This species was first reported as Typhlodromus ( Anthoseius) kazachstanicus Wainstein in Algeria by Athias- Henriot ( 1960 b), but then identified as a new species by Wainstein & Arutunjan ( 1967). Nothing is known of its biology. This is the second report of this species in the world.

Specimens examined: 2003, Ras El Ma on Cydonia oblonga ( Rosaceae ) ( 1 female), Silene sedoides ( Caryophyllaceae ) ( 1 female), near Larache on Chamaerops humilis ( Arecaceae ) ( 1 female), Saïdia on Lygos raetrum ( Fabaceae ) ( 1 female).

Previous records: Algeria.
