D20B503F70445D3586AE3FE2A9BE060C.taxon	description	Description. Specimens relatively well preserved, with 21 segments, 12.0 – 51.0 mm in length and 5.0 – 16.6 mm in width. Body shape fusiform, tapered anteriorly and posteriorly (Fig. 2 A, B, Table 2). Pairs of elytra on elytrophores on segments 2, 4, 5, 7, 9, 11, 13, 15, 17, and 19; elytra oval to subreniform, white, slightly transparent, with a smooth surface (Fig. 2 C – E). Dorsal cirri on segments 3, 6, 8, 10, 12, 14, 16, 18, 20, and 21, extending beyond the tips of neurochaetae. Branchiae arborescent; grouped in two, one at base of the notopodia and another at base of dorsal tubercles or elytrophores; starting from segment 3 and ending between segments 18 or 21 (Table 2). Prostomium bilobed, triangular anterior lobes with slender frontal filaments (Fig. 2 F). Median antennae on anterior notch, with a cylindrical ceratophore and subulate style; palps thick, smooth, and end in subulate tips; lateral antennae and eyes absent (Fig. 2 F). Tentacular segment fused to prostomium, with pair of tentacular cirri on each side, and a small acicular lobe at the base of tentaculophore; tentacular cirri slender (Fig. 2 F). First segment not distinct, fused to prostomium. Pharynx with five dorsal and four ventral papillae in one immature individual, but not seen in others (Fig. 2 G). Second segment with first pair of elytrophores, ventral cirri, and biramous parapodia. Third segment with ventral cirri and first pair of branchiae. Fourth to last segments with ventral cirri and biramous parapodia. Notopodia smaller than neuropodia; notochaetae stout, few, arranged in radiating bundles; neurochaetae slender, numerous, forming a fan shape (Fig. 2 H – K). Sexual dimorphism evident. In males, posterior segments modified (Fig. 3 A) with 10 th elytra and elytrophores much smaller than 9 th (Figs 2 D, 3 A, Table 2); ventral papillae present on segments 12 – 13, long, tapering, with slender tips extending to next segment; ventral lamellae on segments 14 – 17, round (Fig. 3 B). In females, posterior segments not modified (Fig. 3 C), with 10 th elytra and elytrophores similar to 9 th (Figs 2 E, 3 C, Table 2); ventral papillae present on segments 11 – 15, short and blunt (Fig. 3 D).	en	Lee, Won-Kyung, Kim, Se-Joo (2024): Distribution extension of a vent scale worm Branchinotogluma bipapillata (Polychaeta, Polynoidae) in the Indian Ocean.
