abstract
Examination of unidentified Muscidae collected in Madagascar between 2011 and 2017 revealed seven Coenosia species that are new to science. Two species, Coenosia abdomaltoa spec. nov. and Coenosia ambrea spec. nov. belong to the C. humilis species group sensu van Emden, three others, Coenosia bohita spec. nov., Coenosia mafascia spec. nov. and Coenosia ranoma spec. nov., are members of the semifumosa-group, and Coenosia exima spec. nov. and Coenosia madaxenia spec. nov. were assigned to the strigipes species-group. The new taxa are described and the key features for distinguishing them from similar species from the respective species group are listed.
