From: Evolutionary history of Chaetognatha inferred from molecular and morphological data: a case study for body plan simplification

Figure 7

Overview of the current phylogenetic relationships of Chaetognatha as reconstructed on the topology resulting from concatenated nuclear ribosomal genes (see Figure5). Asterisks indicate clades that have been modified from the results obtained in the present study. The dotted lines characterize an unresolved branching. We propose to revive the name Decipisagitta instead of Mesosagitta (i.e., Decipisagitta decipiens, D. sibogae and D. neodecipiens), a genus proposed by Bieri [17]. The fourth and last species of Mesosagitta, M. minima, being now included in Parasagitta, the genus Mesosagitta does not exist anymore. On the right, the surrounded characters states indicate putative loss events. Illustrations after: Alvario [37],[38]; Casanova [70]-[72]; Winkelmann et al. [74].
