The genus Duda comprises 61 described species classified into four species groups: , , and . This genus is distributed exclusively in the Old World, and is rich in species in the tropical and subtropical areas of the Oriental, Australasian, and Afrotropical regions. In this paper, a new species group, the group, is established for six new species discovered from the Oriental region. The delimitation of these species is firstly performed in light of morphology and further with the aid of DNA sequences of the mitochondrial and (cytochrome oxydase, subunits I and II, respectively) genes, considering also their respective geographical origins. Then, the new species ( Yang & Gao, , Yang & Gao, , Yang & Gao, , Yang & Gao, , Yang & Gao, , and Yang & Gao, ) are described, and a key, based on not only morphological but also molecular information, is provided.
杜达属包含61个已描述的物种，分为四个物种组： 、 、 和 。该属仅分布于东半球，在东洋界、澳大拉西亚和热带非洲地区的热带和亚热带地区物种丰富。在本文中，基于从东洋界发现的六个新物种建立了一个新的物种组，即 组。这些物种的界定首先根据形态学进行，然后借助线粒体 和 （分别为细胞色素氧化酶亚基I和II）基因的DNA序列，并考虑它们各自的地理起源。然后，描述了新物种（杨 & 高， ，杨 & 高， ，杨 & 高， ，杨 & 高， ，杨 & 高， ，以及杨 & 高， ），并提供了一个不仅基于形态学而且基于分子信息的检索表。
