摘要从潮间带钉螺Zeacumantus subcarinatus中记述了四种吸虫的尾蚴和孢子囊(或雷虫)：一种分属于Renicola属(Renicolidae)的远端剑尾吸虫；一种分属于Microphallus属或Megalphallus属(Microphallidae)的单口剑尾吸虫；一种属于Galactosomum属(Hetero-Phyidae)的巨尾尾蚴；以及一种Philophephmus属(Philogphmidae)的尾蚴。这些尾蚴的形态特征与以前描述的相同属的尾蚴进行了比较。此外，由于在实验室的人工底物上很容易形成囊囊，因此还描述了该种的囊尾蚴。这些尾蚴是寄生在蜗牛Z.subcarinatus上的至少六个双基因物种的多样性群落的一部分，这些物种加在一起，对这种蜗牛的生态和进化产生了重大影响。
Abstract The cercariae and sporocysts (or rediae) of four trematode species are described from the intertidal snail Zeacumantus subcarinatus: a distome xiphidiocercaria assigned to the genus Renicola (family Renicolidae); a monostome xiphidiocercaria belonging either to the genus Microphallus or Megalophallus (family Microphallidae); a magnacercous cercaria of the genus Galactosomum (family Hetero‐phyidae); and a cercaria of the genus Philophthalmus (family Philophthalmidae). The morphological features of these cercariae are compared to previously described cercariae of the same genera. In addition, since the philophthalmid cercaria encysts readily on artificial substrates in the laboratory, the metacercaria of this species is also described. These cercariae are part of a diverse community of at least six digenean species parasitising the snail Z. subcarinatus that, together, have a major impact on the ecology and evolution of this snail.
