Abstract
Twenty species of reptiles are recorded from the Mortlock Islands,
Chuuk, Federated States of Micronesia. The eight geckos and eight skinks together
comprise 80% of the herpetofauna; amphibians are absent. Most of the
species are widespread in the west-central Pacific, but the recently described
gecko Lepidodactylus oligoporus is known only from the type locality on Namoluk
Atoll. Hemidactylus frenatus appears to be displacing Gehyra mutilata, which is
common only on Namoluk Atoll, where H. frenatus is unrecorded. Five species
of skinks of the genus Emoia are sympatric on Satawan Atoll. Partial habitat segregation
was observed in three morphologically very similar species of Emoia,
with E. cyanura being more frequently encountered in beach strand and other
open, sun-exposed areas; E. caeruleocauda in shady forest; and E. impar in sundappled
forest patches.
