The turbellarian archetype is widely believed to have been a hermaphrodite lacking asexual reproduction, and such asexual reproduction as is now seen in the Turbellaria (as paratomy and architomy) is generally assumed to have arisen secondarily several times independently. Asexual reproduction clearly prevails among the most primitive metazoans such as the placozoans, sponges, and radiates, however, and if the Platyhelminthes is indeed an early offshoot of bilaterian evolution, as some have claimed, then it is reasonable to expect asexual reproduction to be a primitive feature of the Turbellaria. Asexual reproduction by paratomy or architomy is found in all three main evolutionary lines of the Tlrrbellaria and is most common among primitive groups such as the Catenulida and Macrostomida. The discovery of a new, apparently primitive marine genus of Macrostomida having paratomy widens the known incidence of asexual reproduction within that order. The presence of a muscle ring around the gut of several distantly related genera of the Macrostomida and similarities this ring shows with septa in the division plane of paratomizing species are evidence that paratomy was a feature of the stem species for this order - a feature only secondarily lost in most macrostomids - and suggest that asexual reproduction is a primitive feature for the Platyhelminthes as a whole.},

	abstract = {Macrostomum 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.},
