Segment 1 with tentacular cirri reaching about segment 4. Dorsal tentacular cirri of segments 2 and 3 reaching about segment 9. Ventral tentacular cirri as long as those of segment 1, slightly flattened, with about four chaetae arising from anterior margin of the cirrophores. Dorsal cirri of median segments small, triangular, completely attached basally to weakly developed cirrophores. Parapodial lobes slightly bilobed, with about fifteen chaetae. Terminal end of chaetal shaft slightly swollen distally, with small teeth. Blades rather short. Ventral cirri small and with sharp points. Pygidial cirri subulate, 4-5 times as long as broad. Minute median pygidial papilla present (E. ockelmanni-detail). One band of cilia per segment, both dorsal and ventral.
