DESCRIPTION OF TADPOLES OF 3 SPECIES OF SCINAX (ANURA, HYLIDAE)

Larval morphological characteristics have been used to cluster species of Scinax in seven species groups and to support the monophyly of som e of these groups. However, our present knowledge of Scinax tadpoles i s incomplete; currently, tadpoles of only 21 of the approximately 80 r ecognized species have been described. Herein, we describe and illustr ate the external morphology and oral disc characteristics of larval Sc inax berthae, S. nebulosa, and S. boesemani. The presence of a ''labia l arm'' supporting the P3 tooth row in S. boesemani, and its absence f rom S. nebulosa, is discussed in the light of our limited knowledge of tadpoles of species of other Scinax.
