Basitoxus rugosus Gahan, 1894: 224 .

Physopleurus swifti Chalumeau, 2010: 113 .

Remarks. Gahan (1894) described Basitoxus rugosus based on syntypes, at least one male and one female, from French Guiana, and Chalumeau (2010) described P. swifti based on a single male from Brazil (Amazonas). Currently, Physopleurus rugosus is known from French Guiana and Brazil ( Amapá, Amazonas, and Pará) ( Monné 2024b; Tavakilian & Chevillotte 2025). This species is rare in collections ( Santos-Silva & Martins 2003).Therefore, although the species has already been recorded from the Peruvian region of Loreto, we decided to include a photograph of this second female to assist other researchers in future identifications. We believe that the photograph of this female will allow researchers to observe intraspecific variations, which are very common in American Macrotomini (see photograph in Santos-Silva & Ramírez-Hernandez 2025): distance between the upper eye lobes, shape and length of the scape, shape of the anterolateral angles of the pronotum, and shape of the posterolateral region of the pronotum.

Material examined. PERU, Loreto: Iquitos vic., 1 female, 5.III.2021, local collector ( DHCO) .
