According to Jacquelin du Val (1857): “ Acanthoderus circumflexus, Klug ”; and “ Acanthoderus rusticus, Dej., Cat. Col., 3 e édit., p. 362.” There are some mistakes in those statements: 1. The genus was reported as “ Acanthoderus ” instead to Acanthoderes; 2. Klug (1829) described the species as “ Acanthocinus rusticus: 198. Acanthocinus rusticus Dej. (i. litt.) fuscus, nigro-punctatus, coleoptris fascia transversa dentata interrupta grisea.(Minor A. depresso).”

According to Dejean (1835, 1836), “ Acanthoderus . Serville ” is equal to Acanthocinus . “Mergele. Dej. Catal.”; and “Rusticus. Dej. Cuba ” is equal to Circumflexus. “ Klug. id.” As there is no species formally described by Johann Christoph Friedrich Klug as “ circumflexus ” in Cerambycidae, it seems evident that Jacquelin du Val (1857) attributed the species to him based on information by Dejean (1835, 1836), indicating (“ Acanthoderus ” rusticus equal to “ Acanthoderus ” circumflexus Klug). Thus, Klug (1829) described the species as Acanthocinus rusticus (with a description provided, making the description taxonomically technically available (ICZN, 1999)). Accordingly, Acanthoderes circumflexus Jacquelin du Val, 1857 is a junior synonymy of Acanthocinus rusticus Klug, 1829 (= Psapharochrus rusticus (Klug, 1829)) . However, both the conditions demanded by ICZN (1999: Article 23.9.1.1 and 23.9.1.2) to preserve a commonly used name are met, Acanthoderus circumflexus Jacquelin Du Val, 1857 is hereby valid and a nomen protectum (ICZN, 1999: Article 23.9.2), and Acanthocinus rusticus Klug, 1829, is hereby a nomen oblitum. A list of works giving evidence of the validity of Acanthoderus circumflexus by use of its name as a valid taxon is given in the ICZN reference above.
