Abstract

Kassinula is a monotypic genus of small frog in the family Hyperoliidae, only represented by Kassinula wittei. This species morphologically resembles both Kassina Girard, 1853 and Afrixalus Laurent, 1944, and its taxonomic status has been debated for decades. It has previously been subsumed within Kassina, and is currently placed as a sister genus to Afrixalus, although it has not been included in any phylogenetic studies until now. This species is poorly represented in museum collections and is only known from fewer than 35 specimens from southern Democratic Republic of the Congo and adjacent Zambia. Newly collected material from central Angola, a range extension of 400–800 km west of previously known localities, allowed us to revisit the taxonomic placement of the genus with the aid of phylogenetic analysis and shed light on its geographic distribution, morphology and natural history. Although our phylogenetic analysis is limited to a single mitochondrial gene (16S), we place Kassinula in the subfamily Hyperoliinae and closely related to Afrixalus, with a high degree of confidence. Further phylogenetic studies are needed before formally synonymising Afrixalus with Kassinula.

德维特点击蛙的分类地位、分布和自然历史的新见解（Kassinula witti Laurent，1940）

小蛙属(Kassinula wittei)是小蛙科的一个单型属。该物种在形态上与Kassina Girard, 1853和Afrixalus Laurent, 1944相似，其分类地位已经争论了几十年。它以前被归入卡西纳，目前被列为非洲属的姐妹属，尽管直到现在它还没有被包括在任何系统发育研究中。这一物种在博物馆藏品中很少有代表性，仅在刚果民主共和国南部和邻近的赞比亚发现了不到35个标本。新收集的材料来自安哥拉中部，范围从以前已知的地点向西延伸400-800公里，使我们能够借助系统发育分析重新审视该属的分类位置，并阐明其地理分布、形态和自然历史。虽然我们的系统发育分析仅限于单个线粒体基因(16S)，但我们将Kassinula置于Hyperoliinae亚科中，并与Afrixalus密切相关，具有很高的可信度。在将Afrixalus与Kassinula正式同义之前，需要进一步的系统发育研究。

期刊介绍： African Zoology , a peer-reviewed research journal, publishes original scientific contributions and critical reviews that focus principally on African fauna in terrestrial, freshwater, and marine ecosystems. Research from other regions that advances practical and theoretical aspects of zoology will be considered. Rigorous question-driven research in all aspects of zoology will take precedence over descriptive research. The Journal publishes full-length papers, critical reviews, short communications, letters to the editors as well as book reviews. Contributions based on purely observational, descriptive or anecdotal data will not be considered. The Journal is produced by NISC in association with the Zoological Society of South Africa (ZSSA). Acceptance of papers is the responsibility of the Editors-in-Chief in consultation with the Editors and members of the Editorial Advisory Board. All views expressed are those of the author and not necessarily those of the Editors or the Department.
