Resumo

A new species of deep-water barnacle belonging to the family Scalpellidae is described from the western central Pacific. Based on the presence and absence of radial stripes on the surfaces of the plates, the 23 species of the genus Amigdoscalpellum can be divided into two groups. In the species group with radial stripes, the new species here described, A. dorsituberculatum sp. nov., differs from other species by the dorsal part of the carina being round and arched, the roof without lateral ribs and median furrow; the infra-median latus wider triangular, its length on the basal margin greater than its height; and by the vestigial form of the caudal appendage. A key to the species of Amigdoscalpellum is provided.
