Three new species of the genus Macrostomum, Macrostomum sinensis sp . nov., Macrostomum acus sp. nov. and Macrostomum obtusa sp . nov., inGuangdong Province of China are described in this paper.

(Rhabditophora, Macrostomorpha)0 anew model organism among the lower Bilateria and the use of digi  a114–1260 v433 aMacrostomum lignano n. sp. is a member of the Macrostomorpha, the basal-most subtaxon of the Platyhelminthes, Rhabditophora. This new species can be easily cultured in the laboratory and has been already the subject of several developmental/evolutionary studies. The small size, with only about 25 000 cells constituting the major bilaterian organ systems, makes this simultaneous hermaphrodite a possible candidate for a new model organism that is phylogenetically more basal than any of the model organisms currently used in such studies within the Bilateria. M. lignano belongs to the largest genus of the Macrostomorpha. Over 100 marine, fresh water and brackish water species are contained in the genus Macrostomum, some of them with worldwide distribution pattern. Within it, M. lignano is a member of the M. tuba-species group, which we have summarized here. In the species description, we have used a novel approach to document such small soft-bodied meiobenthic organisms: we provide extensive digital micrographical documentation, which are deposited as a CD together with the type material.10aMacrostomum1 aLadurner, P.1 aSchärer, Lukas1 aSalvenmoser, W.1 aRieger, Reinhard, M  uhttps://macrostomorpha.myspecies.info/node/118202199nas a2200145   4500008004100000245009800041210006900139300000900208490000700217520172700224653001601951100001401967700002001981856005202001       2005                        eng d00aThe marine flora and fauna of the Isles of Scilly: Free-living Plathelminthes ('Turbellaria')0 amarine flora and fauna of the Isles of Scilly Freeliving Plathel  a1-450 v393 aDescribes:

Hitherto only three turbellarian species have been recorded from the Isles of Scilly, Oligocladus sanguinolentus (Quatrefages 1845), Prostheceraeus vittatus (Montagu 1815) and Leptoplana tremellaris (Muller 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.10aMacrostomum1 aFaubel, A1 aWarwick, R., M.  uhttps://macrostomorpha.myspecies.info/node/1129
