Akentrobuthinae, a new subfamily of the Buthidae, is erected for Akentrobuthus leleupi gen. et sp. nov. This new subfamily is typified by a distinctive combination of characters among which are: subpentagonal sternum; suboval stigmata; distal middle lamellae of pectines rounded, fulcra absent; tibial spurs absent; the two basal teeth of the superior row of the chelicera movable finger reduced, the proximal one being extremely reduced or absent in most adult specimens. Akentrobuthus leleupi is an endemic humicolous scorpion from primary and secondary forests of the Kivu Province in eastern Zaïre. With an adult body length of 16 mm it is one of the smaller species of Buthidae known. Only females have been found so far. Apically perforated sensory macro­setae, for which a contact chemoreceptor function is proposed, are descriptionbed as a remarkable feature of this new species, the only other scorpion known to have these specialized setae being Microtityus rickyi Kj.-Waer., 1966, a neotropical buthid endemic to Trinidad.
