Abstract The first account of the predaceous diving beetles or Dytiscidae of Jordan is presented. Altogether 25 species are listed, although the occurrence of two of them remains doubtful. Nine species are recorded from the territory of Jordan for the first time, and the first precise locality data are provided for an additional seven species. Bidessus anatolicus Wewalka, 1972 and Nebrioporus stearinus (Kolenati, 1845) recorded recently from Jordan based on misidentification are removed from the list. If available, habitat information is provided for recently collected species. The zoogeographical patterns of the region are briefly summarised.

约旦的掠食性潜水甲虫（鞘翅目：Dytiscidae）

摘要 首次描述了约旦的捕食性潜水甲虫或龙虱科。总共列出了 25 个物种，尽管其中两个物种的出现仍然值得怀疑。约旦境内首次记录了 9 个物种，并为另外 7 个物种提供了第一个精确的位置数据。Bidessus anatolicus Wewalka, 1972 和 Nebrioporus stearinus (Kolenati, 1845) 最近基于错误识别从约旦记录的物种被从列表中删除。如果可用，提供最近收集的物种的栖息地信息。简要总结了该地区的动物地理格局。
