FIGURE 7. Rhabdopleura chathamica n in Four new species and a ribosomal phylogeny of Rhabdopleura (Hemichordata: Graptolithina) from New Zealand, with a review and key to all described extant taxa

FIGURE 7. Rhabdopleura chathamica n. sp., A‒C, F, paratype 90265; D, E, holotype 161214: A, part of colony showing three blind side branches, the proximal part of which is adherent; only one ringed erect tube (et) remains. B, close-up of middle side branch in A; note part of the pectocaulus/black stolon (bs) seen through a tear in the cuticle. C, the longest zooid seen, somewhat fouled and partly twisted in profile. D, non-fouled part of another erect tube showing well-developed fusellar collars. E, fusellar sutures on surface of creeping tube, with some point-to-point suture zigzags highlighted. F, close-up of fusellar sutures seen on adherent tube in B. Scale bars: A, 1 mm; B, 300 μm; C, F, 100 μm; D, 50 μm; E, 200 μm.
