Five species of Gonocephalus lizards (N = 27) from Peninsular Malaysia were examined for gastrointestinal helminths: Gonocephalus abbotti (n = 6),Gonocephalus bellii (n = 8),Gonocephalus chamaeleontinus (n = 4),Gonocephalus grandis (n = 5),Gonocephalus robinsoni (n = 4). The aggregate helminth community consisted of two species of Cestoda, represented by Oochoristica javaensis and cysticercoid and nine species of Nematoda: Abbreviata borneensis, Cosmocercoides malayensis, Falcaustra malaysiaia, Meteterakis singaporensis, Orneoascaris sandoshami, Strongyluris calotis, Physocephalus sp., Physalopteridae gen. sp., Ascarididae gen. sp. Species of Gonocephalus are infected by generalist helminths that have potential for infecting a variety of lizards. Twenty-one new host records are reported.
