Results show that molecularsystematics study can supplement the shortcoming of morphological study onspecies delimitation of Bothriocephalid tapeworms since molecular evolutioncan reflect the intrinsic phylogenetic relationships among species,and sincethe phenetic evolution and molecular evolution are independent processes,with the former reveals more conservative change than the latter.

结果表明形态学研究对于头槽绦虫种的界定存在明显不足，而分子系统学研究可以弥补这个不足；两者在进化上位于不同层次，前者进化速率非常缓慢，相对而言后者更能反映物种间遗传本质上的亲缘关系。
