Material examined. MADAGASCAR: NOඌ¥ BORΑΗΑ: 9 ♁♁ 8 ♀♀ (macropterous), Forêt de Kalalao, 22.xi.1993, leg. M. Madl ( NHMW). Additional material examined. MADAGASCAR: FΙΑΝΑRΑΝΤඌOΑ PROνΙΝർĽ: 10 ♁♁ 12 ♀♀ (apterous), Ranomafana, 6–10.i.1998, leg. P. Pacholátko ( NHMW); 5 ♁♁ 5 ♀♀ (apterous), Ionilahy, tributary of Ionilahy river, 21.iv.2011, leg. R.

Notes. Rhagovelia reuteri was described based on three specimens collected by C. Lamberton in Rogez (now called Andekaleka; fide PƟΓΗΕΜUඌ & AΝĐΕRඌΕΝ 2015) in the southern part of Taomasina Province. The excellent, detailed illustrations of the apterous male provided by HƟΒΕRΓΑΝĐΤ (1951) allow a safe species identification. We have also studied three large series of this species from Fianarantsoa Province for comparison (identification of one series has been confirmed by direct comparison with the holotype by the first author in the past).

The specimens from Nosy Boraha are variable in size; leg colour is slightly darker than described for the types. Small males ( Fig. 4 ) lack the tooth at the base of the metatibia that is prominent in large males as described for the types.
