Libengaia (Libengaia) Linnavuori

Remarks. This subgenus at present is confined to Central and West Africa. Linnavuori (1969) included five species including four new species from the Democratic Republic of the Congo. In this paper we describe five new species, three from Cameroon and two from Nigeria. The subgenus can be recognized by the following combination of characters: crown medially longer than next to eyes; subgenital plates with apical membranous (less sclerotized) thin appendage; style apophysis often with truncate apex and rounded or poorly developed preapical lobe; dorsal wall of aedeagal atrium less well developed and differentiated; aedeagus with shafts without apical thin process, preatrium not differentiated well from base of ventral process; ventral process forked near distal region.
