AI Article Synopsis
- - The article revises the Delevea genus of water beetles, specifically focusing on recent collections from South Africa, highlighting new findings and data.
- - Two previously known species (D. bertrandi and D. namibiensis) are reported to have extended ranges, being endemic to specific areas in South Africa and Namibia.
- - Two new species, D. madiba and D. namaqua, are introduced, with D. namaqua being the largest described species in its suborder at nearly 2.85 mm long, and both are currently known only from their original locations.
Article Abstract
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.
