Key identification features:

Face is greyish with the labrum light yellow with a dark brown lip. Frons very rounded, with two short, sharp horns, grey, dusted with dark brown. Tthese hornsmay be the origin of the name "Horned"  rockdweller) Vertex very high, with two, short horns, dark brown, with light yellowish grey base. The eyes are dark brown with spotted grey below.

The mottled colouring and the light patch on S7 is unmistakable. The horn like protrusions on the frons and vertex is very clear to see.

Localized but records from northern and north eastern provinces are increasing and possible range extension father south into central and southern KZN. Previously, thought to be a species from the Mpumalanga lowveld areas.
Rocky outcrops and domes with rain pools, in which it breeds but also seen laying eggs in river pools, close to rocky, fast, lowveld rivers. Will easily settle on man-made structures like brick walls and other cement structures like the walls of dams resembling rocky outcrops.
