On the Validity of Little-Known Species of Scalpellidae (Crustacea, Cirripedia) Collected by the “Campagnes Scientifiques du S.A.S. Prince de Monaco” from North Atlantic

Resumen

Four little-known species of Scalpellidae collected by the SAS Le Prince de Monaco and described by Aurivillius and Gruvel are reevaluated after examining the type-series: Scalpellum anceps Aurivillius, 1898 is considered a young specimen of Litoscalpellum anceps (Aurivillius, 1898) n. comb. Litoscalpellum meteoria Young, 1998 is probably a junior synonym of this species. Weltnerium pusillum (Aurivillius, 1898) and W. richardi (Gruvel, 1920) are young specimens and hence junior synonyms of Scalpellum scalpellum (Linnaeus, 1767). Scalpellum incisum Aurivillius, 1898 is transferred to Arcoscalpellum and it is considered a senior synonym of Arcoscalpellum atlanticum (Gruvel, 1900). The synonym of Scalpellum alboranense (Gruvel, 1912) with Neoscalpellum debile (Aurivillius, 1989) is reaffirmed.
