The purpose of this application, under Article 75.5 of the Code, is to replace the holotype of the scorpion Cercophonius brachycentrus bivittatus Thorell, 1877 (currently Orobothriurus bivittatus) from Argentina by the designation of a neotype. The taxonomic identity of O. bivittatus was recently assessed through hemispermatophore morphology, a feature present only in adult males. The holotype of bivittatus is a damaged juvenile, lacking definitive characters essential for specific identification within the genus Orobothriurus. It is proposed that all previous type fixations for Cercophonius brachycentrus bivittatus are set aside and a neotype is designated.  Keywords. taxonomy; Arachnida; Scorpiones; BOTHRIURIDAE
