PHYLOGENETIC SYSTEMATICS OF IGUANINE LIZARDS (REPTILIA, IGUANINAE) - PARASITOLOGICAL ARGUMENTS

The phenomenon of coevolution in seven genera of lizards from the subf amily Iguaninae, and 22 species of their nematode parasites, was exami ned using cluster analysis of the lizard helminthofauna similarity. Th e resulting dendrogram topology correlated approximately with the evol utionary and taxonomic division of the tribe Iguanini into two monophy letic groups: Amblyrhynchina Queiroz, 1987, and Iguanina Bell, 1825. M oreover, the results suggest that within the Iguanina group, the relat ion between the genera Iguana and Ctenosaura can be considered closer and narrower than it was presumed.
