Locality and type material. Holotype female, 3 paratype females and 2 paratype males, from Bauhinia galpinii , Limpopo Province, Die Eiland near Gravelotte, South Africa, 25-V-1983, M.K.P. Smith Meyer, deposited at NCA-PPRI; 1 paratype female and one paratype male, from B. galpinii , Limpopo Province, Gravelotte River, South Africa, 25-V-1983, E. A. Ueckermann, deposited at NCA-PPRI.

Etymology. The name galpinii refers to the host plant on which the types of this species were found.

Remarks. Typhlodromus (A.) persianus (McMurtry) and T. (A.) theroni Ueckermann & Loots differ from this new species by having seta Z4 at least as long as the distance between its base and the base on S5 and macroseta on basitarsus of leg IV knobbed. Furthermore, T. (A.) persianus has seta Z5 knobbed. Typhlodromus (A.) wrenschae Ueckermann & Loots also differs from this new species by having seta S2 0.4 times as long as the distance between its base and the base of S4; setae Z5, JV5 and StIV knobbed.
