| Abstract: | A new oligochaete family, Randiellidae, is established for R. multitheca sp.n. (from the continental shelf off the east coast of the U.S.A.), R. litoralis sp.n. (from Oregon, U.S.A.), R. caribaea sp.n. and R. minuta sp.n. (both from Guadeloupe and Martinique), all members of a new marine genus Randiella. The species are characterized by small single-pointed and somewhat sigmoid somatic setae, slender (generally hair-like) modified genital setae in segment X, sperm funnels in X (if one pair), or in X and XI (if two pairs), very simple male ducts lacking atria, clitellum over XII-XIII, and multiple spermathecae in VII and/or VIII. |
