Planoscalpellum planum (Hoek, 1883) Fig. 23 Scalpellum planum Hoek, 1883: 116, pl. IV, figs 12–13; Murray, 1896: 362; Weltner, 1897: 249; 1900: 307; Gruvel, 1902b: 248; 1905: 87, fig. 97; Schmalz, 1906: 69; Nilsson-Cantell, 1955: 218. Planoscalpellum planum : Zevina, 1978b: 1347; 1981a: 185–186; 1981b: 89; Jones et al. , 1990: 4; Jones, 1991: 153; 2012: 371, 376; Young, 2007: 39–41, figs 47–49, table 10. Material examined. Holotype (dry) NHM UK 2013.1112, Stn 160: Indian Ocean, Eastern; 4758 m. Supplementary description. Young (2007). Distribution. Indian Ocean, Eastern; Pacific, Eastern Central: off Costa Rica, Gulf of Panama. Known depth range 421 to 4758 m. Remarks. The holotype is dry and in poor condition. Designating a neotype is probably advisable in order to stabilise its nomenclature. Genus Teloscalpellum Zevina, 1978 Arcoscalpellum Hoek, 1907: 85 (part); Pilsbry, 1907a: 47; Newman & Ross, 1971: 42 (part). Teloscalpellum Zevina, 1978b: 1350. Diagnosis. Capitulum with 13 or 14 plates; inframedian latus triangular or rod-shaped, umbo apical or sub-apical; carinal latus umbo at basi-carinal angle, not or only slightly extending beyond carinal margin caudal appendage typically multi-segmented (up to nine segments), sometimes one segment or none. Type species. Scalpellum spicatum Zevina, 1975. Composition. 18 species. Distribution. Worldwide, except Arctic; known depth range 90 to 4758 m. Remarks. Zevina (1978b) pointed out that only the basicarinal umbo of the carinal latus distinguishes this genus from Arcoscalpellum , Trianguloscalpellum Zevina, 1978, Anguloscalpellum and Diceroscalpellum Zevina, 1978. Young (1999a) overlooked this genus in his preliminary re-assessment of the Scalpellidae, but did include it in his later assessment (Young, 2007). At present, the phylogenetic position of Teloscalpellum among other genera of the subfamily Arcoscalpellinae has yet to be established.
