Kazimierzidae Nxele & Plisko, 2016

This recently erected family of earthworms, which includes 25 nominal species all in the single genus Kazimierzus, is restricted to the Western Cape and Northern Cape provinces, including the Namaqualand areas, along the Atlantic region of South Africa. This is a hotspot of biodiversity (Myers et al. 2000), with considerable topographical and botanic diversity, which will probably still lead to the discovery of new earthworm species, as observed by Nxele et al. (2017).
