We describe two new species of poison frog from central and southern Peru that have been referred to as Ameerega picta, A. hahneli, or A. altamazonica throughout the past thirty years. Our phylogenies generated with genomic data provide strong support that the two new species are successive sisters to two described taxa, A. rubriventris and A. altamazonica, and collectively comprise the Ameerega rubriventris complex. The first new taxon, Ameerega panguana sp. nov., can be distinguished from all other Ameerega by its combination of a unique white venter and an advertisement call of 1-2 notes per second. The second new taxon, Ameerega imasmari sp. nov., is the only cryptically colored Ameerega species that is disttributed across the Fitzcarrald Arch in Southern Peru which possesses a 'peep' advertisement call consisting of 3-4 notes per second and a dominant frequency of 4.3-4.5 kHz. Within the Ameerega rubriventris complex, we observed differences between species in their ventral coloration, tympanum diameter, and call, which suggest that these taxa are reproductively isolated from each other.
我们描述了来自秘鲁中部和南部的两种新的箭毒蛙物种，在过去三十年里它们一直被称为饰纹箭毒蛙、哈氏箭毒蛙或亚马孙高地箭毒蛙。我们利用基因组数据生成的系统发育树有力地支持了这两个新物种是已描述的两个分类单元——红腹箭毒蛙和亚马孙高地箭毒蛙的连续姐妹种，并共同构成了红腹箭毒蛙复合体。第一个新分类单元，潘瓜纳箭毒蛙（Ameerega panguana sp. nov.），可通过其独特的白色腹部以及每秒1 - 2个音符的求偶鸣叫与所有其他箭毒蛙区分开来。第二个新分类单元，伊马斯马里箭毒蛙（Ameerega imasmari sp. nov.），是唯一一种分布在秘鲁南部菲茨卡拉尔德群岛的颜色隐秘的箭毒蛙物种，其“唧啾”求偶鸣叫每秒由3 - 4个音符组成，主频为4.3 - 4.5千赫。在红腹箭毒蛙复合体中，我们观察到不同物种在腹部颜色、鼓膜直径和鸣叫方面存在差异，这表明这些分类单元彼此之间存在生殖隔离。
