An integrative taxonomic analysis based on morphology, color pattern, and the mitochondrial gene ND2 recovered four new species of Hemiphyllodactylus Bleeker that are endemic to the Shan Plateau or Salween Basin in eastern Myanmar. Hemiphyllodactylus ngwelwini sp. nov. from the Shan Plateau is part of the earlier described "eastern Myanmar clade" renamed herein as the north lineage and H. kyaiktiyoensis sp. nov. and H. pinlaungensis sp. nov. of the Shan Plateau and H. zwegabinensis sp. nov. of the Salween Basin compose an entirely new Burmese clade herein referred to as the south lineage. Although the north and south lineages come within 46 km of one another on the Shan Plateau, they are not sister lineages but sequentially separated by two lineages from Yunnan, China and another from northwestern Thailand. Hemiphyllodactylus zwegabinensis sp. nov. is the first species of this genus to be recorded from the Salween Basin and is known only from a wind-blown cloud forest on the top of the insular, karstic mountain Zwegabin in Kayin State. All other Burmese species except for H. typus, are endemic to the various localities throughout the Shan Plateau. These four new species bring the total number of Hemiphyllodactylus in Myanmar to at least 10 which is certainly an extreme underestimate of the diversity of this genus given that we discover new species at every upland locality we survey.
基于形态学、色斑以及线粒体基因ND2的综合分类学分析,发现了四种新的半叶趾虎属(Hemiphyllodactylus Bleeker)物种,它们是缅甸东部掸邦高原或萨尔温江流域的特有物种。来自掸邦高原的恩格韦尔维半叶趾虎(Hemiphyllodactylus ngwelwini sp. nov.)是先前描述的“缅甸东部分支”的一部分,在此重新命名为北支系;掸邦高原的基亚克蒂约半叶趾虎(Hemiphyllodactylus kyaiktiyoensis sp. nov.)、平朗半叶趾虎(Hemiphyllodactylus pinlaungensis sp. nov.)以及萨尔温江流域的泽韦加宾半叶趾虎(Hemiphyllodactylus zwegabinensis sp. nov.)构成了一个全新的缅甸分支,在此称为南支系。尽管北支系和南支系在掸邦高原上彼此距离不到46公里,但它们并非姐妹支系,而是被来自中国云南的两个支系以及另一个来自泰国西北部的支系依次分隔开来。泽韦加宾半叶趾虎(Hemiphyllodactylus zwegabinensis sp. nov.)是该属中首个在萨尔温江流域被记录的物种,仅在克耶邦泽韦加宾岛状岩溶山顶的一片风吹云雾林中被发现。除了典型半叶趾虎(H. typus)外,所有其他缅甸物种都特有于掸邦高原的各个地方。这四个新物种使缅甸的半叶趾虎总数至少达到10种,鉴于我们在每个调查的高地地区都发现了新物种,这肯定极大低估了该属的多样性。
