Abstract

Species diversity can be underestimated due to a lack of regional studies and limitations in research methods. China is widely recognized as one of the primary hotspots for the biodiversity of freshwater mussels as it harbours a wealth of endemic species. Pseudocuneopsis was recently established to belong to the Unioninae subfamily within Unionidae and is endemic to China. Recent research has expanded the diversity and range of distribution of this genus. However, sufficient data is required to precisely determine the phylogenetic relationships within Pseudocuneopsis. This study conducted an integrative taxonomy using morphological, COI barcode, and complete maternal mitogenome data to clarify the taxonomy of Pseudocuneopsis. Both morphological and COI barcode data supported the validity of all Pseudocuneopsis species. Furthermore, a new species, Pseudocuneopsis yemaoi sp. n. was described from a tributary of the Man River in Hubei, China. Mitochondrial phylogenomic analyses showed that P. yemaoi was closely related to P. sichuanensis and resolved phylogenetic relationship as (P. capitata + (P. yangshuoensis + (P. sichuanensis + P. yemaoi))). Our results highlight the significance of utilizing integrative classification methods. Moreover, we propose enhancing the research and preservation measures of minor streams in China, as these streams may house distinctive species.

重新审视假楔鲃属（双壳类，联合科）：形态学、线粒体系统发生组学和一个新物种的描述

由于缺乏区域研究和研究方法的局限性，物种多样性可能被低估。中国被公认为淡水贻贝生物多样性的主要热点地区之一，因为这里有丰富的特有物种。假楔贻贝（Pseudocuneopsis）最近被确定为属于贻贝科（Unionidae）中的Unioninae亚科，是中国特有的物种。最近的研究扩大了该属的多样性和分布范围。然而，要精确地确定假楔蛾属的系统发育关系还需要足够的数据。本研究利用形态学、COI条形码和完整的母体有丝分裂基因组数据进行了综合分类，以明确假楔蛾属的分类。形态学和 COI 条形码数据都支持所有 Pseudocuneopsis 物种的有效性。此外，还描述了产自中国湖北漫江支流的一个新物种 Pseudocuneopsis yemaoi sp.线粒体系统发生组分析表明，P. yemaoi与P. sichuanensis亲缘关系密切，其系统发生关系为（P. capitata + (P. yangshuoensis + (P. sichuanensis + P. yemaoi)）。我们的结果凸显了利用综合分类方法的意义。此外，我们建议加强对中国小溪流的研究和保护措施，因为这些溪流可能蕴藏着独特的物种。

期刊介绍： Zoologica Scripta publishes papers in animal systematics and phylogeny, i.e. studies of evolutionary relationships among taxa, and the origin and evolution of biological diversity. Papers can also deal with ecological interactions and geographic distributions (phylogeography) if the results are placed in a wider phylogenetic/systematic/evolutionary context. Zoologica Scripta encourages papers on the development of methods for all aspects of phylogenetic inference and biological nomenclature/classification. Articles published in Zoologica Scripta must be original and present either theoretical or empirical studies of interest to a broad audience in systematics and phylogeny. Purely taxonomic papers, like species descriptions without being placed in a wider systematic/phylogenetic context, will not be considered.
