Abstract:Tokay geckos (Gekko gecko) can be divided into the black tokay and the red tokay. The black tokay distributes in Guangxi and Guangdong of China, and northeastern Vietnam, while the red tokay distributes in Southeast Asia such as southern Vietnam, Laos, Thailand and so on. The estrous calls between the two populations were qualitative and quantitative researched. The results showed by compare analysis that there were obvious differences on the acoustic characteristics of estrous calls between black tokay and red tokay. Court call sequences recorded from red tokays consisted of three phases and those from black tokays contained only first two phases. The first phase of the calls has 0~5 pulse clusters; each of them in turn includes 7~10 pulses. The second phase contains a serial of bi-notes (4~10). The third phase consists of 1~3 mono-notes; each of those is similar acoustically with the second note of the bi-note. The main disparity in acoustical properties between two tokays is that an obvious silent gap between two note of the bi-notes in the black tokay whereas no such silent gap existed in the red tokay. Black tokays differ morphologically in skin patches and granule patterns as well as genetically in karyotypes from red ones. Analyses of mtDNA sequences showed two monophyletic lineages existed in black tokays and red tokays, respectively. Combined with all aspects, we proposed that the species complex of Gekko gecko might contain two sibling species and one subspecies.
