Remarks. Monné (2024a) and Tavakilian & Chevillotte (2023) reported Cerambyx bilineatus as having been described in 1795. However, according to Bousquet (2016): “This volume [4] is usually dated 1795, the date on the title page. However, due to a diplomatic and scientific mission of Olivier to the Ottoman Empire, livraison 23, which comprised about 3/4 of the volume (? starting at page 81 of Capricorne), was published in 1800. It was recorded on the Fructidor an VIII (= 18 August–22 September 1800) issue of the Journal général de la Littérature de France.”

Cerambyx bilineatus was probably described based on a single specimen. According to Monné (2024a) and Tavakilian & Chevillotte (2023), the holotype is a female. Olivier (1800) did not know where it was from.

Dalman (1823) described Trachyderes scabricollis based on a single specimen with type locality ignored. Dupont (1838) described Trachyderes dejeanii based, apparently, on a single specimen from Brazil; Trachyderes solieri based, apparently, on a single specimen from Brazil; Trachyderes duponti based, apparently, on a single specimen from Brazil; Trachyderes olivieri based, apparently, on a single specimen from Brazil (Bahia); Trachyderes puncticollis from Argentina (Cordoba); Trachyderes vauthieri based on a single male from Brazil; Trachyderes dorbignyi based on a single specimen from southern Brazil; Trachyderes nigripennis based on a single specimen from southern Brazil; and Trachyderes signaticollis based on at least two syntypes from southern Brazil.According to Monné (2024a) and Tavakilian and Chevillotte (2023), T. signaticollis was described based on a holotype. However, Dupont (1838) reported: “Nota. Nous avons vu une variété de cette espèce don’t le corselet était presque entièrement noirâtre [Note. We saw a variety of this species whose pronotum was almost entirely blackish].” Bates (1870b) synonymized T. scabricollis, T. dejeanii, T. solieri, and T. duponti with T. bilineatus . Aurivillius (1912) considered T. puncticollis as just an aberration of T. bilineatus; thus, he synonymized this species with T. bilineatus . Monné & Martins (1973) synonymized T. dorbygnyi, T. nigripennis, T. signaticollis, and T. vauthieri with T. bilineatus . Martins (1975) synonymized T. olivieri with T. bilineatus .

Currently, it is known from Venezuela, Brazil (Rondônia, Maranhão, Mato Grosso, Goiás, Rio Grande do Norte, Paraíba, Bahia, Minas Gerais, Espírito Santo, Rio de Janeiro, São Paulo, Paraná, Santa Catarina, and Rio Grande do Sul), Bolivia (Santa Cruz), Paraguay, Argentina (Catamarca, Santiago del Estero, Córdoba, San Luís, and Chaco), and Uruguay (Monné 2024a; Tavakilian & Chevillotte 2023). Zajciw (1966) listed the Brazilian state of Ceará, which was omitted in Monné (2024a).
