The marine flora and fauna of the Isles of Scilly: Free-living Plathelminthes ('Turbellaria')
J Nat Hist 39:1-45

Abstract / Notes

Hitherto only three turbellarian species have been recorded from the Isles of Scilly, Oligocladus
sanguinolentus (Quatrefages 1845), Prostheceraeus vittatus (Montagu 1815) and Leptoplana tremellaris (Mu?
ller 1773). A taxonomic collection survey in May 2002 revealed 67 species of Turbellaria. Among these, 46
species are known to science and could be determined because of their sexual maturity. Six species are new to
science. The new genus Scillyvortex gen. nov. is established within the Provorticidae (Dalyelliida). Two
species could only be taxonomically determined to genus level, Prognathorhynchus sp. and Polycystis sp.
(Polycystis naegelii group, Kalyptorhynchia). Fifteen species (Proseriata six species, Kalyptorhynchia four
species, Dalyelliida two species and Acoela, Macrostomida and Typhloplanida one species) were juveniles and
could not be determined to species level. Pelophila lutheri is transferred to the family Convolutidae
(Acoela) based on the presence of a cirrus of duplex type. Pelophila pachymorpha is given the status of type
species of the new genus Pelochildia gen. nov. Remarks are given for all the known species that display
varying degrees of difference from their original description.
