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).
