The song of the males of this species presented large variations, par- ticulary when compared with those recorded for males caught near ma- drid (Ragge & Reynolds 1998) and g. 11. However, in both cases, the male calling song consists of a series of echemes, lasting for about 1.0- 1.7 s each, at 30°C, made up of about 29-31 syllables repeated for un- de ned periods, at a rate of 15-17/s. In contrast to the males from Ma- drid, each echeme begins at a low pitch reaching maximum intensity af- ter about 1/3 of its duration. The oscillographic analysis showed that the sound consists of both upstroke and downstroke syllables, the later being longer and louder and lasting for 35 ms. The upstroke lasted for 20 ms and could always be recognized. p[1]
