This species was previously known as D. setosus uncinatus (Attems, 1928). It was originally recorded from the Howick and Rietvlei areas and Kranskop in KwaZulu-Natal (Attems 1928). More recently (1999) it was recollected at one locality in the Karkloof Forest complex near Howick, and from Ngoye Forest. It is likely to be confined to forest habitat, and to have a disjunct distribution between Karkloof and Ngoye. In the Karkloof most of the forest is on privately owned land, where it is threatened to some extent by illegal logging, alien plant invasions, grazing and by being surrounded by plantations. Subpopulations of D. natalensis in smaller patches of forest in the Rietvlei area are likely to have been lost through exploitation. Ngoye Forest is managed by KZN Wildlife, but the forest is used for grazing by local communities, and wood and medicinal plants are harvested. Kranskop is in a densely inhabited, rural area in the Tugela Valley. The forests here are used for wood for fuel and building, for medicinal plants and for grazing.
