New and Little‐Known Species of Deep‐sea Tubificidae (Oligochaeta) from the North‐West Atlantic
Eight species of Tubificidae are reported from deep‐sea samples taken south of Massachusetts. Phallodrilus grasslei sp. n., with heavily muscular vasa deferentia, and penial setae, two per bundle, oriented with ectal ends obliquely pointing towards the anterior, and P. rostratus sp. n., with a long...

| Summary: | Eight species of Tubificidae are reported from deep‐sea samples taken south of Massachusetts. Phallodrilus grasslei sp. n., with heavily muscular vasa deferentia, and penial setae, two per bundle, oriented with ectal ends obliquely pointing towards the anterior, and P. rostratus sp. n., with a long and narrow, snout‐like prostomium, heavily muscular, tripartite atria, and small, hooked penial setae, about five per bundle, are described. Phallodrilus biparis Erséus, previously known only from off France in the north‐east Atlantic, is reported and depicted. Taxonomic notes are provided for Adelodrilus voraginus (Cook), A. fimbriatus Erséus, Bathydrilus asymmetricus Cook, and B. atlanticus Erséus. The depth distribution of all eleven deep‐sea tubificid species known to occur south of Massachusetts are briefly discussed. |
