Abstract

Contact zones between Israeli Ptyodactylus species were evaluated from museum material and hybridization experiments, the first controlled hybridization between gekkonid species. In southern Israel and Sinai P. guttatus and hasselquistii are partly sympatric, occasionally syntopic. Intermediate specimens were absent and experimental hybridization failed. Probably prezygotic isolation operates. In northern Israel, P. guttatus and P. puiseuxi are parapatric; in and near their boundary, occasional putative hybrids occur. These resemble the few laboratory hybrids obtained. No F2 were obtained. Probably the two species are separated by a combination of partial isolating mechanisms.
