Figure 14 in Phylogeny of the deep-sea cirripede family Scalpellidae (Crustacea, Thoracica) based on shell capitular plate morphology

Figure 14. Cladogram of 23 extant species of Scalpellidae, a consensus tree based on heuristic, unconstrained analysis (PAUP) of 61 shell-plate characters. Nodes numbered, bootstrap support values shown. Numbers of character changes at nodes 3, 6, 9, and 11 are shown; note the major change crownwards of Arcoscalpellum sociabile, at which 27 changes (node 6) occur. Taxa close to Diotascalpellum rubrum [Diotascalpellum angustatum (Geinitz, 1843)] appeared at about 105 Mya, and Catherinum at 75 Mya. This suggests that much of the evolutionary diversification of the family had occurred before the end of the Cretaceous. Molecular groups A and B of Lin et al. (2015: fig. 3) correspond exactly with the Scalpellinae and Amigdoscalpellinae. Abbreviations, Amigdo, Amigdoscalpellum; Arco, Arcoscalpellum; Gavi, Gaviscalpellum; Regio, Regioscalpellum; Dio, Diotascalpellum.
