FIGURE 5 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 5. Original illustrations of three described species of Rhabdopleura characterized by direct-frontal inception of ringed erect tubes (A‒C). Erect-tube inception in R. compacta (D‒F) appears to be a form of indirect erect-tube inception. Note that the direction of zooid budding is the same in A to C. A, Rhabdopleura mirabilis (from Sars 1872, pl. 1, fig. 5). B, Rhabdopleura annulata (from Norman 1921, fig. 4). C, Rhabdopleura recondita (after Beli et al. 2018, fig. 2C). D‒F, Rhabdopleura compacta (respectively after Hincks 1880, pl. 72, fig. 8; Stebbing 1970b, fig. 1; Stebbing 1970a, fig. 3).
