FIGURE 9. Rhabdopleura francesca 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 9. Rhabdopleura francesca n. sp.: A, section of creeping tube of holotype with a broken erect tube; note the small erect-tube diameter relative to the width of the creeping tube. Rhabdopleura decipula n. sp.: B, holotype NIWA 162592 (left) and paratype 1 (NIWA 161212) colonies on broken shells; C, reflected-light image of part of a paratype 2 colony (NIWA 161213) seen in transparency on smooth shell, showing a loop of one creeping-tube branch curving back on itself, with a narrow crossconnection (cc) of the pectocaulus; erect tubes and zooids (z) and a dormant body (db) also seen. D, SEM image of same colony at lower magnification, with branch loop in C at top right. E, another part of same colony seen in transparency, showing a zooid inside a creeping tube to the left (distal) of a dark dormant body. Scale bars: A, 500 μm; B, 10 mm; C, 1 mm; D, 2 mm; E, 400 μm.
