Types.

Ol., Tigrinus ? 11109, Constantinople., C. Olivier”, handwritten, and “MUSEUM PARIS, Famille Olivier, leg. 1995”, “ MNHN EC 1943” printed. The specimen, agreeing with both description and type locality is here designated as the lectotype with: “ LECTOTYPUS Ƥ, Lixus cardui Olivier, Gültekin & Perrin des. 2010”.

Remarks. This species is an important biological control agent against Onopordum weeds, already introduced into Australian region (Briese, 1996), always correctly recognized by subsequent authors.
