Taxonomic Remarks
Polycystididae sp.1 and Polycystididae sp.2 are new species belonging to an undescribed genus within Polycystididae. Both are characterised by a type II prostate vesicle connected to a type II prostate stylet. The ejaculatory duct opens distally into the male atrium (divisa-type). The female system includes a type I female duct, and an insemination duct connects the female bursa to each ovary. The spermatic ducts are filled with sperm, functioning as seminal receptacles. Consequently, Polycystididae sp.1 needs only to be compared with Polycystididae sp.2. The stylet of Polycystididae sp.1 bends at approximately 90° at midlength, forming an L-shape, and measures ~130 µm in length. Otherwise, the stylet of Polycystididae sp.2 is 133 µm long, bends almost distally, and bears subterminal lateral dilatations.
