Cytogenetics of two central Amazonian species of Colostethus (Anura, Dendrobatidae) with nidicolous tadpoles

A cytogenetic study of two central Amazonian species of Colostethus with nidicolous tadpoles indicated that Colostethus stepheni had 2n=24 chromosomes, whereas Colostethus nidicola had 2n=22 chromosomes. These species also differed in their NOR localization and C-banding pattern. These results sugge...
