotricha tridentata sp. nov.、指状突出Thiotricha digitiprojecta sp. nov.、截形Thiotricha truncata sp. nov.、凹陷Thiotricha peniticoncava sp. nov.、极短Thiotricha brevissima sp. nov.、汇合Thiotricha confluens sp. nov.、玫瑰形Thiotricha rosatorna sp. nov.、耳蜗形Thiotricha cochlearis sp. nov.、白斑Thiotricha albimaculata sp. nov.、红边Thiotricha rufimarginata sp. nov.、三角叶Thiotricha deltaloba sp. nov.、玫瑰尖Thiotricha roseapicalis sp. nov.、尖峰Thiotricha jianfengensis sp. nov.、大斑Thiotricha grandimacula sp. nov.、宽条纹Thiotricha latistriata sp. nov.、收缩Thiotricha contracta sp. nov.、突出Thiotricha projecta sp. nov.、硬条纹Thiotricha duristria sp. nov.、粗壮刚毛Thiotricha robustiseta sp. nov.、刚毛角状Thiotricha setangulata sp. nov.、斑点Thiotricha macularis sp. nov.、条纹脊Thiotricha vittaticosta sp. nov.、线纹Thiotricha lineata sp. nov.、白翅Thiotricha albalata sp. nov.、盘状Thiotricha disciformis sp. nov.、菱形Thiotricha rhombiformis sp. nov.、半斑Thiotricha semota sp. nov.、卡氏Thiotricha karsholti sp. nov.、五峰Thiotricha wufengensis sp. nov.、窄带Thiotricha angustifasciata sp. nov.、炭疽色Thiotricha anthracina sp. nov.、长纹Thiotricha longisigna sp. nov.、刀形Thiotricha cultriformis sp. nov.、鲜艳Thiotricha vivida sp. nov.、大斑Thiotricha magnalata sp. nov.、圆形Thiotricha rotundata sp. nov.、贵州Thiotricha guizhouensis sp. nov.、双色Thiotricha bicolor sp. nov.、简单Thiotricha simplex sp. nov.、球形Thiotricha globularis sp. nov.、西藏Thiotricha xizangensis sp. nov.、铁锈色Thiotricha ferruginea sp. nov.、玫瑰基部Thiotricha rosebasis sp. nov.、无纹Thiotricha nullisigna sp. nov.、黑斑Thiotricha nigrimaculata sp. nov.、不对称脊Thiotricha asymmetricosta sp. nov.、金色Thiotricha aurea sp. nov.、宽Thiotricha lata sp. nov.、缺刻Thiotricha emarginata sp. nov.、足形Thiotricha pediformis sp. nov.、弯睫毛Thiotricha curviciliaris sp. nov.、直睫毛Thiotricha recticiliaris sp. nov.、小斑Thiotricha parvimaculata sp. nov.、顶端盘Thiotricha apicidisca sp. nov.、具毛Thiotricha villosa sp. nov.、黄端Thiotricha flaviterminata sp. nov.、钩纹Thiotricha hamatisigna sp. nov.、针状Thiotricha acicularis sp. nov.、玫瑰纹Thiotricha rosegrammica sp. nov.和犬斑Thiotricha canimaculata sp. nov.。16个物种首次在中国被报道：渐狭Thiotricha attenuata Omelko，1993、李叶Thiotricha prunifolivora Ueda & Fujiwara，2005、白头Thiotricha albicephalata Walia & Wadhawan，2005、红杂色Thiotricha rhodomicta Meyrick，1918、暗织Thiotricha scioplecta Meyrick，1918、多室Thiotricha polyaula Meyrick，1918、杂色Thiotricha poecilopa (Meyrick，1918)、粗糙Thiotricha scatebrosa (Meyrick，1918)、斜足Thiotricha clinopeda Meyrick，1918、尖纹Thiotricha oxygramma Meyrick，1918、武装Thiotricha hoplomacha Meyrick，1908、内拱Thiotricha embolarcha Meyrick，1929、六室Thiotricha hexanesa Meyrick，1929、顶刺Thiotricha acrantha Meyrick，1908、暗区Thiotricha scotaea Meyrick，1908和红痣Thiotricha pyrphora Meyrick，1918。提出了4个新组合：网纹Thiotricha barathrota (Meyrick，1918) comb. nov.、白铜色Thiotricha leucochalca (Meyrick，1918) comb. nov.、杂色Thiotricha poecilopa (Meyrick，1918) comb. nov.和粗糙Thiotricha scatebrosa (Meyrick，1918) comb. nov.。基于模式标本的检查，1936年的Synodonta Thiotricha Meyrick被同义化为trichoma Thiotricha。此外，我们根据形态学和分子数据将中国的Thiotricha分为4个物种组，即亚单眼组、pontifera组、汇合组和pancratiastis组。8个物种仅根据形态相似性被归为另一个物种组（宽组），但由于它们的形态特征与属的概念不太相符，该组的属级地位需要重新评估。14个物种仍未归类，一些物种如1935年的dissobola Thiotricha Meyrick和pyrphora Thiotricha不显示Thiotricha的典型特征，这表明还需要根据更多的形态学和分子证据对这些物种进行进一步的严格重新评估。在本研究中，对中国Thiotricha的分类学研究最终共确认了110个物种。为所有研究的分类单元以及保存在英国自然历史博物馆（NHMUK）和日本国立自然科学博物馆（MGBA）的相关模式标本提供了成虫和生殖器的照片。
