Although monogenean systematics is often based on the morphological analysis of sclerotised structures, their variation with size or age is rarely investigated. Two hundred specimens of the monocotylid Dendromonocotyle pipinna Chisholm and Whittington 2004 were studied. In the haptor, the numbers of marginal papillae, of sclerites in the marginal papillae and of sclerites in the septa did not change according to the size; however, the mean interval between the sclerites in the septa increased linearly with body length. This suggests that, at least in certain cases, valuable systematic descriptions can be made on incompletely grown monogeneans.
尽管单殖吸虫系统学通常基于硬体结构的形态分析，但它们的大小或年龄变化很少被研究。本研究对 200 只单子叶单殖吸虫 Dendromonocotyle pipinna Chisholm 和 Whittington 2004 进行了研究。在固着器中，边缘乳突的数量、边缘乳突中的小骨片数量以及隔片中的小骨片数量均不随大小而变化；然而，隔片中小骨片之间的平均间隔与体长呈线性增加。这表明，至少在某些情况下，可以对不完全生长的单殖吸虫进行有价值的系统描述。
