Semirossia is a genus of bobtail squid comprising three species.
Description Semirossia appears very similar to other members of the Rossiinae subfamily, such as Rossia and Neorossia, from which it can be distinguished primarily by the presence of a functional black pouch connected to the photophores and by the fact that, in the male, only the left dorsal arm has been transformed into a hectocotylus.
Both S. equalis and S. tenera reach a mantle length of 50 mm.
Species Semirossia equalis Voss, 1950, greater bobtail squid Semirossia patagonica Smith, 1881 Semirossia tenera (Verrill, 1880), lesser bobtail squid
