The effort to uncover herpetofauna within the zone of influence of the Sierra del Divisor National Park has been focused on the northern reaches. The Abujao basin represents the Sierra del Divisor region well in an understudied area central to the Peruvian Amazon. We found 108 species of amphibians and squamate reptiles. Seven records extend ranges from the northern regions, while two records unite with southern regions (Madre De Dios and the Fitzcarrald Arc/Purus valley). There are higher levels of diversity attributable to land-cover units indicative of high terraces and hilly zones, as opposed to low hydromorphic habitats. Our new record for Pristimantis iiap Padial, Gagliardi-Urrutia, Chaparro & Gutiérrez, 2016 brings more resolution to this newly described species. We made observations of an unidentified species of blindsnake, which could represent a unique part of the fauna. Despite variations, we only uphold the presence of various subspecies of Micrurus annellatus Peters, 1871.
