Abstract
The nominal African species Pyxicephalus delalandii and Dicroglossus occipitalis have diploid and tetraploid populations. There are also cryptic tetraploid and diploid species similar to Bufo kerinyagae. These represent the 1st bisexual polyploid species so far encountered in the major frog families Ranidae and Bufonidae. The contention that polyploidy is a wisespread and important evolutionary phenomenon in anuran amphibians is supported.
