Geographic differentiation in male calling song of Isophyamodestior (Orthoptera, Tettigoniidae, Phaneropterinae).

ABSTRACT: We studied the songs and morphology of the stridulatory file of Isophyamodestior across its complete geographic range, in order to test our hypothesis that the male calling song of the species shows strong differentiation between the northern (Pannonian) and southern (Balkan) parts of its distribution range, reflecting its disjunct distribution. Our analyses confirm this hypothesis, separating analyzed specimens of I.modestior into two main groups - one present in the central part of the Balkan Peninsula (representing Isophyamodestior sensu stricto), with the second group occurring in the Pannonian Basin, Dinarides, Slovenia and NE Italy. The most reliable difference between the groups is the duration of the main syllable, the number of stridulatory teeth and nu
