TABLE 3. List of characters with loadings on canonical axes and variation in canonical structure. CAN I, with more than 50% of the variation shown in the analysis is influenced most by the seminal receptacle length and external seminal vesicle length and width; CAN II which contributes about 25% to the total variation in the analysis shows number of proglottids and length of strobila to be most important in separating species.
