Limnodriloides olearius (subfamily Limnodriloidinae), Tubificoides paracrinitus, and T. pequegnatae (Tubificinae) are described from a hydrocarbon seep area of vestimentiferan growth at 540 m depth south of Louisiana. The tubificids are associated with vestimentiferans, mussels and bacterial mats. Limnodriloides olearius belongs to the winckelmanni-group within the genus, but is unique by its possession of transverse patches of epidermal glands ventrally in segments III-X. Tubificoides paracrinitus is closely related to T. crinitus Erseus, 1989, but is larger and possesses postclitellar body wall papillae, a greater number of setae, and different penes and spermathecae; T. pequegnatae resembles T. bakeri Brinkhurst, 1985 in its setal distribution, but differs in the morphology of its penis sheaths.
