FIGURE 11. Discantenna metallica n. sp. Paratype and other colonies. A, B, D, F, G, paratype 2, ZIRAS 3/50702; C, E, H, I, paratype 1, ZIRAS 2/50676; J, L, N, P, specimen YMG4–06, Stn 69; K, M, O, Q, specimen GLD4–08, Stn 151. A, fertile colony with broken base and small capitulum; B, D, same, showing gonozooid in frontal and apertural views; C, E, a second gonozooid with longer ooeciostome; F, G, high- and lower-magnification views of terminal diaphragm, showing skeletal microstructure; H, I, ooeciopores of gonozooid in C and E; J, N, lateral and apical views of colony with small lobate capitulum; K, O, lateral and apical views of another colony with a small capitulum that is more symmetrical; L, M, parts of stalks with short autozooidal peristomes and terminal diaphragms; P, Q, proximal parts of two colonies in post-ancestrular region. Scale bars: A, J, K, N, O, 250 µm; B–E, L, M, P, Q, 100 µm; F–I, 25 µm.
