Djalma cancelled out Youssef Msakni’s first-half penalty to earn Angola a point against Tunisia in the Africa Cup of Nations.
The 32-year-old fired home on the rebound after goalkeeper Farouk Ben Mustapha failed to hold on to Mateus’ goal-bound effort.
Msakni had given Tunisia the lead from the spot 11 minutes before half-time.
Mali beat Mauritania 4-1 in Group E’s other game on Monday.
