The study of unidentified
Coenosia specimens originating from African countries revealed four new
species, Coenosia lwiroa spec. nov. and Coenosia ovalia spec.
nov. from the Democratic Republic of the Congo, and Coenosia tarsomera
spec. Nov from Madagascar belong to the Coenosia semifumosa species
group sensu van Emden. Coenosia merua spec. Nov from Kenya, however,
belongs to the Coenosia calopoda species-group sensu van Emden. The new
spcies are described and distinguished from similar species.
