Neoscalpellum ovatum (Hoek, 1883) Fig. 8 Scalpellum ovatum Hoek, 1883: 69, pl. VI, figs 7–8. Neoscalpellum marginatum : Newman & Ross, 1971: 96. Neoscalpellum ovatum: Young, 2007: 67. Material examined. Holotype NHM UK 2013.1075, Stn 216: Pacific, Western Central (North of New Guinea); 3065 m. Diagnosis. Hoek (1883) only, no appendage descriptions are available. Distribution. Pacific, Western Central. Known depth 3065 m. Remarks. This specimen was taken together with the holotype of S. marginatum identified by Hoek (1883) and was described by Hoek (1883) “after much hesitation” as a new species, Scalpellum ovatum (the name S. ovaliscus is given on the old label in the NHM collection). Scalpellum ovatum was considered to be a synonym of N. marginatum by Newman & Ross (1971) but was reinstated as a valid species by Young (2007). In neither case was the holotype studied. We follow Young in maintaining the two species as valid until further comparative study of both holotypes can be undertaken. Subfamily ARCOSCALPELLINAE Zevina, 1978 Genus Amigdoscalpellum Zevina, 1978 Arcoscalpellum Hoek, 1907: 85 (part); Newman & Ross, 1971: 42 (part). 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.
