摘要狐蝠属Dyacopterus Andersen，1912，包括几个中型果蝠种特有的森林地区的Sundaland和菲律宾。Dyacopterus的标本在世界博物馆的收藏中稀少，这阻碍了该属内物种界限的解决。基于我们的研究，最可用的博物馆材料，我们审查的亚属分类Dyacopterus使用颅骨测量和其他比较。在过去，2种已被描述-D。spadiceus（托马斯，1890），描述于婆罗洲，后来记录于马来半岛，和D.布鲁克西托马斯，1920年，描述于苏门答腊。这2个命名分类群通常被认为是代表这些各自种群的种或同种亚种。相反，我们的研究表明，这两种先前描述的Dyacopterus物种共同出现在巽他大陆架上。spadiceus分布于马来西亚半岛、苏门答腊岛和婆罗洲;在苏门答腊和婆罗洲的布鲁克西。我们进一步确定标本的Dyacopterus从吕宋岛和棉兰老岛在菲律宾作为一个独特的新物种，Dyacopterus rickarti的代表。这一新种不同于Sundaic类群在其更大的规模，独特的腭脊公式，并在定性颅齿特征。每个物种的自然历史，就目前所知，简要回顾。
Abstract The pteropodid genus Dyacopterus Andersen, 1912, comprises several medium-sized fruit-bat species endemic to forested areas of Sundaland and the Philippines. Specimens of Dyacopterus are sparsely represented in collections of world museums, which has hindered resolution of species limits within the genus. Based on our studies of most available museum material, we review the infrageneric taxonomy of Dyacopterus using craniometric and other comparisons. In the past, 2 species have been described—D. spadiceus (Thomas, 1890), described from Borneo and later recorded from the Malay Peninsula, and D. brooksi Thomas, 1920, described from Sumatra. These 2 nominal taxa are often recognized as species or conspecific subspecies representing these respective populations. Our examinations instead suggest that both previously described species of Dyacopterus co-occur on the Sunda Shelf—the smaller-skulled D. spadiceus in peninsular Malaysia, Sumatra, and Borneo, and the larger-skulled D. brooksi in Sumatra and Borneo. We further identify specimens of Dyacopterus from the large islands of Luzon and Mindanao in the Philippines as representatives of a distinctive new species, Dyacopterus rickarti. This new species differs from the Sundaic taxa in its much larger size, unique palatal ridge formula, and in qualitative craniodental features. The natural history of each species, so far as it is known, is briefly reviewed.
