Abstract: We report geographic range extensions for two anuran species, Brachycephalus didactylus (Bachycephalidae) and Zachaenus parvulus (Cycloramphidae), recorded during a short-term herpetofaunal survey carried out at mid-elevation (600-900 m) Atlantic Forest sites at the Serra das Torres mountains (21°00’ S, 41°13’ W), in the state of Espírito Santo, SE

Brazil. These two species are reported for the first time in Espírito Santo, representing the northernmost records for both of them and raising to 135 the number of anuran species currently known to occur in the state.
