[Dangerous scorpions from Niger].

Two dangerous scorpion species are responsible for the severe human envenomations in Niger, Leiurus quinquestriatus (H. et E.), the most abundant, and Androctonus aeneas C.L. Koch, less frequent and described in a Sahel country for the first time. Up to now, A. aeneas was known in North Africa only. Its venom is highly toxic for humans, similar to those of the most dangerous species living in Africa, such as L. quinquestriatus and other species belonging to the genus Androctonus, A. australis (L.) and A. mauretanicus (Poc.), for the envenoming treatment of which specific antivenoms are prepared. Taking into account the absence of a specific antivenom for A. aeneas, the paraspecific neutralising effect of these antivenoms should be tested.
