Physaloptera lutzi (nematoda, physalopteridae) parásito de liolaemus (iguania, tropiduridae) del noroeste argentino / Physaloptera lutzi (nematoda, physalopteridae) parasite from liolaemus (iguania, tropiduridae) from north-western Argentina

Specimens collected in several localities from and Tucumán provinces (north-western Argentina) Liolaemus quilmes and L. ornatus (oviparous population), and L. alticolor (viviparous population) were dissected. The specimens of lizards examinated have nematodes, in stomach, fore-gut and cloaca, identified as Physaloptera lutzi Guimaraes, Cristófaro and Rodrigues, 1976. This represents the first record for this parasite from Liolaemus species in Argentina. Morphologic and morphometric parasitological studies were done. The specimens were drawned and photographed. Also, the following parasitic infection indexes were calculated: prevalence, mean and maximun intensity
