Additional information Traditionally, Thoracica were often divided into the Pedunculata and the Sessilia. The diagnosis of Pedunculata (stalked barnacles) were the possession of a body divided into a peduncle (stalk) and a capitulum, but this is clearly a plesiomorphic condition and the taxon is accordingly not monophyletic. Buckeridge and Newman (2006) revised Thoracica and divided Thoracica into orders Cyprilepadiformes (fossil only), Ibliformes, Lepadiformes, Scalpelliformes and Sessilia (non-stalked barnacles), but did not base this division by morphological apomorphies or molecular phylogenetic data (because this was not then available). Based on this we follow Gale (2014b, 2018) in dividing the Thoracica into Phosphatothoracica and Thoracicalcarea. The Phosphatothoracica is clearly paraphyletic when extinct taxa are included, but it is a very convenient concept to host phosphatic thoracicans, many of which cannot easily be put into a resolved phylogeny. The Thoracicalcarea comprise all extant Thoracica except the Ibliformes and is monophyletic in all molecularly based analyses.  [details]
