N2 - Frogs of the subgenus Vatomantis Glaw and Vences, 2006 form a monophyletic group within the genus Gephyromantis Methuen, 1920 in the family Mantellidae, endemic to Madagascar and Mayotte. In anurans, vocalization is often a valuable character complex for taxonomical classification since it is an efficient premating isolation mechanism, and to add to the bioacoustic knowledge on Madagascar's frogs we here provide a description of the advertisement calls of three sympatric species in the subgenus Vatomantis: Gephyromantis webbi (Grandison, 1953), G. rivicola (Vences, Glaw and Andreone, 1997) and G. silvanus (Vences, Glaw and Andreone, 1997). Calls of all three species were recorded the same day at the same temperature, in sympatry along a small stream in a forest fragment near Andranofotsy, allowing for a direct comparison. The call of G. webbi is the shortest, with long inter-call interval length. Overall, the calls of G. rivicola and G. silvanus show more similarities to one another than to that of G. webbi.
