Eucamaragnathus desenderi sp. n., a new ground beetle species of the tribe Hiletini, is described from eastern and southern Africa and dedicated to the recently deceased Belgian carabidologist Konjev Desender. The new taxon is known so far from localities in Zambia (Mukuku, southeast of Mansa) and in South
Africa (Bothaville, south of Klerksdorp). The new species belongs to the E. castelnaui group and is characterized by shape of pronotum, smooth or sparsely punctate pronotal transverse impression, characters of male genitalia and elytral striae continued to the apex. Illustrations of the habitus, the median lobe and its
internal sac and several other morphological features are presented. An updated identification key to the African Eucamaragnathus species is given.
