Knowledge of Philippine herpetofauna is progressively increasing. However, there are still areas in the country that are poorly understood and remain unexplored, particularly in the southern Philippines. Mt. Agad-Agad in Iligan City (Lanao del Norte Province) is a secondary lowland evergreen tropical rainforest in the southern portion of the northern Mindanao region, popular with the general public and a biologically important mountain ecosystem. Herein, we present the species richness and distribution of herpetofauna using standardized sampling methods. We documented 37 species of amphibians and reptiles, recording 20 Philippine-endemic species, three exotic anurans, two threatened reptiles, and one unidentified species of lizard. Species richness was higher in a mixed agricultural area (18 species, n = 108 individuals) compared to secondary growth forest (17 species, n = 86 individuals). This research provides baseline information on the herpetofauna from Mt. Agad-Agad, and additional herpetological knowledge on the distribution and ecology of amphibians and reptiles from the northern Mindanao region.

This study highlights the ecology, natural history, and a new distribution record by providing a unique habitat occurrence record in karst ecosystem and describes a tail anomaly of the endemic Mamanwa Bent-toed Gecko Cyrtodactylus mamanwa in the province of Dinagat. The detection of a new population on Unib Island in the southwestern Dinagat extends the previously known distribution of this gekkonid by approximately 100 km south from its known distribution.
