Three new species of Echinoderes (Kinorhyncha: Cyclorhagida: Echinoderidae) are described from two Northeast Atlantic seamounts and the adjacent deep-sea floor. Echinoderes apex sp. nov. from the Great Meteor Seamount and the Sedlo Seamount is characterized by a combination of: a small trunk length (165-215 Vm); middorsal acicular spines on segments 4, 6, and 8; tubes ventrolaterally on segment 2, lateroventrally on segment 5, and laterodorsally on segment 10; lateroventral acicular spines on segments 6-9; long lateral terminal spines, 60.0-80.2% of trunk length; and type-2 glan- dular cell outlets subdorsally on segment 2, sublaterally on segment 6, and lateral accessorily on segment 8. Echinoderes bathyalis sp. nov. from the deep-sea floor near the Sedlo Seamount is characterized by a combination of: a small trunk length (224-243 Vm); middorsal acicular spines on segments 4-8 with a spine on segment 8 being very long (ca. 50% of trunk length); lateral accessory tubes on segment 5; lateroventral acicular spines on segments 6-9; and type-2 glandular cell outlets midlaterally on segment 2.

Echinoderes apex occurs on two seamount summits, whereas E. meteorensis occurs on one seamount summit, and no species occur both on a seamount summit and on the deep-sea floor. |
