Amigdoscalpellum Zevina, 1978b: 1349 ; Foster, 1980: 527 ; Liu & Ren, 1985: 206 ; Liu & Ren, 2007: 251 . Diagnosis. Usually of small size, sexes separate, capitulum of female with 13 or 14 partially reduced plates; carinal latus umbo at middle of carinal angle, not protruding; i nframedian latus triangular or baculiform, narrow, umbo apical, occupying progressively less space between rostral and carinal latera during ontogeny, resulting in apex not reaching upper latus ; caudal appendages absent or present with one to seven segments; intermediate segments of cirri III–IV without setae on posterior interarticular margins. Type species. Scalpellum manum Zevina, 1973 . Composition. 22 species. Distribution. Worldwide, excluding Arctic. Known depth range 110 to 6096 m . Remarks. Young (2007: 59) argued that Zevina’s (1978b ; 1981a ) classification was not always based on robust, objective characters and considered that the genus Amigdoscalpellum is an artificial group in need of further revision.
