From a well-documented study of two sympatric sibling species of singing gomphocerine grasshoppers, Perdeck (1958) reached the surprisng conclusion that reproductive isolation between them resulted almost exclusively from differences in acustic behavior. In the present work, comparison of the sibling gomphocerine grasshoppers D. curvicercus, D. jagoi jagoi and D. genei littoralis revealed ecographical, temporal, ethological, structural and cytological differences which could account for failure of the species to interbreed.
