Abstract

Hyla bischoffi and H. guentheri share some morphological and call characters with the H. pulchella and H. polytaenia groups. The inclusion of these two species in one of these two groups is still controversial. This study showed that both species have 2n = 24 chromosomes, consisting of five metacentric, five submetacentric, and two subtelocentric chromosome pairs. The nucleolus organizer region (NOR) was located on the long arm of chromosome 10, which also presented a block of heterochromatin in both species. The pericentromeric region of all the chromosomes was positively C-banded. There were no conspicuous differences in the karyotypes of these two species, except for an additional heterochromatic C-band on the short arms of chromosome 6 in H. bischoffi. The karyotypes of these two species were very similar to those of the H. pulchella group and indicate that neither species can be excluded from that group.
