Species of Devadatta from Borneo are studied using both morphological and molecular methods. As well as D. podolestoides Laidlaw, four new species are recognised from the island: D. aran spec. nov. (holotype ♂, from Pulong Tau National Park, Miri division, Sarawak, Malaysia, deposited in RMNH), D. clavicauda spec. nov. (holotype ♂, from Bukit Mina, Bukit Mina Wildlife Corridor, Sarawak Planted Forest Project, Bintulu division, Sarawak, Malaysia, deposited in RMNH), D. somoh spec. nov. (holotype ♂, from the Sungai Kahei area, Ulu Balui, Kapit division, Sarawak, Malaysia, deposited in RMNH) and D. tanduk spec. nov. (holotype ♂, from Poring Hot Springs, Kinabalu National Park, West Coast division, Sabah, Malaysia, deposited in RMNH). The Philippine taxon D. basilanensis Laidlaw is considered a good species rather than a subspecies of D. podolestoides. The Bornean species plus D. basilanensis are provisionally considered to form a species group, the podolestoides-group, within Devadatta. The species of the podolestoides-group are so similar in morphology and colouration that they are close to truly cryptic species. Two species appear to exhibit character displacement where their ranges overlap with other Devadatta species. A molecular analysis using four markers (COI, 16S, ITS and 28S) is presented. This analysis includes specimens of all species from the podolestoides-group and two Devadatta species from mainland Asia.
我们运用形态学和分子方法对婆罗洲的德瓦达塔种类进行了研究。除了波多莱斯特德瓦达塔（Devadatta podolestoides Laidlaw）之外，我们还从该岛屿识别出了四个新物种：阿兰德瓦达塔（D. aran spec. nov.）（正模♂，采自马来西亚砂拉越米里区普隆陶国家公园，存于荷兰国家自然历史博物馆）、棒尾德瓦达塔（D. clavicauda spec. nov.）（正模♂，采自马来西亚砂拉越民都鲁区砂拉越种植林项目布基米纳野生动物走廊的布基米纳，存于荷兰国家自然历史博物馆）、索莫德瓦达塔（D. somoh spec. nov.）（正模♂，采自马来西亚砂拉越加帛区乌鲁巴鲁的双溪卡黑地区，存于荷兰国家自然历史博物馆）和丹杜克德瓦达塔（D. tanduk spec. nov.）（正模♂，采自马来西亚沙巴西海岸区基纳巴卢国家公园的波令温泉，存于荷兰国家自然历史博物馆）。菲律宾分类单元巴锡兰德瓦达塔（D. basilanensis Laidlaw）被视为一个独立的物种，而非波多莱斯特德瓦达塔的亚种。婆罗洲的这些物种加上巴锡兰德瓦达塔暂时被认为在德瓦达塔属内构成一个物种组，即波多莱斯特物种组。波多莱斯特物种组的物种在形态和颜色上非常相似，几乎可称为真正的隐存种。有两个物种在其分布范围与其他德瓦达塔物种重叠的地方似乎表现出特征取代现象。我们展示了一项使用四个标记（COI、16S、ITS和28S）的分子分析。该分析涵盖了波多莱斯特物种组所有物种的标本以及来自亚洲大陆的两个德瓦达塔物种。
