The taxonomical study of the Coleoptera Platynotina of Madagascar is presented and illustrated. The Madagascan Platynotina include three main groups: (I) the genera Zidalus Mulsant et Rey (three species) and Anchophthalmops Koch (one species) occurring in both Madagascar and the African continent; (II) the endemic genus Lechius Iwan (three species), and (III) the Madagascan "melanocratoid" generic group (eight genera, 30 species). The Madagascan Platynotina comprise 37 species in 11 genera. The occurrence in Madagascar of one species, Anchophthalmops menouxi (Mulsant et Rey, 1853) needs confirmation. Bilingual French-English identification keys to genera and species are presented.
