The geographical variations of the skull in the lesser false vampire (Megaderma spasma) were osteometrically compared between the traditionally-accepted subspecies from Philippines, Borneo, Java, North and South Thailand-Peninsular Malaysia. In female the population from Philippines was larger than any other population in skull size, whereas in male, the size tendency was not clearly found. The population of North Thailand was smaller than the four other populations at least in mean value of measurements in both sexes. The canonical discriminant analysis essentially separated the populations in the scattergrams of discriminant scores. However, the plots of Java, North Thailand and South Thailand-Peninsular Malaysia populations were intermingled in male, and Borneo population could not be obviously separated from the Java and South Thailand-Peninsular Malaysia populations in female.
