FONT2 Department of Biological Sciences, Southeastern Louisiana University, Hammond, Louisiana 70402, U.S.A. (2 e-mail: [email protected]) ABSTRACT: Because assumptions of strict host specificity and geographic isolation apparently have been used as criteria in determining species of Oochoristica, studies were conducted to address the effects that these assumptions could have on resolving the taxonomy of Oochoristica. Experimental infections of native fence lizards, Sceloporus undulatus imdulatus, and Indo-Pacific geckos, Hemidactylus garnotii, demonstrated that the exotic tapeworm Oochoristica javaensis lacked host specificity. In addition, tapeworms with gravid proglottids, a stage of development that has not been previously reported for any species of Oochoristica, were obtained from both hosts. Evidence against the assumption of geographic isolation stems from the fact that lizard species known to harbor Oochoristica spp. have been introduced beyond their native ranges, and in some cases, these introductions predate the species descriptions. Lack of support for either assumption indicates a need for more rigorous analyses and experimentation to determine species of Oochoristica.
