Re-description of the external morphology of <em>Phyllomedusa iheringii</em> Boulenger, 1885 larvae (Anura: Hylidae), with comments on the external morphology of tadpoles of the <em>P. burmeisteri</em> group

<p><em>Phyllomedusa iheringii </em>is a leaf frog endemic to the Uruguayan Savanna, which reproduces in water bodies in open areas. Here, based on the lack of some informative characteristics observed on the first description of this species, we re-describe the larval external morphology<em> </em>of <em>P. iheringii</em> from localities in Brazil and Uruguay, and compared them with other species from the <em>P. burmeisteri</em> group. The tadpoles of <em>P. iheringii</em> belong to the suspension-rasper guild. The body length corresponds to approximately one-third of the total length. The body is pyriform in dorsal view and laterally triangular. The snout is rounded in a dorsolateral view. The spiracle is single and almost ventral, not forming a free tube, and sinistral. The opening of vent tube is dextral. The oral disc is anteroventral and anteriorly directed, with single ventral emargination. Marginal papillae uniseriate, interrupted in a wide dorsal gap, and with pointed tips. The labial tooth row formula is 2(2)/3(1). The third lower row is four times shorter than the others. Furthermore, the tadpoles of <em>P. iheringii</em> showed morphological differences in relation to other species of the <em>P. burmeisteri</em> group, this species seems to be smaller in average and have fewer marginal papillae in the oral discs.
