东方淡水蚌类(双壳纲:蚌科)的系统分类学知之甚少。在这里,我们提出了一个综合修订属TrapezoideusSimpson,1900年,以进一步了解该地区的淡水贻贝多样性。我们表明,Trapezoideusas目前限制是非单系,其前种属于其他六个属,其中一个是新的科学和描述在这里。我们认为Trapezoideus是一个单型属,由模式种T. Trapezoideus compactus,T. misellus,T.和T. peninsulatins转移到contradens属,T. subclathratusis移至Indonaia,T. Trapezoideus prashadiis是Arcidopsis footei的次异名,Trapezoideus dallianus,T. nesemanni,T. panhai,T. peguensis和两个新的物种被放置在Yaukthwagen。nov.本属似乎是西印度支那次区域的特有种。本文报道了两个新种,即白腰花Yaukthwa paiensissp. nov.和Y.无针的十一月,都是萨尔温江流域特有的我们的研究结果强调,东南亚是一个物种丰富的淡水贻贝多样性的热点,有许多当地特有的物种,这是需要特别的保护工作。
The systematics of Oriental freshwater mussels (Bivalvia: Unionidae) is poorly known. Here, we present an integrative revision of the genusTrapezoideusSimpson, 1900 to further understanding of freshwater mussel diversity in the region. We demonstrate thatTrapezoideusas currently circumscribed is non-monophyletic, with its former species belonging to six other genera, one of which is new to science and described here. We recognizeTrapezoideusas a monotypic genus, comprised of the type species,T. foliaceus.Trapezoideus comptus,T. misellus,T. pallegoixi, andT. peninsularisare transferred to the genusContradens,T. subclathratusis moved toIndonaia, andT. thecais transferred toLamellidens.Trapezoideus prashadiis found to be a junior synonym ofArcidopsis footei.Trapezoideus dallianus,T. nesemanni,T. panhai,T. peguensis, and two species new to science are placed inYaukthwagen. nov. This genus appears to be endemic of the Western Indochina Subregion. The two new species,Yaukthwa paiensissp. nov. andY. inlenensissp. nov., are both endemic to the Salween River basin. Our results highlight that Southeast Asia is a species-rich freshwater mussel diversity hotspot with numerous local endemic species, which are in need of special conservation efforts.
