| Summary: | Terebellides sp. A Figs 21, 22 Material examined: ANDEEP II, St. 133-5, GKG 54 (ZMH-26010) Description: Single specimen 7 mm in length, 1.6 mm in width, posteriorly incomplete with 18 thoracic chaetigers. Head region: Tentacular membrane largely expanded and folded. Lower lip rectangular, distinctly expanded. Tentacles only numerous short simple ones on the outer margins of tentacular membrane present (Fig. 21). Branchiae: Branchial lobes free from each other, lamellae broad, loose, with filamentous tips. Posterior branchial lobes smaller than anterior ones (Fig. 22 A). Fifth branchial lobe absent. Annulation of branchial stem not determinable, possibly present. Anterior chaetigers: First chaetiger’s notopodia somewhat reduced in size with chaetae more or less originating from body wall (Figs 21, 22 A, B). Geniculate hooks present on TC-6 (segment 8) only. About 5 per side, strongly protruding, sharply bent (Fig. 22 C). Lateral lappets: Present from TC-1–7, with TC-1=3>2>4=5=6>7 (Fig. 21).
