Reproduction in a gecko assemblage
Reproduction is described for four phyllodactylid geckos, Phyllopezus maranjonensis, Phyllodactylus delsolari, P. thompsoni and P. reissii from the upper Marañon Valley, Peru. Observations
were made between March and May 2010 and voucher specimens, already housed in the Zoologisches Forschungsmuseum Alexander Koenig (ZFMK), were X-rayed to check for gravid females. Gravid female P. maranjonensis, P. delsolari and P. reissii contain two eggs, whereas P. thompsoni produces a single egg that is deposited in leaf litter or crevices of stone walls. It is likely that females of all of these species produce multiple clutches in one year; the reproductive period seems to be extended in at least two species. Furthermore, measurements of numerous specimens of all four species are presented herein, revealing that Phyllopezus maranjonensis is the largest species of New World geckos.
