Islamia trichoniana Radoman, Pseudoislamia balcanica Radoman and Trichonia trichonica Radoman are local endemics and threatened hydrobiids living in Lake Trichonis, Western Greece. The rough initial description of their reproductive organs (i.e. penis, bursa copulatrix and receptacula seminis) is supplemented with new data. The radulae of I. trichoniana and P. balcanica are described in detail for the first time. New records of the three species are given and preliminary data about their feeding regime are provided.
