Probergrothius sexpunctatus is a species of true bug found in West-Central Africa.

The name has been misattributed for many decades to a related species, Probergrothius angolensis, a species that occurs farther to the south, and which feeds on the Welwitschia plant.

[1] P. sexpunctatus, as its name suggests, has six prominent black spots on its wings (3 per wing; 2 anteriorly and 1 posteriorly).

This distinguishes it from the visually similar P. angolensis, where the two anterior wing spots are typically fused, making four wing spots (2 per wing; 1 anteriorly and posteriorly).

P. sexpunctatus also typically has a reddish pronotum and legs, which are black (or almost black) in P. angolensis, however this character is less reliable.
