Sixteen species of Chaetonotida were found in the region of Roscoff (English Channel) and Arcachon (Eastern Atlantic), four following being new: Xenotrichula quadritubulata, Chaetonotus inaequidentatus (Ch. Schultzei species group), Halichaetonotus atlanticus and Heterolepidoderma arenosum. Two further species, Chaetonotus? Variosquamatus and Aspidiophorus? Paramediterraneus, are reported for the first time from French coasts. Xenotrichula quadritubulata sp. nov. has showed the presence of two pairs of adhesive tubes; a new species group has been created for this gastrotrich. A large hypostomion in Halichaetonotus aculifer and H. atlanticus sp. nov. as well as early hermaphroditic phase in H. aculifer were observed.
