Gonatodes vittatus as Prey of Hemidactylus palaichthus and Potential Prey of Scolopendra gigantea

Stevland P. Charles, Stephen Smith

Abstract


Gonatodes vittatus  (Lichtenstein 1856) (Reptilia: Sauria: Gekkonidae) or the Streak Lizard (Quesnel 1957) ranges across northern regions of Colombia and Venezuela and into Trinidad and Tobago (Rivero-Blanco 1979; Murphy 1997). It is a very familiar lizard, seen even in urban areas in Trinidad and Tobago. Unlike the majority of its congeners, it is particularly associated with dry forest edge and savannah environments and is very common on Cha- cachacare Island off Trinidad’s northwestern peninsula. Little is known regarding the animals that commonly prey upon the members of the genus Gonatodes. Rivero-Blanco (1979) suggested that birds and snakes are probably the main predators of Gonatodes. Others have discovered Gonatodes in the stomach contents of a number of leaf litter foraging snake species (Dixon and Soini 1975; Martins 1991; Ávila-Pires 1995; de Albuquerque et al. 2007). Quesnel (2008) reported the large gecko, Thecadactylus rapicauda (Houttuyn 1782) preying upon male Gonatodes vittatus in Trinidad. Here we report on two other possible predators of the lizards of the genus Gonatodes.
