ABSTRACT Leptodactylid frogs are phenotypically diverse, widely distributed across the Neotropics, and are known to harbor high levels of cryptic species diversity. This is especially true in Adenomera, where several candidate species have been recognized in a genetics-based study. Here we describe a new Amazonian species of Adenomera, which corresponds to one of the lineages previously identified as a candidate species (“sp. F”). Adenomera phonotriccus, n. sp., differs from all 18 recognized congeners by its unique advertisement call. Moreover, this species can be distinguished from nearly all congeners (except A. cotuba and A. lutzi) in having antebrachial tubercles on the undersides of its forearms. The distribution of A. phonotriccus seems to be restricted to the Araguaia- Xingu interfluve, in the eastern portion of the Brazilian state of Pará. Additional sampling effort on the right margin of the Araguaia River and along the Xingu River drainage should clarify the distribution of A. phonotriccus and perhaps result in the discovery of additional undescribed species of Adenomera in a region with high biological diversity.

来自巴西帕拉州的亚马逊新种 Adenomera（Anura：Leptodactylidae）：青蛙中的暴君声音

摘要 Leptodactylid 青蛙的表型多样，广泛分布在新热带地区，并且已知具有高水平的隐秘物种多样性。在 Adenomera 中尤其如此，在一项基于遗传学的研究中已经识别出几个候选物种。在这里，我们描述了一种新的亚马逊物种 Adenomera，它对应于先前确定为候选物种（“sp. F”）的谱系之一。Adenomera phonotriccus, n. sp., 不同于所有 18 种公认的同类产品，其独特的广告调用。此外，该物种与几乎所有同类（A. cotuba 和 A. lutzi 除外）的区别在于其前臂下方具有前臂结节。A. phonotriccus 的分布似乎仅限于巴西帕拉州东部的 Araguaia-Xingu interfluve。
