摘要
The eastern part of the southern macroslope of the Himalayan Range, Hengduan Mountains and the complex of smaller ranges from Hengduan southward to northern Indochina is one of the taxonomic hotspots of Calypogeia in Asia and the world. Two main circumstances hamper the understanding of taxonomic diversity of the genus in this area: the absence of recent and detailed descriptions and identification keys and the necessity of studying fresh material with surviving oil bodies in leaf cells. This study resulted in 1) eleven species confirmed for this vast land, 2) seven more taxa recorded but likely based on identification mistakes and 3) fourteen more taxa that are not yet recorded but may be expected in the area. All these taxa are discussed, and most of them are illustrated and described based on the types; an identification key is provided. The occurrence of North Holarctic taxa is hardly probable in the Sino-Himalaya, whereas new records of taxa known from the southern half of the Japanese Archipelago, Taiwan and southeastern mainland China are possible.

横断山脉喜马拉雅山脉南部大斜坡的东部，以及从横断山脉向南至印度支那北部的较小山脉，是亚洲乃至世界上的花萼地理分类热点之一。有两个主要的情况妨碍了对该领域属分类学多样性的理解：缺乏最新和详细的描述和鉴定关键，以及研究叶细胞中尚存油体的新鲜物质的必要性。这项研究的结果是：1）在这片广阔的土地上确认了11个物种； 2）记录了7个分类单元，但很可能是基于识别错误； 3）尚未记录但可能在该地区被分类的14个分类单元。讨论了所有这些分类单元，并根据类型对其中的大多数进行了说明和描述。提供了一个识别码。在中喜马拉雅山极不可能出现北北冰洋类群，而从日本群岛南半部，台湾和中国大陆东南部已知的新的类群记录是可能的。
