We show that the Wotjulum frog, Litoria watjulumensis (Copland, 1957), comprises two deeply divergent mitochondrial DNA lineages that are also reciprocally monophyletic for a nuclear gene locus and have discrete distributions. The taxa are differentiated in multivariate analysis of shape but show no appreciable differences in colour and pattern. The two taxa differ substantially in the degree of female biased sexual size dimorphism, with the western taxon showing considerably more pronounced dimorphism. We subsequently resurrect Litoria (Hyla) spaldingi (Hosmer, 1964) for populations from east of the Daly River system in the Northern Territory through to western Queensland and restrict L. watjulumensis to populations from the Kimberley region of north-western Australia and the Victoria River system of the western Northern Territory. The complex advertisement call of L. spaldingi is described for the first time.
我们表明，沃特朱卢姆蛙（Litoria watjulumensis）Copland, 1957）由两个深度分化的线粒体 DNA 谱系组成，这两个谱系在一个核基因座上也是互为单系的，并且具有离散的分布。这两个分类群在形态的多元分析中存在分化，但在颜色和图案上没有明显差异。这两个分类群在雌性偏性的性二型性程度上有很大的差异，西部分类群的二型性更为显著。随后，我们将分布于北领地达利河流域以东至昆士兰州西部的种群归为 Litoria (Hyla) spaldingi（Hosmer, 1964），而将分布于澳大利亚西北部金伯利地区和北领地西部维多利亚河流域的种群归为 L. watjulumensis。我们首次对 L. spaldingi 复杂的求偶叫声进行了描述。
