Abstract: In the years 1992 and 1993, the Austrian entomologist Michael Madl collected semiaquatic Hemiptera on Nosy Boraha (Île Sainte Marie), a small island near the north-eastern coast of Madagascar. The collected material contains five species of Rhagovelia Mayr, 1865, two of which are new to science. Both Rhagovelia madli sp. nov. and Rhagovelia kalalaoensis sp. nov. belong to the R. tesari species group. The other three species reported from the island are R. madari Hoberlandt, 1941, R. reuteri Hoberlandt, 1951, and R. tesari Hoberlandt, 1941.
