The taxonomy of mammomonogamids parasitic in ruminants is discussed with regard to their different rates of variability in Cuba and Mexico. Since their variability is large and the existence of biological species is not based on their morphology but on the reproduction isolation of populations, the authors came to the conclusion that the specific analysis of mammomonogamids will be convincing only in case that it is carried out using taxonomic experiments of special orientation.
本文讨论了寄生于反刍动物的单殖吸虫的分类问题，涉及它们在古巴和墨西哥不同的变异率。由于它们的变异很大，且生物物种的存在并非基于其形态，而是基于种群的生殖隔离，作者得出结论，只有在使用特殊定向的分类实验进行单殖吸虫的具体分析时，才具有说服力。
