ABSTRACT: Riparian zones are transitional ecosystems that provide support to various organisms which are necessary to the stability of ecosystems. Those that comprise the rich community of riparian ecosystems include Classes Chilopoda, Diplopoda, and Insecta. The Angat Watershed Reservation is and within it are rich riparian zones that are home to various organisms under the mentioned classes. The study, Inventory of Classes Chilopoda, Diplopoda, and Insecta in Selected Riparian Zones of Angat Dam within Barangay San Lorenzo, Norzagaray, Bulacan aimed to conduct an inventory study and construct a dichotomous key of the said classes in selected riparian zones of Angat Dam within Barangay San Lorenzo, Norzagaray, Bulacan. In sampling, a total of five stations were established. Each station had three 10 m x 10 m sampling plots positioned along a 60 m transect, with the exception of the fourth station, where the researchers were only able to take samples in one plot. The collection was done through active sampling by hand searching, soil sifting, and the use of a sweep net, whereas passive sampling was done through the establishment of pitfall traps, sticky traps, and light traps. Specimens were preserved with 70% ethanol. The morphological characteristics of specimens were examined and recorded to create a dichotomous key. The collected specimens under the selected arthropod classes yielded to the identification and recording of 51 genera. There was one genus under one order for class Chilopoda; one genus under one order for class Diplopoda; and 49 genera under seven orders for class Insecta. Keywords: Class Insecta, Class Chilopoda, Class Diplopoda, Riparian zone, Dichotomous key
