Some new species-specific taxonomic characteristics were found at the papillary border and horny beak jaws. The papillae are abundantly distributed and partially arranged in three rows having a wide median gap anteriorly but no medioposterior gap. The horny beak has somewhat roundish serrations and the upper jaw is notched at its frontal margin. These are easily detectable and useful characteristics for species discrimination of tadpoles. In this study, the denticle formula of the tadpoles was 2:4 + 4/1 + 1:2, differing from the generally assumed formula of 2:4 + 4/1 + 1:3. However, the former pattern of the lower lip (/1 + 1:2) is common to Rhacophorid frogs that have been examined throughout the world. This finding is very important in reconsidering the taxonomic position of this species. Unfortunately, we could not confirm the distribution of a stage-dependent number of marginal cusps in this species. However, the number showed 14-17 in stage 38, confirming it to belong to the multiserrate type. © 1996 Oxford University Press Full-length Papers nationallicence SEM nationallicence homy teeth nationallicence denticle formula nationallicence Buergeria buergeri nationallicence tadpole nationallicence Hosoi Mitsuteru First Department of Anatomy, Hiroshima University Dental School Kasumi 1-2-3, Minami-ku, Hiroshima, 734 Japan aut Hasegawa Yoshinori Laboratory for Amphibian Biology, Faculty of Science.
