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

ABSTRACT: A cladistic analysis of 23 extant species of the deep-sea pedunculate cirripede family Scalpellidae was undertaken, based on 61 shell plate characters, and taking the Jurassic-Cretaceous scalpellomorph genus C retiscalpellum as an out-group. The consensus tree shows progressive morphological change from basal to more derived taxa, but a derived group is marked by major morphological innovation, including 27 character state changes that permit subdivision of the family into two sharply demarcated clades - the more basal group is here placed within a redefined Scalpellinae (A rcoscalpellum, A rcuatoscalpellum gen. nov., D iotascalpellum gen. nov., G raviscalpellum, R egioscal
