Turbellaria Polycystididae (Kalyptorhynchia) of the Marseille area: III. <i>Albertorhynchus amai</i> n.g. n.sp.

Abstract

A new polycystidid Albertorhynchus amai gen. et sp.nov. from the Mediterranean Sea is described. The new taxon is characterised by paired gonads, paired seminal vesicles, a bifurcated prostate stylet and an accessory hook, the seminal duct freely opening in the male canal. Two bursal complexes form the female atrial organs: a terminal bursa with internal cuticular lamellae and a bursa of the resorbiens type derived from the common female duct that opens in the dorsal wall of the common genital atrium. Relationships with known Polycystididae are discussed
