Twenty-five species of marine Tubificidae are recorded from offshore, largely coarse, shelly sediments as Hutchinson Island on Florida's lower central east coast. Nine species are described as new: Heterodrilus hispidus, H. perkinsi (subfamily Rhyacodrilinae), Phallodrilus hirsutus, Bathydrilus ingens, B. formosus, B. macroprostatus, Coralliodrilus corpulentus, Olavius latus (Phallodrilinae), and Tubificoides annulus (Tubificinae). Redescriptions of Heterodrilus bulbiporus Erseus, 1981, and Phallodrilus acochearis (Erseus and Loden, 1981, n. comb., are provided. Heterodrilus bulbiporus, H. Occidentalis Erseus, 1981, H. pentcheffi Erseus, 1981, and Adelodrilus magnithecatus Erseus, 1979, are recorded from Florida for the first time. The Hutchinson Island tubificid fauna comprises a mixture of warm-temperate (American east coast) and tropical (Caribbean) elements. |
