Volxemia dianella Lameere, 1884: 86 . Volxemia dianella – Zajciw 1958: 686; 1974: 47. — Damoiseau & Cools 1987: 10. — Martins 1999: 154, fig. 96. — Monné 2005: 172. — Galileo et al. 2008: 17, 118. — Monné et al. 2010: 239.

In the original description of Volxemia dianella Lameere, 1884, the author mentioned that the species was described with 3 specimens: “ 1 ♀ rapportée de Botafogo par Van Volxem; 1 ♂ et 1 ♀ du Brésil, sans localité précise.” (Lameere 1884). Damoiseau & Cools (1987) in their work about the type material of Cerambycidae deposited in the IRSNB mentioned only two specimens of V. dianella: “ 2 syntypes, (6), Brésil: Botafogo, ex coll. Van Volxem & Lacordaire ”. The number 6 refers to the faunistic region (Neotropical + Mexico).

Last year I had the opportunity to visit the Entomological Collection at the Institut Royal des Sciences Naturelles de Belgique, and corroborated the existence of only two type-specimens of Volxemia dianella Lameere, 1884, with no holotype originally designated. In order to promote nomenclatural stability and facilite further identifications of this species, a lectotype and paralectotype are herein designated.
