We used molecular and morphological data to investigate the hidden diversity within the Hypsiboas semilineatus species group, and more specifically within H. geographicus, an allegedly widespread species in northern South America. As a result, the identity of H. geographicus was clarified, several candidate species were detected and one of them, from the eastern Guiana Shield, is described herein as a preliminary step to resolve the taxonomy of the group. Hypsiboas diabolicus sp. nov. is mainly distinguished from closely-related species by an acuminate snout in lateral view, well-developed webbing between fingers and toes, and unspotted carmine/crimson colouration on the concealed surfaces of legs, feet and hands in life. The tadpole of the new species is described and is characterized by a large A-2 gap, a mostly single row of large marginal papillae, and a dark brown to black colouration. We also describe the advertisement call of the new species, which is defined as a soft call consisting of short clusters of 2-3 chuckles with a dominant frequency ranging between 1.11-1.19 kHz. Hypsiboas diabolicus sp. nov. is currently known only from the eastern Guiana Shield, and is probably endemic to that region. The new species' range overlaps broadly with another candidate species referred to as H. aff. semilineatus 1. Our preliminary results stress out a high cryptic diversity in that species group and the need for a formal redescription of Hypsiboas geographicus based on more topotypic material than what is currently available to properly sort out the taxonomic status of several lineages in that clade.
我们利用分子和形态学数据来研究半线雨蛙物种组内隐藏的多样性，更具体地说是研究地理雨蛙（Hypsiboas geographicus）内部的多样性，地理雨蛙据称是南美洲北部广泛分布的一个物种。结果，地理雨蛙的身份得以明确，检测到了几个候选物种，其中一个来自圭亚那盾形地东部，本文将其作为解决该物种组分类学问题的初步步骤进行描述。恶魔雨蛙（Hypsiboas diabolicus）新物种主要通过以下特征与近缘物种区分开来：侧面观吻部呈尖状，指、趾间有发达的蹼，生活时腿部、足部和手部隐蔽面无斑点，呈深红色/绯红色。描述了新物种的蝌蚪，其特征为A-2间隙大，大多为单排大的边缘乳突，颜色为深棕色至黑色。我们还描述了新物种的求偶鸣叫，其定义为一种柔和的鸣叫，由2-3声短的咯咯声组成的短簇，主频在1.11-1.19千赫兹之间。恶魔雨蛙新物种目前仅在圭亚那盾形地东部被发现，可能是该地区特有的。新物种的分布范围与另一个被称为地理雨蛙近似种1（H. aff. semilineatus 1）的候选物种广泛重叠。我们的初步结果强调了该物种组中存在高度的隐性多样性，以及需要基于比目前可用的更多的地模标本对地理雨蛙进行正式重新描述，以便正确梳理该分支中几个谱系的分类地位。
