Glossiphoniidae
Opis:
Taxonomic and biological-ecological information as well as literature pertaining to the eleven Polish representatives of glossiphoniid leeches are summarized. Taxonomic status of many species is unclear, and data on their life histories are often fragmentary. The existence of several different conflicting systems of glossiphoniid classification indicates that the taxonomical value of characters is unclear. The family requires a thorough modern revision. A new generic-level classification of the family is needed. Data on behaviour and life cycless of most species should be supplemented; anatomical variation and differences between the purported forms of glossiphoniid species should be re-examined. A detailed study on the life cycles and variation of the Polish members of the Glossiphoniidae would provide new and valuable data and would allow at least for proposing a good, modern standard of species description without which a world-wide revision is hardly possible.

Piscicola fasciata
Opis:
The studies on the reproductive system of P. fasciata were based on 43 specimens. Two main types of the reproductive system can be distinguished in the studied population. Two types of reproductive system were the most frequent (20.93% each): with symmetrical ejaculatory ducts without a loop and symmetrical seminal vesicles reaching the end of the first pair of testes, situated next to the testes (adult individuals) (fig. 23) and with symmetrical ejaculatory ducts without a loop (fig. 21) and symmetrical poorly developed seminal vesicles situated asymmetrically anterior to the first pair of testes (juvenile individuals). The structure of the reproductive system corresponding with the description of the type specimen (BRUMPT, 1900) was not observed in the studied population.

Opis:
The studies on the reproductive system of P. respirans, based on 115 specimens, have revealed its considerable variability. Two main types of the system can be distinguished: 1) ovaries reaching the first pair of testes, ejaculatory ducts symmetrical, no seminal vesicles (juvenile individuals), 2) ovaries reaching the first pair of testes, ejaculatory ducts symmetrical, seminal vesicles reaching the ends of ovaries (adults individuals). The structure of the reproductive system is correlated with the individual size and age. Because the reproductive system of P. respirans as described by BRUMPT (1900) and SKET ( 1968) based on type specimens designated by them, is found only in a small fraction (c. 4-8%) of specimens, a redescription of the species is necessary, best based on a neotype series.
