Ants is a one of the biotic components in the forests of Kalimantan, this animal  has a number of diverse species. This study aims to record and analyze the diversity of ant species in the area of Gunung Selindung of Twi Mentibar Village in Selakau Sub-District of Sambas Regency. The research method was purposive sampling where the placement of traps was done intentionally according to the presence of ants in three forest cover areas that is in open, medium and closed fores areas, divided into two area namely terestrial strata and arboreal.
