This genus was given sub-family status as the only member of Hyloxalinae in Grant et al. 2006 on the basis of its DNA sequences. It has been recommended this genus be revised to resurrect Cryptophyllobates in order to distinguish between some of the old Colostethus and the aposematic azureiventris. In its current state, this genus is distributed widely throughout the Andes and Amazon basin.
