The frog genus Uperoleia (Myobatrachidae) is species rich, with the greatest diversity in the northern monsoonal region of Australia. Due in part to their small body size, conservative morphology and distribution in diverse habitats, the genus is likely to harbor cryptic species. A recent study (Catullo et al. 2013) assessed region-wide genetic, acoustic and phenotypic variation within four species in northern Australia. Catullo et al. (2013) presented multiple lines of evidence that the widespread U. trachyderma comprises distinct allopatric western and eastern lineages within the Northern Deserts bioregion of Australia. Here we formally describe the western lineage as U. stridera sp. nov. and redescribe the eastern (type) clade as U. trachyderma. The new species can be distinguished from U. trachyderma by fewer pulses per call, a faster pulse rate, and the lack of scattered orange to red flecks on the dorsum. The description of U. stridera sp. nov. brings the number of Uperoleia species to 28, by far the largest genus in the Myobatrachidae, and further highlights the Australian monsoonal tropics as a region of high endemism.
姬蛙属（Myobatrachidae科）物种丰富，在澳大利亚北部季风区具有最高的多样性。部分由于它们体型小、形态保守且分布于多样的栖息地，该属可能存在隐存种。最近一项研究（Catullo等人，2013年）评估了澳大利亚北部四个物种在区域范围内的遗传、声学和表型变异。Catullo等人（2013年）提供了多条证据，表明分布广泛的糙皮姬蛙（U. trachyderma）在澳大利亚北部沙漠生物区系内包含不同的异域西部和东部谱系。在此，我们正式将西部谱系描述为新物种细纹姬蛙（U. stridera sp. nov.），并重新描述东部（模式）分支为糙皮姬蛙（U. trachyderma）。新物种可通过每次鸣叫的脉冲较少、脉冲速率较快以及背部缺乏分散的橙色至红色斑点与糙皮姬蛙区分开来。细纹姬蛙（U. stridera sp. nov.）的描述使姬蛙属物种数量增至28种，成为Myobatrachidae科迄今为止最大的属，并进一步凸显了澳大利亚季风热带地区作为一个高特有性的区域。
