Sumario:For the recently established genus Madagopsina (Diopsidae, stalk-eyed flies), Madagopsinamakayensis Feijen, Feijen & Feijen, sp. nov. is described from Madagascar. A concise catalogue is given for the genus and an identification key is presented for its six species. The differential character states are listed for the two species groups of the genus: the Madagopsinaapollo species group and the Madagopsinaapographica species group. The intrageneric relations are discussed based on morphology, geometric morphometrics analysis of wing shape, and allometric data for eye span against body length. Each of these three procedures places the new species in the M.apollo species group with Madagopsinaparvapollina as its closest relative. New records are presented for M.apographica and M.parvapollina.
