Distribution and habitat. Nemia lata is confined to the Northern Cape Province, South Africa and occupies small range in north-western Namaqualand ( Fig. 176 ). The range falls within the Namaqualand Sandveld Bioregion ( Mucina & Rutherford 2006). The habitat in the area is characterised by winter rains and regular storms with low annual precipitation (50–80 mm). The vegetation cover is mainly succulent shrubs ( Mucina & Rutherford 2006).
