During several excursions to the Chin Hills of Myanmar from 2001 to 2015, rich collections of caddisflies were made which form the basis of the present taxonomic and biogeographic study. A total of 106 species were identified including seven new species. They are described as Arctopsyche subflavasp. nov., Hydromanicus abdominalissp. nov., Cheumatopsyche janosolahisp. nov., Lepidostoma subpanaitossp. nov., Aplatyphylax pumilussp. nov., Adicella natmataungensissp. nov. and Triaenodes mindatensissp. nov. Illustrations of the male genitalia and images of the adults are provided. Two species names were recognised as junior synonyms: Hydropsyche athamas Malicky & Chantaramongkol, 2000, = Hydropsyche januha Oláh & Barnard, 2008, syn. nov.; Hydropsyche khasigiri Oláh & Barnard, 2008, = Hydropsyche kiogupa Oláh & Schefter, 2008, syn. nov. In an attempt to determine the biogeographic character of the fauna, the known ranges of all resident species were plotted into three longitudinal transects from 85°–95°E, 95–98°E and 98°–108°E, ranging from the eastern Himalayas to northern Vietnam. About half of the species have ranges extending over all three transects. The fauna is equally composed of western and eastern species qualifying the Chin Hills as part of a transition zone including palearctic elements. Most of the species, which are widely distributed in south-east Asia, are members of the suborder Annulipalpia. The investigations of the authors yielded 77 autochthonous species, which have been unrecorded from the country including the newly-described taxa. This brings the number of species records from Mynamar to 304.

纳塔姆·东国家公园和缅甸钦山（Insecta，Trichoptera）邻近地区的虫的记录和描述

在2001年至2015年的几次对缅甸钦山的短途旅行中，收集了大量的地衣目，这是当前分类学和生物地理学研究的基础。总共鉴定出106种，其中包括7种新种。它们被描述为Arctopsyche subflavasp。十一月，腹部腹水。十一月，Cheumatopsyche janosolahisp。十一月，Lepidostoma subpanaitossp。11月，Aplatyphylax pumilussp。11月，Adicella natmataungensissp.。十一月 和Triaenodes mindatensissp。十一月 提供了男性生殖器的插图和成年人的图像。有两个物种名称被识别为初级同义词：Hydropsyche athamas Malicky和Chantaramongkol，2000，= Hydropsyche januhaOláh＆Barnard，2008，Syn。十一月 Hydropsyche khasigiriOláh＆Barnard，2008，= Hydropsyche kiogupaOláh＆Schefter，2008，Syn。十一月 为了确定动物群的生物地理特征，将所有定居物种的已知范围绘制成三个纵向样带，范围从东经85°-95°E，95-98°E和95-98°E和98°-108°E。喜马拉雅山至越南北部。大约一半的物种的范围延伸到所有三个样带。该动物区系由西部和东部物种组成，这些物种使Chin Hills成为包括古北极元素的过渡带的一部分。大部分物种在东南亚广泛分布，是亚唇形目亚纲的成员。作者的调查产生了77种自生物种，包括新近描述的分类群在内的该国尚未记录。这使Mynamar的物种记录数量达到304。
