Última A cladistic re-assessment of the <i>Polycystis</i> species complex (Polycystididae, Eukalyptorhynchia) OMA Artois, T.J.; Schockaert, E.R.. The taxonomy of the genus <i>Polycystis</i> Koelliker, 1845 <i>sensu</i> Schockaert & Karling, 1975 is discussed. Character analysis reveals the monophyletic state of the three species groups these authors defined within it. As no synapomorphies for the three groups can be found, the genus is split in three genera: <i>Polycystis</i> Koelliker, 1845, <i>Macrorhynchus</i> Graff, 1882 and <i>Paulodora Marcus</i>, 1948. The systematic position of <i>Macrorhynchus yaganus</i> (Marcus, 1954) Evdonin, 1977 is also discussed, resulting in the erection of the new genus <i>Marcusia</i> gen. n.

Ano: 1998 URL: http://www.vliz.be/nl/open-marien-archief?module=ref&refid=6815 The anatomy and ultrastructure of the proboscis in <i>Zonorhynchus</i>-species and implications for phylogenetic relationships within the Eukalyptorhynchia Meixner, 1928 (Platyhelminthes, Rhabdocoela) OMA De Vocht, A.J.-P.; Schockaert, E.R.. The ultrastructural morphology of the proboscis in species of the genus <i>Zonorhynchus</i> Karling, 1952 is investigated. The proboscis epithelia are organized in four belts. The apical cone epithelium has intra-epithelial nuclei, and the distal belt of the sheath epithelium is formed by numerous cells lacking a distinct pattern. Multiciliary receptors are lacking. The diversity in ultrastructural data on the proboscis is used to elucidate the phylogenetic relationships within the Cicerinidae and Eukalyptorhynchia. A bipartite cone epithelium as found in <i>Zonorhynchus</i>-species is a common feature for all eukalyptorhynch species investigated. A syncytial basal cone epithelium is a synapomorphic character for all species except...
