We present an illustrated key to the exuviae and final stadium larvae of the dragonflies of Namibia. We have also included some taxa from neighbouring areas, which have not been recorded in Namibia yet. The key is therefore applicable also in southern Angola, most of Botswana and the Northern Cape province of South Africa. It includes  identification characters of taxa hitherto undescribed, viz. Lestes pallidus, Pseudagrion deningi, P. rufostigma, Ictinogomphus dundoensis, Crenigomphus cornutus, C. kavangoensis, C. hartmanni, Paragomphus cataractae, P. elpidius, P. sabicus, Mastigogomphus dissimilis, Anax bangweuluen sis, and Phyllomacromia overlaeti, and for the first time keys for some widespread African species pairs, such as Tramea basilaris and T. limbata, and Zygonyx torridus and Z. natalensis. However, the larvae of many species and even four out of 50 genera occurring in Namibia are still unknown. Therefore, this key remains preliminary.
