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).
