Résumé

A synopsis is provided of the Antarctic plagiostomid flatworms of the genera Plagiostomum, Plicastoma, and Haploophorum, including one new species, Plagiostomum giganteum sp. nov. The new species is characterized by a relatively large size, absence of a ciliated furrow, short common oviduct which expands to form a diverticulum, strongly muscular and glandular distal sac, well devdoped proximal penis, pharynx variabilis textus, and a terminal mouth. A phylogenetic analysis is performed on the Plagiostomum-group, comprising the genera Plicastoma, Haploophorum, Acmostomum, Tuilica, and Plagiostomum. The analysis is based on 12 terminal taxa and 6 characters (ciliated furrow, infranucleate epidermis, unpaired ovary, paired ovaries, plicate pharynx, pharynx variabilis). The phylogenetic tree proposed has a length of 10 steps and a consistency index of 0.60. The monotypic genus Tuilica grouped with representatives of Acmostomum and it is therefore suggested that T. evelinae is best considered as a species of Acmostomum. In the phylogeaetic tree the genus Plicastoma is positioned at the outgroup node, Plagiostomum is the sister genus of Haploophorum and Acmostomum together, and these last two are sistergroups. Generalized distribution maps are given for the genera Haploophorum, Acmostomum, Plicastoma, and Plagiostomum.
