Abstract / Notes

The new phylogenetic system of the order Polycladida results from comparing the anatomy of all known
polyclads. The order is subdivided into the suborders Acotylea and Cotylea. The condition of the prostatic
vesicle to the ejaculatory duct and its interior constitution are believed to be of highest phylogenetic
value. On the basis of the orientation of the prostatic vesicle to the male tract being free, interpolated or
absent, the Acotylea are subdivided in the Craspedommatidea, Schematommatidea, and Emprosthommatidea,
respectively. In the new system 26 families are included within Acotylea and 16 families within the Cotylea.
New species are described: DISCOPROSTHIDES patagoniensis gen. et sp. nov., Pseudostylochus mactanensis,
NOTOCIRRUS neupommerensis gen. et sp. nov., DIAANGIA mactanensis gen. et sp. nov., CHILIPLANA taltalensis
gen. et sp. nov., Pseudoceros langemaakensis gen. et comb. nov. (Hoploplana grubei] Planocera pellucida
(Mertens, 1833), LEPTOPLANELLA californica (Woodworth, 1894) gen. et comb. nov. (Parviplana californica) and
Gnesioceros sargassicola (Mertens, 1833) and the boreal species Leptoplana tremellaris (O. F. Mueller, 1774)
living on marine sediments are re-described. P. simrothi Graff, 1892 is synonymous with P. pellucida. Other
new genera (33) and new combinations are proposed.
