Abstract
Platydemus manokwari DE BEAUCHAMP, 1962 (Turbellaria, Tricladida, Terricola) is redescribed in detail based upon materials from Guam and Bugsuk Island, the Philippines. The animals measure up 50 to 80mm or more in length and 4 to 8mm in width and black in color with a narrow middorsal longitudinal stripe on the dorsal surface. This species is known as a predator of giant African snails. Geographical distribution and ecology of this land planarian species are also discussed.
