From April 2001 to March 2002, several species of parasitic larval stages of mites (chiggers) were recovered from 352 lizards (Liolaemus sp.) throughout Argentina. So far, few studies have documented the ectoparasitic chiggers of lizards, and even less is known about their phylogenetic relationships. The phylogenetic relationships among these chigger species were evaluated based on the 18S rDNA, 28S rDNA, and cytB genes. The topology reconstructed provides new insights into the prevalence and distribution of lizard chiggers in Argentina.
