ency of the caustic potash-treated holotype genitalia it is difficult to confirm whether these lateral lobes are completely fused or not on the dorsal part. Superior appendages egg-shaped in lateral view and semitruncate in dorsal view. Aedeagus transparent having the typical downwards curving shape in lateral view withs lightly chitinized basal and a membranous apical half. A peculiar subapical ventral branch directed backwards to the posteroventral angle of the ninth segment producing an acutangular position to the main trunk of the aedeagus. The branch terminating in a bulbous apex forming an inverse fat L-shaped more sclerotized inclusion. However, the whole branch is more sclerotized than the very transparent membranous apical half of the aedeagus trunk. Besides this outstanding ventral branch two dorsal, thin, longitudinal, more sclerotized inclusions visible. Inferior appendages similar to the syriaca-balcanica and to the androconifera species groups. This is a distinct, presumably endemic African Adicella species. It is close to A. contorta Marlier, 1956 described from the nearby surroundings of Lake Tanganyika, but differs in details of nearly all structural features of the genitalia. Its inferior appendages with well-developed, almost hook-like inner subapical, back-curving processes lacking at A. contorta

. Its ventral branch with sclerotized inclusion on the aedeagus is also absent at A. contorta
