FIGURE 15 in Six new species of Macellicephala (Annelida: Polynoidae) from the Southern Ocean and south Atlantic with re-description of type species

FIGURE 15. Comparative images of M. gloveri sp. nov., holotype, NHMUK.2018.211 (A, B and C) and M. linseae sp. nov., holotype, NHMUK.2018.9354 (D, E and F): A, D) comparison of length of notochaetae (marked by arrows): Notochaetae are much longer in M. gloveri sp. nov. (A) than in M. linseae sp. nov. (D); B, E) comparison of form of notochaetae: In M. gloveri sp. nov. notochaetal shaft smooth (B), in M. linseae sp. nov. shaft distinctly horizontally striated (E); C, F) comparison of form of neurochaetae: Both species have very similar numerous, wide and flattened neurochaetae. There are also few slender additional neurochaetae (marked by white arrows) and these appear to be different: In M. gloveri sp. nov. (C) the serration is dense, in M. linseae sp. nov. (F) serration is more widely spaced. Scale bar A, C: 300 µm.
