Nossibeus Evers, 1994: 173 [ Type species: Laius politus Fairmaire, 1880 ]. syn. nov. Remarks The genus Nossibeus was erected for Laius politus Fairmaire, 1880 ( Evers 1994 ) . After observation of this species, including its endophallic structure, it was clear that this species cannot be recognised as another species of the genus Laius . In the present paper, Nossibeus Evers, 1994 is treated as a junior synonym of Laius Guérin-Méneville, 1830 (syn. nov.).
