This study was conducted to determine the species richness and abundance of spiders in Barangay Baganihan, Marilog District, Davao City, Philippines. Sampling was conducted at three sites with elevations of 1000, 1100 and 1200 meters above sea level using conventional collection techniques like sweep netting, beat netting, and vial-tapping. One hundred seventy one spider species belonging to 25 families were recorded. Twenty four species are possibly new species and six species are new record in Mindanao. Highest species richness and the most diverse were recorded in site 2 at an elevation of 1100 meters above sea level. Family Araneidae had the highest species richness and abundance. Species diversity was low in the disturbed sites, sites 1 and 3. The possibly new species and new record for Mindanao in the study indicate that Barangay Baganihan, Marilog District is a species-rich area.
