GASTROINTESTINAL HELMINTHS OF SEVEN SPECIES OF SCELOPORINE LIZARDS FROM MEXICO

Abstract

We examined 404 specimens representing 7 species of sceloporine lizards from Mexico (Sceloporus formosus, S. grammicus, S. megalepidurus, S. mucronatus, S. parvus, S. torquatus, and S. variabilis) for helminths. Two species of Cestoda (Oochoristica scelopori and Mesocestoides larvae) and 9 species of Nematoda (Atractis penneri, Physaloptera retusa, Spauligodon giganticus, S. oxkutzcabiensis, Strongyluris similis, Thubunaea intestinalis, Ascarops larvae, Physocephalus larvae, and Acuariidea larvae) were found. The mean number of helminth species for each species of lizard was 4.7 ± 1.5 SD (range = 3 to 7). Twenty-six new host records and 23 new locality records are reported.
