Fig. 6. Chaetal morphology of Pseudopolydora antennata (Claparède, 1868) (formalin-fixed and stained with MG specimens, MIMB 40895). A. Chaetigers 2–6, left lateral view, showing mirror reflected J-shaped arrangement of the anterior-row notochaetae in notopodia of chaetigers 3 and 4, and U-shaped arrangement of spines in notopodium of chaetiger 5. B. Parapodium of chaetiger 5, dorsal superior capillaries missing. C. Notochaetae of chaetiger 5. D–E. Series of bidentate hooded hooks from middle neuropodia, frontal (D) and lateral (E) view. Abbreviations: arrow showing the direction towards the inside of the U-shaped row of chaetiger 5 spines; an = anterior-row spine from notopodium of chaetiger 5; ch2, ch5 = chaetigers 2 and 5; po = posterior-row spine from notopodium of chaetiger 5; su = dorsal superior capillary chaetae; ve = ventral capillary chaetae. Scale bars: A = 100 µm; B = 20 µm; C–E = 10 µm.
