Abstract

Abstract. The genus Proceratophrys currently comprises 40 species, of which five are distributed within the Caatinga domain and associated phytophysiognomies along northeastern Brazil. During field surveys at high altitudinal sites in Boqueirão da Onça region, northern Bahia state, we collected individuals of Proceratophrys that could not be assigned to any species currently known to occur within the Caatinga, which we describe herein. The new species can be diagnosed from remaining congeners based on vocalization, adult and tadpole morphology, and is also supported by molecular data (mitochondrial 16S, cytochrome b, and nuclear rhodopsin). We recovered the new species nested in the clade composed of species distributed within the Caatinga domain and associated phytophysiognomies, exhibiting a minimum of 7% of genetic divergence for the 16S gene in comparison to all its congeners. The new species seems to be restricted to high altitude locations (above 800 m) at the Boqueirão da Onça region, which represents the largest remaining contiguous Caatinga remnant (∼986,000 ha) being classified as of extreme biological importance.

巴西巴伊亚州北部Boqueirão da OnçA原角龙属一新种（无尾目：齿龙科）

摘要Proceratophrys属目前包括40个物种，其中5个分布在巴西东北部的Caatinga地区和相关的植物区系内。在巴伊亚州北部Boqueirão da Onça地区的高海拔地区进行实地调查期间，我们收集了Proceratophrys的个体，这些个体无法被分配到目前已知发生在Caatinga的任何物种中，我们在本文中对此进行了描述。新物种可以根据发声、成年和蝌蚪形态从剩余的同源物中诊断出来，也有分子数据（线粒体16S、细胞色素b和核视紫红质）支持。我们恢复了嵌套在由分布在Caatinga结构域内的物种和相关的植物相学组成的分支中的新物种，与所有同源基因相比，16S基因表现出至少7%的遗传差异。该新物种似乎仅限于Boqueirão da Onça地区的高海拔地区（800米以上），该地区代表了目前最大的连续Caatinga遗迹（～986000公顷），被归类为具有极端生物重要性。

期刊介绍： The Journal of Herpetology accepts manuscripts on all aspects on the biology of amphibians and reptiles including their behavior, conservation, ecology, morphology, physiology, and systematics, as well as herpetological education. We encourage authors to submit manuscripts that are data-driven and rigorous tests of hypotheses, or provide thorough descriptions of novel taxa (living or fossil). Topics may address theoretical issues in a thoughtful, quantitative way. Reviews and policy papers that provide new insight on the herpetological sciences are also welcome, but they must be more than simple literature reviews. These papers must have a central focus that propose a new argument for understanding a concept or a new approach for answering a question or solving a problem. Focus sections that combine papers on related topics are normally determined by the Editors. Publication in the Long-Term Perspectives section is by invitation only. Papers on captive breeding, new techniques or sampling methods, anecdotal or isolated natural history observations, geographic range extensions, and essays should be submitted to our sister journal, Herpetological Review.
