Terebellides mira sp.n. Figs 9, 10, 11 Holotype: ANDEEP II, St. 133 - 5, GKG [drawing, MG photo] (ZMH- 26009) Paratype: ANDEEP II, St. 133 - 5, GKG [MG photo, SEM, stub MI 539 & MI 540] (AM W 38719) Description: (Based on both holotype and paratype) Holotype 15 mm in length, 1 mm in width, complete with 28 abdominal chaetigers (Fig. 9). Head region: Tentacular membrane largely expanded, horseshoe shaped. Lower lip rectangular, expanded, but not distinctly folded upwards. Tentacles only short and simple on the outer margins of the tentacular membrane, minute papillae apparent on tentacular membrane with MG staining. Branchiae: Branchial lobes free from each other, lamellae broad, loose, only few present, with filamentous tips. Posterior branchial lobes missing. Fifth branchial lobe absent. Annulation of branchial stem present, stem very long, longer than actual branchial lobe (Figs 9, 10 A, B, D, 11). Anterior chaetigers: Notopodia from segments 3–20, 18 pairs, all notopodia of similar size (Fig. 10 A). Notochaetae, capillaries, graded lengths within fascicle with slightly inflated thecae (Fig. 10 E, F). First neuropodia on thoracic segment 8 (chaetiger 6) with geniculate hooks, about 7 per side, strongly protruding, declining in size within a torus from dorsal to ventral (Fig. 10 G), curved with inflated bases and short pointed tips, base of curve with minute teeth. Subsequent neurochaetae long handled hooks with multiple teeth above a main fang in thoracic segments, and abdominal uncini numerous within a torus and with elongate hooks, main fang completely covered by numerous elongate accessory teeth (Fig. 10 H). Lateral lappets: Present from TC- 1–7, with TC- 1 = 3> 2 = 4> 5 = 6 = 7 or TC- 1 = 2 5
