Many higher groups of plants and animals show distributional patterns which have been shown or have at some point in time been suggested to be correlated with plate tectonics and the ancient supercontinents Laurasia and Gondwana. Here, we study the family of squeak beetles (Coleoptera: Adephaga: Hygrobiidae) and its enigmatic distribution pattern, with one species in the Western Palearctic, one in China and four in Australia. We present a molecular phylogeny including five of the six extant species, showing the monophyly of the Australian radiation. We use a molecular clock approach, which indicates that Hygrobiidae is an ancient group dating back to the breakup of Pangea and discuss the possibility of vicariance as explanation for its current distribution.
许多高等植物和动物群体表现出的分布模式已经被证明或在某个时候被认为与板块构造和古老的超大陆劳亚古陆和冈瓦纳古陆有关。在这里，我们研究了 squeak 甲虫科（鞘翅目：多食亚目：水龟甲科）及其神秘的分布模式，其中一种分布在西古北区，一种分布在中国，四种分布在澳大利亚。我们展示了一个包括现存的六个物种中的五个的分子系统发育，表明澳大利亚辐射是单系的。我们使用分子钟方法，表明 Hygrobiidae 是一个古老的群体，可追溯到泛古陆分裂时期，并讨论了作为其当前分布的隔离分化解释的可能性。
