DOIAbstract
The genital system is the most thoroughly studied morphological feature in the genus Macrostomum (Platyhelminthes, Macrostomorpha), for two main reasons: 1) taxonomic identification and 2) understanding different mating strategies. In the present study the musculature of the genital system of the freshwater flatworm Macrostomum johni was visualized using phalloidin-linked fluorescent dye by confocal laser scanning microscopy (CLSM), and a 3D model was provided. In the female antrum, two muscular chambers are observed, both attached to the muscular body wall by muscle fibers. In the male system, three muscle sets associated with the stylet are recognized. Finally, we discuss about the interspecific variability of sexual musculature arrangeme...
