The Southern African endemic torridincolid water beetle genus Delevea Reichardt, 1976 is revised, based largely on recently collected material from the Republic of South Africa. Significant range extensions are provided for the two previously described species, Delevea bertrandi Reichardt, 1976 and D. namibiensis Endrödy-Younga, 1997, these taxa apparently being endemic to the Fynbos Biome in the Western Cape Province and semi-arid, summer rainfall, areas of the Great Escarpment in Namibia and South Africa, respectively. In addition, two new species, Delevea madiba sp. nov. and D. namaqua sp. nov. are described from winter rainfall areas of Namaqualand in the Northern Cape Province. Both species are currently only known from their type locality and, at up to 2.85 mm in adult body length, D. namaqua sp. nov. is the largest described extant species of the suborder Myxophaga.
修订了南非地方性酷热鞘翅目水甲虫属Delevea Reichardt，1976，主要基于最近从南非共和国收集的材料。为之前描述的两种物种Delevea bertrandi Reichardt，1976 和 D. namibiensis Endrödy-Younga，1997 提供了显著的分布范围扩展，这些分类单元显然是西开普省 Fynbos 生物群以及纳米比亚和南非大悬崖夏季降雨半干旱地区的地方性物种。此外，还从北开普省 Namaqualand 的冬季降雨区描述了两个新物种Delevea madiba sp. nov. 和 D. namaqua sp. nov.。这两个物种目前仅在其模式产地被发现，而在成年体长达 2.85 毫米的情况下，D. namaqua sp. nov. 是已知的最大的现存亚目 Myxophaga 物种。
