Good faunistic data is crucial in order to use Odonata for habitat monitoring and conservation purposes. This research aims to determine the species diversity of the Odonata in selected freshwater systems in Lanao del Sur. Sampling using sweep nets and hand catching was done in nine sampling sites. Sampling was conducted on August 26- 31, October 4-6, October 16-17 and December 16, 2012 for a total of 12 sampling days. Forty six species representing the first record for Lanao del Sur Province comprising 27 dragonflies and 19 damselflies were documented. Higher species richness (S=27) was found in the upstream of Malaig River. Moderate species richness was found in eight sampling sites while low species richness was recorded in the lakeshore of Lake Dapao in Barangay Tuka.
