AbstractThe systematics and phylogenetic relationships of the family Leptodactylidaeare controversial as is the intrafamilial phylogeny of the leptodactylids.Here we analyze the relationships of the leptodactylid subfamily Hylodinae.This subfamily has been considered to be monophyletic and composed of threegenera, Hylodes, Crossodactylus and Megaelosia. In the present study 49characters were used, based on different studies on Leptodactylidaephylogeny. Maximum parsimony methods with unweighted and successivelyweighted characters were used to estimate the phylogeny of the Hylodinae.Upon analysis, the data provided further evidence of the monophyletic statusof the three genera, with Megaelosia being the basal genus and the other twogenera being sister taxa. The analysis with successive weighting results ina more resolved topology of the species subgroups of the genus Hylodes andseparates this genus from Crossodactylus and confirms that the hylodines aremonophyletic.
