Predatory mites from crops and pastures in South Africa: potential natural enemies of redlegged earth mite Halotydeus destructor (Acari: Penthaleidae) Author Halliday, R.

Hypoaspis spiculifer : Ryke, 1963 : 5 . Hypoaspis ( Hypoaspis ) spiculifer : Van Aswegen & Loots, 1970 : 189 . Hypoaspis ( Gaeolaelaps ) spiculifera ( sic ): Karg, 1989a : 118 . Specimens examined : Site 94­31, 1 female . Hypoaspis spiculifer was described from East Africa ( Berlese, 1918 ), was later collected from a straw heap at Potchefstroom by Ryke (1963) , and from a tree stump at Potchefstroom by Van Aswegen & Loots (1970) . It is assumed to be predatory on the basis of analogy with other species of Hypoaspis , but it is obviously rare, and unlikely to be important in regulating populations of its prey.
