TABLE 1 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

TABLE 1. Summary of key characters of type specimens of the five named New Zealand species of Rhabdopleura. For all columns, metric data pertain to one selected erect tube (or two short tubes if their distal ends are broken) and a representative creeping tube with a clean unbroken sequence of zigzag fusellar sutures between two erect tubes. For each relevant metric, n = number of measurements.
