摘要。马达加斯加被广泛认为是生物多样性的热点，但淡水双壳类动物最近只受到有限的关注。根据对来自15个主要博物馆的记录的检查和文献综述，至少有9种淡水贻贝（软体动物：Bivalvia: Unionoida）被报道来自非洲东部印度洋的马达加斯加或马斯克林群岛（特别是留尼汪岛或毛里求斯）。然而，数据的质量通常很差。这些物种记录中的7个被认为是来自其他地区的已知分类群的错误报告，或者是命名的可疑物种。没有马斯卡林人的记录被认为是有效的。剩下的两个物种，Etheria elliptica Lamarck 1807和Unio geayi Germain 1911 （= Coelatura geayi）都来自马达加斯加，后者是在关于Unionidae家族起源的两种不同假设的背景下讨论的，绰号为“走出非洲”和“进入非洲”。为了强调该物种与其他非洲热带淡水贻贝谱系的区别，我们为格亚伊大学引进了Germainaia gen. 11。讨论了Germainaia可能代表马达加斯加海蝇科的可能性，但由于缺乏完整的数据，新属在科水平上被留在incertae sedis。新分类群：Germainaia Graf和Cummings
ABSTRACT. Madagascar is widely recognized as a biodiversity hotspot, but the freshwater bivalves have received only limited recent attention. Based upon examination of records from 15 major museums and a literature review, at least nine species of freshwater mussels (Mollusca: Bivalvia: Unionoida) have been reported from either Madagascar or the Mascarene Islands (specifically, Reunion or Mauritius) in the Indian Ocean, east of Africa. The quality of the data, however, is generally poor. Seven of those species records are regarded as either erroneous reports of taxa known from other regions or as nomina dubia. No records from the Mascarenes are considered to be valid. The two remaining species, Etheria elliptica Lamarck 1807 and Unio geayi Germain 1911 (= Coelatura geayi) are both from Madagascar, and the latter is discussed in the context of two alternative hypotheses for the origin of the family Unionidae, nicknamed “Out of Africa” and “Into Africa.” Germainaia gen. nov. is introduced for Unio geayi to emphasize the distinction of that species from other Afrotropical freshwater mussel lineages. The possibility that Germainaia may represent the Hyriidae in Madagascar is discussed, but the new genus is left incertae sedis at the family-level in the absence of complete data.
