Amiarus (Amiarus) dimidiatus ( Berg, 1879) new combination

Oliarus dimidiatus Berg, 1879 b: 184 (original description).

Remarks. Amiarus dimidiatus is a morphologically distinctive species originally described from four localities in Argentina . Observations on iNaturalist suggest its presence in Brazil and Uruguay, aligning with its description. However, the male terminalia of this species have never been formally described, making specimen-based verification of these records necessary. Examination of male specimens from Argentina , along with unpublished illustrations of a syntype specimen (Mead, unpublished), reveal a close affinity with other species placed in Amiarus (Amiarus) gen. et subgen. nov. (specifically A. deserticola , A. kindli , and A. oryzicola ), supporting their placement together in Amiarus subgen. nov.
