Abstract
ABSTRACT Vocalizations of Ptyodactylus hasselquistii cf. hasselquistii from Sinai were analysed spectrographically and compared to those of its geographical neighbour, P. h. guttatus, and of other lizards. The multiple click calls (MC) of these and some other gekkonid lizards have certain basic features in common but vary specifically in details; those of P. h. cf. hasselquistii are outstandingly complex and melodious and show individual variation. The taxon may thus merit species status. The clicky “distress” calls (sensu lato) in this taxon differ from MC call clicks. The squeaky “distress” calls, unlike the preceding call types and like those of other lizards, mainly contain energy above the good hearing range of the geckos themselves.
