The paper describes three new macrodasyidan gastrotrichs from the Bergen area, western Norway and is part of a series of papers with the scope of describing the Norwegian marine gastrotrich fauna in order to extend the knowledge of Norwegian biodiversity. Paraturbanella scanica sp. n. is described in the family Turbanellidae, and Tetranchyroderma norvegicum sp. n. and Ptychostomella bergensis sp. n. are described in the family Thaumastodermatidae. P. scanica and T. norvegicum were typically found in medium to coarse sand/shelly sand, while P. bergensis inhabits shell gravel. P. scanica belongs to the species group with lateral adhesive tubes. T. norvegicum particularly bears great resemblance to T. coeliopodium BOADEN, 1963. P. bergensis lacks eyespots and has a paired row of ventral adhesive tubes. A tabular key to the genus Paraturbanella is included.
