The Malagasy planthopper genus Paraflata is revised. To the three previously known species (P. seminigra, P. kingdomi and P. dewalschei) two new ones are added and described: P. masoalae sp. nov. and P. unispinosa sp. nov. Their distribution is discussed and a bipolar distribution (from mountain and coastal biotopes) is reported for P. dewalschei. During morphological investigations, several dead pupae of unidentified Lepidoptera Epipyropidae specimens were discovered attached to the planthopper abdomens. This is the first report for the genus Paraflata of these planthopper parasitic moths, which might be considered, in this particular interspecific interaction, rather as ectoparasites than as parasitoids.
