Currently, 58 species are assigned to the genus , with 70% of its diversity described just in the last two decades, with many additional species likely unnamed. The continuous description of these new species represents a fundamental step for resolving the taxonomy and ensuring the future conservation of the genus.
Using molecular, acoustic, and morphological evidences, we describe a new species of from Teles Pires River region, southern Amazonia, and provide accounts on the population of found sympatrically with the new species.
The new species is distinguished from its congeners by the coloration of thighs, venter, dorsum, and dark lateral stripe. It has four types of calls, with advertisement calls formed by relatively long trills with a mean duration of 2.29 s ± 0.65, mean of 39.93 notes ± 11.18 emitted at a mean rate of 17.49 ± 0.68 notes per second, and mean dominant frequency of 5,717 Hz ± 220.81. The genetic distance between the new species and its congeners in a fragment of the 16S mitochondrial fragment ranged between 13.2% () to 21.3% (). The sympatric population fits its morphology and acoustic with the nominal , but presents a relatively high genetic distance of nearly 6.5%, raising questions on the current taxonomy of this species.
目前，该属已被认定58个物种，其中70%的物种多样性是在过去二十年中被描述的，可能还有许多其他未命名的物种。这些新物种的不断描述是解决分类学问题和确保该属未来保护的关键一步。
利用分子、声学和形态学证据，我们描述了一种来自亚马逊河南部特莱斯皮里斯河地区的新物种，并介绍了与该新物种同域分布的该物种种群情况。
新物种在大腿、腹部、背部的颜色以及深色侧条纹方面与其同属其他物种不同。它有四种叫声类型，求偶叫声由相对较长的颤音组成，平均持续时间为2.29秒±0.65秒，平均发出39.93个音符±11.18个，平均发声速率为每秒17.49个±0.68个，平均主频为5717赫兹±220.81。在16S线粒体片段中，新物种与其同属其他物种之间的遗传距离在13.2%（）至21.3%（）之间。同域分布的该物种种群在形态和声学上与指名物种相符，但遗传距离相对较高，接近6.5%，这对该物种目前的分类学提出了疑问。
