The specific epithet is derived from the Ancient Greek words leukos "white" and ǒphrys "eyebrow".

[5] Following Clancey, the nominate subspecies is sometimes restricted to the Eastern Cape region, and the following subspecies are then distinguished from it:[6] The white-browed scrub robin measures 14.0–16.5 cm from bill tip to tail tip and the sexes are alike.

The tail is greyish brown to rufous, with a black subterminal band and white feather tips and corners.

[4] The white-browed scrub robin is found in Angola, Botswana, Burundi, Republic of the Congo, DRC, Djibouti, Eswatini, Ethiopia, Gabon, Kenya, Malawi, Mozambique, Namibia, Rwanda, Somalia, South Africa, South Sudan, Tanzania, Uganda, Zambia, and Zimbabwe.

It is present and usually common in any mesic to arid woodland or savanna, provided that there is cover, open scrub or thickets.

[4] As with some other scrub robin species, the tail is regularly flicked and fanned, and the wings may be drooped.

The cream-coloured eggs, measuring 20 x 14 mm, are blotched with brown and purple around the thicker end.
