Abstract

Abstract. Boana bischoffi was originally described from the Brazilian state of Rio Grande do Sul and has Boana multilineata from São Paulo as a junior synonym. The history of its nomenclature reflects the varying interpretation of the dorsal color pattern of the two different populations. We reevaluate the problem of taxonomic recognition of Boana multilineata based on molecular, morphometric, and acoustic data. The molecular data revealed two major clades that are partially concordant with the morphological and acoustic differentiation. Morphometric analyses revealed elements of differentiation between populations in snout–vent length (SVL) and head shape, which were patterns not detected previously. Discrimination considering call features was substantial, even complete in a discriminant analysis. Despite these differences, we refrain from resurrecting the name B. multilineata due to the existence of putative introgression zones, the effect of SVL in call dominant frequency, and lack of taxonomically relevant differences. Boana bischoffi might represent a case of incipient speciation.

Boana bischoffi（Anura，Hylidae）的种群分化：利用分子、形态学和声学数据重新审视问题

摘要Boana bischoffi最初被描述为来自巴西南里奥格兰德州，并将来自圣保罗的Boana multilista作为初级同义词。其命名的历史反映了对两个不同种群背部颜色模式的不同解释。基于分子、形态计量学和声学数据，我们重新评估了多线鲍属的分类识别问题。分子数据揭示了两个主要的分支，它们与形态和声学分化部分一致。形态计量学分析揭示了种群在鼻喷口长度（SVL）和头部形状方面的分化因素，这是以前没有检测到的模式。在判别分析中，考虑呼叫特征的判别是实质性的，甚至是完整的。尽管存在这些差异，但由于假定的渗入区的存在、SVL在呼叫优势频率中的影响以及缺乏分类学相关的差异，我们避免重新命名B.multileata。Boana bischoffi可能代表了一个早期物种形成的例子。

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.
